Thank you, my head and hands have never failed, the main thing is not to hurry too much.
for those who are going to repair the box on their own, here is the address for the repair kit for the box [To view this link you need to register]
dimensh, that maybe in the valve body, when the selector is moved to the drive position, the car turns off the engine, everything is in order with the gearbox mechanics. They put another GB, the car went, but I want to repair my own.
but in principle, in the valve body, flushing, lapping, and checking the operation of the solenoids (if they do not click, carefully flare 3 out of 7, the rest are just on plastic plugs and rinse with a screw). although there are still 2 input and output shaft rotation sensors, these change to the rear VAZ abs sensors, well, this is all provided that the brains are intact, and this can be checked by entering the error reading mode.

Hello. Into the account of the box. I went to the G35x diagnostics (I practically bought it) and found an error in the 2nd gear on the computer, the code was not written down. The owner says that from time to time the error appeared earlier, it was simply erased. I myself notice that shifting from the second is more noticeable than when working with other gears, there is a slight push. I'm thinking of going to the automatic transmission diagnostics.
NFINITI G35 2003-2005 R55 RE5R05 the box is identical to mine from the FX45, 2 - direct engagement clutch solenoid valve did you mean this code? In short, the box is most likely just shitty and you need to be brainwashed.
as you can see there is no error in the second gear, check it yourself, maybe the box is overheating, because if at least one of the sensors or solenoids does not work, the box immediately goes into emergency mode and goes on like this until it is thrown off
And how to check errors on the removed valve body?
A distributor is a part of the mechanical device of a car, which is responsible for the transmission of torque from the automatic transmission to the wheels of the drive axle. In this case, the angular velocity of rotation of the source and the wheels may differ from each other. A breakdown of the distributor promises a malfunction of numerous elements of the car, therefore, at the slightest sign of this malfunction (hum in the Infiniti distributor, vibration, etc.), urgent repair or replacement is required.
Our car service Rekpp offers to buy an Infiniti transfer case (new and used) at the manufacturer's price. The cost of repairing an Infiniti handout depends on the car model - check these and other questions with our managers. New Infiniti handouts from official Japanese dealers are always in stock.
Infiniti FX models: 33100-CG000, 33100-1BU0A, 33100-1CA0A, 33100-1CB0B, 33100-1MD0A, 33100-1MD1A;
Infiniti M, Infiniti EX models: 33100-CG000, 33100-CG00B, 31310-41X03, 31310-41X15, 33100-1MD0B, 33100-1MD1A;
Infiniti QX models: 33102-7S11A, 33100-1LA0A;
Infiniti G models: 33100-1CB0B, 33100-1MD0A, 33100-1MD1A, 33100-CG000, 32100-70E00, 32100-80E00, 32100-80E01, 32100-50J00, 32100-50J05, 32100-50J06.
The Infiniti transfer case is highly reliable, and its repair is a rather rare phenomenon. Over the years of working with this distributor, we have found out that the main reason for the breakdown of this unit is on the conscience of the drivers themselves. Incorrect operation, rare braking, drift, racing on rough terrain - all this significantly reduces the resource of the transfer case. Another enemy of the Infiniti handout is long driving on an all-wheel drive on the asphalt, which can knock down even a new Infiniti handout. It is quite easy to identify the malfunction by the characteristic noises and tapping in the handout box. At the same time, the repair and replacement of the transfer case does not take much time and is mainly associated with the replacement of silent blocks or the transfer case chain. The main problem may be the search for components for the Infiniti transfer case in Moscow.

The transfer case is an essential element of the transmission of any four-wheel drive vehicle. The transfer case on Nissan / Infiniti distributes the torque from the engine between the axles to ensure the best possible cross-country ability of the vehicle. In addition, the FullTime 4WD all-wheel drive system with center and cross-axle differentials prevents the occurrence of the phenomenon of power circulation in the transmission (occurs on all four-wheel drive vehicles where there is no center differential due to the difference in the mileage of the front and rear wheels), and also ensures the stable movement of the vehicle (especially low speed) when the engine is running at maximum torque.
Nissan Patrol, Pathfinder, Armada, Navara, NP300, Safari, Seranza, Terrano, Mistral, X-Terra, Titan, Infiniti QX4, QX56, QX80 cars are equipped with a demultiplier - a transfer case with a low gear designed to increase torque to the wheels when overcoming especially difficult off-road sections. On these models of the Japanese concern, the transfer is highly reliable due to its design and does not bring any particular problems to their owners.
Most often, you have to deal with malfunctions of transfer cases (angular gearbox) on Nissan Murano, Qashqai and X-Trail.
Obviously, this unit of the car has colossal loads, especially for those who like to test their apparatus when overcoming various obstacles, therefore, sooner or later, the gears of the main pair wear out, teeth begin to break off, a strong metal knock appears (similar to a hammer blow), the frequency of which depends on the angular speed of rotation of the wheels. Consequently, it becomes necessary to repair the transfer case. When driving with broken teeth of the gear wheel of the main pair, there is a high probability of jamming of the transfer mechanism and rupture of its body.Another reason for the failure of this transmission element is oil starvation. An extremely small amount of oil is poured into the transfer case, usually 0.3 to 0.5 liters. With the wear of the oil seals, leaks begin to appear, which intensify over time. If you do not pay attention to this in time and do not eliminate the cause of the leaks, the oil level will go out of range and the unit will fail.
When repairing a Nissan / Infiniti transfer case, it is very important to use only original spare parts, not to install gears from different main pairs in the same housing, and it is also necessary to ensure the coaxiality of the transfer case and gearbox shafts.
The specialists of the JNI-Motors technical center have developed a streamlined transfer case repair scheme, and together with many years of experience and the availability of all the necessary components, this makes it possible to reduce the repair time for the RCP to 1 day, after which you will have the resource of a new unit.
The designers of Infiniti - Nissan's elite division - have created this crossover according to the classic scheme: a longitudinally located engine and main drive to the rear axle. Moreover, in the younger version, the FX35, the ATTESA E-TS all-wheel drive system, where the front wheels are connected by an electromagnetic clutch after the driving axle has slipped, may well be absent. But cars with a 4x2 wheel arrangement were not supplied to us through official channels.
There is no dispute about design, as well as about tastes, so we will limit ourselves only to a comment: the car is large on the outside, but small on the inside, plus it does not have a good overview.
Chains are forever
Little is known about the negative motors. Over time, plastic valve covers warp, and then oil accumulates in the candle wells, which leads to unstable operation of the ignition system. But oil in wells is also one of the symptoms of cylinder-piston group wear. By the way, oil waste, which is generally not typical for these engines, can reach up to a liter per thousand during aggressive driving. It is not difficult to guess what the oil starvation leads to. Oil losses also occur through the rubber seal of the oil cooler.
Of the engine attachments, only the air conditioning compressor clutch lit up with problems, which is jammed from dirt and rust. As for the timing drive, it is chain, almost eternal.
Separated tank
No need to pull the levers
Among the troubles that got into the statistics, we also note the front propeller shaft, and only for the FX45, and the electromagnetic clutch for connecting the front axle. There is also wear and tear on the rear CV joints, but here everything is clear as a bright day: a powerful heavy machine at abrupt starts loads this unit very much. The chassis is durable. In the McPherson front suspension, only the stabilizer struts require attention, and even then not often - they hold 60-80 thousand km. In the rear multi-link suspension, all parts are long-lasting.
A knock on the steering rack is not always a reason to change it, you have to come to terms with the fact that this is a design feature. Reiki leaks practically never occur.
The short service life of wheel bearings is associated with the profile and size of the wheels. After all, rollers on 20-inch discs are really extremely low-profile, and for broken roads it is better to change them to 18-inch ones.
Are they beating or not beating?
With the electrical part, things are not bad, especially against the background of some competitors with their diseases from the "woe from wits" series. It is only known that the electrical wiring located in the area of the battery niche oxidizes over time. Also related to this niche are complaints about the smell of rotten eggs in the cabin - after all, air is drawn from there.
The "old age" of the music system is manifested in the fact that it stops reading discs. It happens that the driver's seat gets loose over time. In some cases, there is a backlash in the steering column due to a device that raises the steering wheel up for easy boarding / disembarkation. And finally, so that the aforementioned does not create a wrong opinion about the model, let us clarify that, in general, among the competitors of this premium segment, Infiniti FX is quite good. It just requires timely prevention.
The Infiniti brand, a subsidiary of Nissan, appeared relatively recently. At first - to promote luxury models in the American market. Having tasted the fruits of success, the Japanese-Americans decided to conquer Russia, and later Western Europe. Therefore, in the secondary market, there are mainly Russian, so-called dealer, as well as American cars. The choice is huge - let's talk about how not to be mistaken with it.
The owners of Infinity-FX call their cars "dates". And they are appreciated for their extraordinary design and handling. At the same time, the cars have an impressive ground clearance (200 mm) and, as a rule, all-wheel drive. Rear-wheel drive only some "Americans". By the way, the front universal joint does not have grease fittings on the crosspieces, therefore, when worn out (up to 160 thousand km), it is replaced as an assembly for 29,070 rubles.
The CD changer sometimes refuses to read discs. Dealers do not repair, but for 5-6 thousand rubles. you can find masters over the Internet. For 3-4 thousand rubles.they are ready to teach an American receiver to work on Russian radio frequencies, as well as to convert miles and Fahrenheit into kilometers and degrees Celsius that are more familiar to us.
Despite the more attractive price, cars from overseas are still less preferable: the rear lighting technology does not meet our standards, and you can not easily install European lamps - they are not lamp, but LED. In addition, we will have to change the VSM unit, which is responsible for switching electronics (they are different for lamps and LEDs). And then reprogram the keys - an immobilizer is sewn into the block. For everything they will ask 15 700 rubles. Please note that the unit does not like voltage surges and current surges, therefore it is highly undesirable to start up the motor with a dead battery and “light up” it.
In addition, the "Americans" have a much weaker chrome coating of decorative elements of the body, as well as often twisted mileage. It is very difficult to establish the true one: erased errors with the chronology of their appearance, by which you can catch the seller in a trick, can only be seen with the help of factory equipment (the dealer's scanner, alas, is blind). Dealers rely more on secondary signs: wear of upholstery, wear of oil seals, etc. Do not skimp on such diagnostics, especially since it is not so expensive compared to the price of the car itself - some 6,400 rubles.
Typical malfunction: you press the button, and the trunk lock is silent. This is due to the contacts oxidized to dust in the button. If you press harder, you will have to change not only the switch with the bracket, but also the chrome trim of the fifth door.
Check the operation of the buttons on the door handles and the fifth door, rear wiper, rear view camera and horns. Sometimes the climate fan motor burns out - most often due to increased load when the cabin filter is clogged. According to the regulations, it is changed after 30 thousand km, but on dusty roads it is better to reduce the interval. Weakly adheres to the varnish on the door handles; it happens that the electric drives for locking the locks, the fuel level indicator sensor fail, which happens more often again on cars from the USA. But the main thing is that the Yankees save on oil. It seems that they change on time (according to the regulations after 10 thousand km), but they pour what is cheaper.
The S50 model was equipped with VQ35DE (V6, 3.5 L) and VK45DE (V8, 4.5 L) engines. Both codes were in the world's top ten, however, strict environmental standards forced the introduction of collectors - they became the weak link: products filled with precious metals (RUB 81,520 with replacement) became consumables. The problems are the same as on the Nissan-Murano (ZR, 2011, No. 3
Dealers blame bad fuel, and owners, referring to all kinds of forums on the Internet (these engines are put on many models of Nissan and Infinity), blame the manufacturer. Say, the engine control unit does not respond properly to interruptions in ignition, it is late in adjusting the composition of the mixture, which leads to overheating of the catalysts. The truth, apparently, is somewhere in between.
VQ37 engines on the second generation model appeared relatively recently, so it is premature to guess how the neutralizers will behave. The oil dipstick, like on the VQ35 engine, is more convenient than on the V8.
We strongly recommend that you carry out diagnostics before buying a car in order to determine the degree of destruction of the neutralizers based on the signals from the upper and lower oxygen sensors. If the car is already yours, and the process has started - urgently for repair! Remember: for the engine, the wear products of the neutralizers are like a handful of sand. Unofficial ones usually remove the filling and reflash the engine control unit. It's bad, of course, but what to do if the idiot is still not translated at the gas station!
Pay attention to the condition and level of the oil in the engine (do not consider the advice trivial): Infiniti motors tend to devour oil, and the owners sometimes find out about this only by the signal of the emergency pressure lamp. A serviceable engine should consume 100 g of oil per 1,000 km, while the volume between the max and min marks on the dipstick is only a liter.It turns out that even an ideal engine barely fits into the interval between scheduled maintenance (10 thousand km). What can we say about the elderly unit.
Dealers start sounding the alarm when the oil consumption is more than 2 liters per 10 thousand km, being confident from their experience in the excessive wear of the cylinder-piston group (the compression does not reach 11 kg / cm²). And the reason is no longer so important - whether the neutralizers began to crumble, or they overlooked the oil.
Under the hood of the FX45: The dipstick is easily accessible, but the tube is bent sharply in several places, making it difficult to insert. Maybe that's why many owners don't bother checking the oil level? The main VIN and the backup plate are shown by arrows.
The motors are very sensitive to overheating, especially the VK45DE. Consequence - breaks through the gaskets of the block heads, which you will immediately notice on the blackened walls of the expansion tank. The reason is most often in the radiator combs clogged with dirt and fluff. To check them, it is enough to remove the plastic shield above the radiators, but many people neglect such a simple procedure. Like, what is there to watch if you still can't remove the dirt without dismantling the radiators. If your hands do not reach, entrust the cleaning to specialists - it will be cheaper to replace the gaskets.
If the timing drive clanks right after starting a cold engine, it's time to change the tensioner. On a V6, it's easy: remove the drive belts and the hatch in the front of the engine. On the V8, access is not so good - you have to remove the radiators and fans. At the same time, make sure that the latter are in good working order, because with a run under 150 thousand km, one of them probably does not spin anymore. If the speed is floating or the engine stalls at idle, it's time to flush the throttle assembly. Please note that after this you will need to calibrate the dealer's scanner.
In addition to the collectors, a couple of neutralizers are installed under the bottom - they begin to deteriorate only at very high mileage, without affecting the mechanical wear of the CPG. The front universal joint and automatic transmission are still normal here (mileage 134 thousand km).
The Jatco five-speed automatic, although it is called adaptive, is poorly adapted to a sporty driving style - the clutches burn out. Officials do not change them, offering to fork out for a new box (340 thousand rubles with a replacement!). And not because they do not know how to repair, but because of the lack of original spare parts. The plant supplies only control units, valves and valve body assemblies, although there are fewer problems with them. Do not despair: on the Internet you will find many companies ready for 150-170 thousand rubles. tidy up even the most dead unit.
In order not to waste money, regularly check the oil (ATF Matic D, it is DEXRON III): if it turns yellow from red, then it has largely lost its properties and it is time to change, but it has darkened and smells burnt - the gearbox repair is not far off. By the way, according to American regulations, the oil is not changed at all (in Europe - after 60 thousand km), which is another reason for the more deplorable state of the car from overseas. And their handouts often fail, refusing to connect the front axle at the most crucial moment.
The weak link in the rear multi-link is the stabilizer bushings and wheel bearings. Sometimes it is difficult to adjust the wheel alignment angles: fasteners sour. Lubricate the joints with anticorrosive if necessary!
In the front suspension, shock absorbers deserve attention (sometimes they jam), steering rods and stabilizer bushings (they wear out by 100 thousand and 40 thousand km, respectively). The stabilizer struts often hold over 120,000 km. Assembled front hubs and rear hub bearings (changed separately) are not famous for longevity and may start to buzz or play after hitting a seemingly trifling obstacle.
With the brakes, there are continuous worries: both the front and the rear discs often warp, and the pads sometimes wear out for 5-7 thousand km. Even if you drive very prudently, the front ones do not live more than 30 thousand, and the rear ones - 40 thousand km. At the same time, the resource of the front discs does not exceed 80 thousand km, the rear discs - 100 thousand km, but again, if they are not driven earlier.
