Fuck the master))) Complete fucked up)))) Blue, and also rolled. There is dirt all around, half of it collects on the floor)))) Nothing can be washed under pressure. And there is a fucking secret with breaking the central body. Cleaning the lubrication oil channel just killed me, I almost fell off my chair. The assembly is shown as the easiest part. At the end, they started talking about the Manol recycled oil, which cannot be used categorically in cars, especially in this automatic transmission (this includes Type WS). The owner of this automatic transmission (if I was not mistaken, the author of the video) can sympathize with the current so that, as I understand it, the box does not understand completely, and there are a kilometer of engineering flaws in it, and she will live 10 thousand if she went after these drunks. The only positive thing about this video is the sealant, a really good sealant. After such masters, people get the impression that after repair boxes do not go for a long time, after such repairs they will definitely not go

I would leave such service employees at least without a bonus!
Hands from the train. unambiguously. I would never entrust a car to such masters

Good day!)
I ask for advice or even advice on repairing the U660E box.
Automobile
Toyota Camry 3.5L 2007, driving style - calm (including because of the fact that I immediately heard about the weakness of the box paired with this engine)
Background
Absolutely out of nowhere and without any preconditions, a strong vibration of the body appeared at a speed of 50 km / h, from 60 to 80 - very noticeable, from 80-120 - if I drove this car for the first time, I probably would not pay attention, after 120 it is absolutely invisible. An important point - regardless of the speed - you release the gas pedal - the vibration stops immediately. It is also important that vibration does not depend on the speed of the gearbox, that is, it exists both during dynamic acceleration (2-3 speed, rpm around 3-4) and sluggish (4-5 speed, rpm 1.5-2)
Diagnostics
at the station, where the car is serviced, the need to defect the automatic transmission came to light. How the diagnostics took place: they hung it in front of the car, started driving it, holding the brake to simulate the load. Indeed, at 60 km / h, it became clear that the body was already swinging, the engine was shaking (the pillows were definitely intact). They began to hold the right wheel - it seemed like the vibration had disappeared, a certain metallic sound appeared, I would describe it as a grinding sound. According to the diagnosticians - this rattle from the automatic transmission. We held the left wheel - it seems there is a little vibration, there is no grinding.They sent in general to the boxers.
For boxers, the diagnostic method is exactly the same, with the exception that they did not hang the whole in front, but jack up the right side first, then the left side (that is, one of the front wheels remained on the ground). So, with this and with the other version, the notorious grinding was present, vibration, in my opinion, was also there. The diagnostician immediately said - this is an automatic transmission, leave it, it is necessary to disassemble it.
Problems that were already in the box
absolutely not strained and consisted in a one-time re-gasification to cold from 2 to 3 (re-gasification in the region of 500-1000 rpm, if the gas was released just before switching, then it did not appear later) and also to a cold, somewhere in a second load on D (that is turned the selector to D, hold the brake, after about a second you feel a very small soft jolt, although if you release the brake immediately, the car will go and this jolt will simply be in motion). This was told to the receiver of the car, but this was not the reason for contacting the box-operators. These symptoms have already been observed in 20-30 thousand, do not progress.
The revealed noise is also not the reason for the appeal, because I have never heard it and it manifested itself in abnormal working conditions. By the way, later, the master told me that this “rattle” could issue a diff due to a non-standard task for him (one wheel is stationary, the other is spinning) and, accordingly, is normal. However, he himself did not hear it (some people take and diagnose in one place, other people fix it in another place, such is the office) and says that there should be more “crackling” than “grinding”.
Parsing the box
showed that nothing could vibrate and rattle there (the words of the master, who was dismantling the box: “I don't see what could rattle here”). No shavings were found anywhere, the oil was not to say that it was very dirty (it was partially changed with the filter 2 times in the last 40,000 km), the differential is intact without any scratches and traces of “grinding”. On the other hand, the reason for the rebase, again to the master, was obvious. For me, an amateur, according to the results of examining the disassembled box, one can clearly see burnt discs in the drum.
Verdict and estimate
STO offers to change:
valve body;
repair of a fluid coupling;
back cover;
drum assembly;
set of pistons;
pressure plate 5 pcs;
set of friction and steel discs
and of course gum, oil and filter.
All together 101,000 rubles + work.
Questions
1. From all of the above, I am inclined to think that the vibration was still caused not by the box, but by the drives. Accordingly, the box diagnostics made a mistake and in vain dismantled the box for me. And what do you think?
2. Boxers say that it is now impossible to put the box back together (the parts were worn in their own way), right?
3. Since the box has already been opened, then in an amicable way it is necessary to cure the gas overload, but is it really necessary to have such a volume of work and costs that is offered by the boxers?
4. The proposed option, as I understand it, is thorough and for at least another 100,000 run. I don’t want to use the term “make for sale”, but in reality this car will remain with me for a maximum of 10,000 km and I don’t want to invest a decent amount in it. Based on this, is there any other repair option that is not so expensive? Moreover, my intuition tells me that if the vibration is not due to the box, then this very box would have driven these 10 and 20 thousand kilometers without any problems without any problems.
More specific questions, such as “is it possible to repair the valve body and whether it is necessary to change it at all” or “is it necessary to replace the rear cover” I will formulate and ask a little later.
I would be glad to any comments and opinions, thanks in advance)
In 2006, specialists from the Japanese company Aisin developed a six-speed automatic transmission U660E which was intended for front-wheel drive vehicles with a six-cylinder engine. This transmission modification was installed on Lexus, and top-end modifications of Toyota Avensis, Rav4 and Camry.
This transmission was originally intended exclusively for front-wheel drive vehicles. A few years later, a modification appeared in the proposal Automatic transmission U760E, which was intended for installation on all-wheel drive sedans and crossovers. One of the features of this transmission model is its increased reliability and durability. With proper operation, the gearbox could work without the need for major repairs for 10 years and a mileage of more than 200,000 kilometers. At the same time, it should be noted that the U660E automatic transmission is distinguished by its criticality to oil quality. It is recommended to carry out work on changing the oil and filter elements in the gearbox every 50,000 kilometers. The use of low-quality lubricants can lead to serious damage to the transmission.
This transmission has established itself as one of the best models of automatic six-speed transmissions. In terms of smoothness and dynamic characteristics, this modification of the transmission is significantly ahead of manual transmissions. At the same time, thanks to the optimization of the control modes, the most comfortable and smooth switching is achieved. The car can easily realize its dynamic potential, which in turn improves the acceleration performance of the car's comfort.
If necessary repair work, automatic transmission U660E You can use ready-made repair kits that allow you to carry out a comprehensive repair of steel discs and clutches. In most cases, problems arise with the gearbox even with its serious mileage. In rare cases, the solenoid and valve body fail, which leads to the need to replace these elements.

The torque converter is an integral part of the automatic transmission, therefore, when repairing the gearbox
its repair is also necessary. In a torque converter, as in an automatic transmission, it can
many breakdowns occur, for example:
Installing an unrepaired torque converter on a newly restored automatic transmission, you risk immediately breaking the gearbox again, because it will contain all the wear products of the torque converter, and in the worst case, the metal parts of the bearings or blades.
Do you want to buy a used torque converter? Don't rush to make a mistake! It is impossible to guess the quality of the automatic transmission fluid coupling used, moreover, purchased at the same price as a reliable repair. We offer the exchange of your torque converter for an already repaired one from our warehouse, or we can carry out a high-quality overhaul in our workshop.
The cost of repairing a torque converter usually varies from 2,500 (disassembly, flushing and assembly) to 12,000 rubles (in case of serious breakdowns), this is influenced by the complexity of the work, the number and cost of damaged parts. This is cheaper than re-repairing an automatic transmission. The average cost of repairs, including labor and spare parts, is about 4-6 thousand rubles.
We also carry out a quick repair of your torque converter in 1-2 hours right in front of you. You yourself will see all its breakdowns. At the same time, we do not make an extra charge for the urgency of work.
1) Cutting the torque converter.
The weld seam, which connects the two halves, is carefully cut, leaving as much metal as possible. With proper cutting, the torque converter can be easily disassembled and reassembled 2-3 times on occasion. Unfortunately, many transformer repair shops remove all metal from the body the first time they cut it.
2) After cleaning all parts of oil and wear products, the repair itself begins. If necessary, a new torque converter lock-up clutch is glued on, the body surface is leveled under the new clutch. And here unscrupulous repairmen again have problems out of the blue. They grind the case for a new friction clutch so that they cut off almost all the metal through and through, because of this, through cracks then appear. A normal craftsman is neat and does not remove excess metal. Then other necessary spare parts are replaced - bearings, O-rings, oil seal, etc. If necessary, a new neck is welded into the transformer cover. This procedure requires accuracy and precision, since usually unskilled workers are not able to cut a hole in the lid to fit the new neck, but drill it half a millimeter more, which is fraught with runout and imbalance.
3) Assembly.
It is imperative to weld both converter halves back as factory. In this case, it is necessary to minimize the axial runout between the two halves (balancing) and ensure the tightness of the seam. For a good craftsman, even the appearance of the repaired unit matters, which is why, after being repaired in GIDROTOR, the torque converter looks the same as a new one made at the factory.
In the video, the usual average result of our repair is a runout of 6 hundredths of a millimeter with an allowable runout of 3 tenths.
6-speed automatic transmission U660 appeared on cars in 2007 on such brands as the front-wheel drive Lexus (ES 350), as well as "charged" 6-cylinder Toyota (Camry, RAV4, Avensis). The box is considered one of the most modern developments of the company.
The U660F designation denotes the all-wheel drive powertrain, which is often found on flagship versions of SUVs and powerful sedans.
A feature of this box is its reliability and maintainability, as well as the absence of the need to change the oil before the first major overhaul.
Problem areas of automatic transmission U660:
- Weak circlip that holds the main bearing of the housing
The most common symptom of this problem is transmission vibration. In particular, this problem "suffers" cars that experience frequent stress on a cold automatic transmission. The circlip may not be able to withstand the side load from the transmission of rotation to the differential.
Replacing burned-out clutches in this case will not solve the problem - automatic transmission diagnostics with a similar malfunction should be carried out with the obligatory replacement of the bearing and ring.
- Weak drum clutches (DIR, Direct)
Overhaul of this unit happens at the first hundred thousand run, the reason for which was a factory defect in the piston seal. As a result of a drop in oil pressure, not only the drum burns out, but also the consumables of the clutch packs.
Most problems with the U660 automatic transmission can be solved with an inexpensive repair, which should be warned about by the master of this type of transmission. Our car service offers expert craftsmen for this and other types of automatic transmissions - the main focus of REKPP. Over the years, we have thoroughly studied all the ailments of this automatic transmission and are ready to offer our customers guaranteed and professional repairs as soon as possible. If the automatic transmission is repaired, the evacuation of the faulty car to our technical center is free of charge.
All types of bearings inserted into the automatic transmission housing after 100,000 km break the oval seats and rotate inside the housing. Shafts and planetary gears lose their axis of rotation and generate noise in motion.
Maktrans company repairs automatic transmission housings in two ways.
1. Cladding of aluminum by welding
2. Boring and introduction of a steel sleeve with mechanical fixation.
Repaired holes are guaranteed for 24 months.
The body repair of Toyota U660E, U341E, U340E, U240E, U250E, U140E, U150E automatic transmissions is performed by aluminum surfacing. The hardness of the deposited material exceeds the factory specifications.
Toyota automatic transmission repair is a very time-consuming and complicated process. This is usually done by experienced people in a service station or service center. However, after reading the article, it will become easier for you to repair an automatic transmission with your own hands.
The first place to start is to remove all sensors and attachments. After that, we begin to disassemble the automatic transmission box, that is, we remove two bolts for seventeen, four bolts for fourteen and seven pump bolts for twelve. Next in line is the removal of the pallet. Pay attention directly to the filter, it is usually dirty.
The filter is fixed with 3 screws. Having diagnosed the filter, you can tell a lot about the causes of the malfunction of the automatic transmission. After you have removed the filter, brains or hydraulic logic opens up in front of us, in which the blocking valve, pressure valve, three switching valves are located.
Removing the hydraulic logic. To do this, we disconnect the electric solenoid chips and ten bolts on the head. We detach them and remove the brains. After removing the bolts, slowly separate the plate. Please note that you need to immediately remove the drain valve from the fluid coupling and the accumulator.
Once again, we check so that nothing falls and nothing is lost, that is, we check for looseness of some parts by hand. Then we remove the pump by screwing in two bolts on the sides, the bolts, by the way, come from the starter.
We bring the bolts all the way and tighten them with the head, you do not need to use force, as it can be damaged. After doing these manipulations from the side, we loosen the two bolts by twelve that hold the pan. Then we take it out and immediately look at the presence of malfunctions. Attention! Turn the saucepan over carefully, as small parts may fall out of it.
DIY Toyota automatic transmission repair must be very neat, so we arrange all the parts of the automatic transmission in order so that during assembly we do not get confused about what and where to attach. Then we take out the fourth speed package, which increases the row.
Next, we inspect the bearing washers, but be extremely careful with them, because they may fall, and you, from the abundance of parts in the automatic transmission, will not be able to guess that it was there. We disconnect the stopper, which can cause some difficulties, you can resort to using a screwdriver, but everything should be done very carefully so as not to damage anything. Most often, when diagnosing automatic transmission, bushing wear is detected, due to which the shafts begin to walk.
Here you can also see what turned the bearings, that is, they turn them in the inner race. All defective parts should not only be found but also replaced.
Any repair with your own hands is quite profitable financially, since you do not need to give your hard-earned money to specialists. But, if you are not very confident in your abilities, contact the service station, where they will help you save some time and wasted nerves. However, remember that any work done with your own hands is of higher quality, since you are unlikely to save money on your car.
