Changing the solenoid block for the 41TE transmission (Chrysler)
Chrysler began using a new solenoid block in 41TE transmissions. Outwardly, it differs significantly from previous models (Fig. 1a and 1b) so that it will be difficult to confuse it with models of an earlier release.
Chrysler began producing the new block from mid-1999. The new solenoid block fits all previous models up to 1989. The design changes include improving and simplifying the layout inside the case, which allows for less noisy operation of the solenoids. A special plastic plate is installed, which is a sound-absorbing shield, the role of which was previously played by the cover of the solenoids block. Therefore, the need to use this cover has disappeared, and it is no longer installed.
The outer cover of the new model of the solenoid housing also has a warning (Fig. 2) warning of adjustment errors caused by disassembly of the solenoid housing. However, the new body of the solenoid block is more resistant to changes in adjustments when it is opened.
The biggest change in the solenoid block is the simplification of the design of all solenoids. Previously, the solenoid coil, tappets, balls and valve seats were assembled and adjusted at the final stage of assembly of the solenoid block body. The new design integrates all of these elements, which significantly reduces the chance of solenoid failure caused by improper assembly of the solenoid box housing or incorrect adjustment (Fig. 4).
If it is necessary to dismantle a new solenoid block due to contamination, pay attention to the following points:
1. When separating the part of the block of solenoids in which the solenoids themselves are installed, it is very easy to damage the pins of the connectors for installing the solenoids, which are located in the plastic part of the case (Fig. 5). In previous models, when disassembling the case, the solenoids remained in the plastic part of the case, and each solenoid could be removed from it separately (Fig. 6). In the new design, the solenoids remain in the aluminum part of the housing (Fig. 7), so it is necessary to simultaneously disconnect all the connectors of the solenoids in the plastic part of the housing.
In order to separate the halves of the case, you should shake the plastic case up and down, so that these halves can be separated by hand (Fig. 8). Never use any tools for this. If one of the contact leads showed too much resistance, then use a pointed object to slightly bend it (Fig. 9). Do not bend the contact lead too much! Otherwise there will be poor contact with the solenoid.
2. When installing the solenoids in the aluminum case, make sure that the solenoids are oriented as shown in Figure 10. If the solenoids are reversed 180°, the contacts will not make proper contact with the pins in the plastic case and will break.The pressure sensors located closest to you in the figure should be installed as shown in figure 10.
3. When connecting the two parts of the body of the solenoid block, it is better to use silicone sealant rather than a rubber gasket (fig. 11a and 11b). When using sealant, make sure the bead of sealant fills the entire groove and rises slightly above the parting plane.
When installing a new solenoid box in older vehicles, it is not necessary to use the plastic solenoid box cover, which is designed to reduce noise. The mounting bolts for the new solenoid assembly should be 3mm longer. This is due to the fact that a plastic gasket appeared in the case. The tightening torque of these bolts has not changed.
Since the plastic cover of the solenoid block is no longer used and there is only one gasket between the body of the solenoid block and the gearbox housing, the design of this gasket has been changed (Fig. 12).
The new plastic gasket is not interchangeable with the old one. A gasket mismatch with this solenoid block modification will result in severe leaks and low pressure in the friction control boosters (figs. 13a and 13b).
When installing a new solenoid block on 1998 and earlier models, the pins must be reinstalled to center the solenoid block on the transmission case. All three of the dowel pins on the new solenoid assembly should protrude 6mm from the bottom of the case (fig. 14).
In conclusion, the following should be noted.
The new solenoid block provides better gear shifting, so it can be recommended when repairing automatic transmissions to replace old solenoid blocks with new ones. They are less noisy and more reliable in operation. The Chrysler part number for the new solenoid assembly is 5015646AB.
300M, Cirrus, Concorde, Grand Voyager, LHS, PT Cruiser, Pacifica, Sebring, Cirrus Coupe, Neon, Stratus, Town & Country, Voyager, Intrepid, 300M (CHRYSLER Cyrus, Concorde, Grand Voyager, LHS, PT Cruiser, Pacifica, Sebring, Cyrus Coupe, Voyager) DODGE Caravan, Grand Caravan, Intrepid, Neon, Stratus (DOJ Caravan, Grand Caravan, Intrepid, Neon, Stratus) PLYMOUTH Acclaim, Breeze, Caravella, Grand Voyager, Neon, Voyager (PLYMOUTH Aklime, Breeze, Caravel, Grand Voyager, Neon, Voyager)
All of the above vehicles were equipped with two types of automatic transmission 31TH (A670), 41TE (A604) and its variant for a longitudinally mounted engine with front-wheel drive 42LE (A606) and 42RLE with rear-wheel drive or four-wheel drive:
1. Repair of automatic transmission Chrysler type 31TN Three-speed automatic transmission with hydraulic control and one solenoid, including the torque converter lockup. One of the most inexpensive Chrysler automatic transmissions to maintain and repair. Produced until 2001 inclusive.
This gearbox does not have pronounced “sores”, almost all automatic transmission components break down and wear out. Especially 31TH (as well as 41TE ) does not like slipping in snow or mud, since the differential lubrication system is not designed for this. In winter, they often turn to a car service because of the damaged case of this automatic transmission. The cause of damage to the body is as follows: with active slippage, thermal sticking of the differential pin to the satellite occurs; breaks the cotter pin that secures the pin in the differential case. Under the influence of centrifugal forces, the finger, when moving, leaves the differential housing and breaks through the automatic transmission housing. If you're lucky and your finger hasn't fallen out of the diff case, it will just cut through it. The chips get into the oil, damage the rubber seals, then the clutches burn out.
The second of the problems of this box is damage to the torque converter. Damper springs break, fragments damage turbine and pump blades, some of them with oil enter the pump and clog the oil lubrication channels.Also, the torque converter lock-up clutch often wears out or falls off.
Often, over time, the splines of the clutches of the FORWARD package are cut off. Initial symptoms - the car twitches when starting to move. In the end, the automatic transmission stops loading on the Driver and moving forward.
If only the reverse gear is missing, then most likely there is a problem with the brake band (Reverse band ) or the piston is defective Servo . In any case, a complete repair of the automatic transmission is required.
the planetary gearbox (consisting of 2 planetaries and the 1st sun gear) is rather weak for this automatic transmission and with a run of 100 tons or more begins to crumble and eventually completely falls apart, jamming the automatic transmission.
2. Automatic transmission type 41TE (A604)
Four-speed automatic transmission with electronic control. It is still produced today with minor variations. Automatic transmission 41TE - the box is quite unique and advanced. It does not have a single brake band, not a single one-way clutch (overrunning clutch - Overrun clutch ). Only two planetary gears and 5 clutch packs. The solenoid valves are grouped in a single block located outside the transmission. Due to this, the hydroblock is simple and reliable.
The old box name is A604, the new one is 41TE. This is a 4-speed automatic transmission for front-wheel drive Chrysler, Dodge, Plymouth and some Mitsibishi models. It has been produced since 1989, originally equipped with a transverse Chrysler 3.3L engine. A604 was a powerful breakthrough in the field of control of automatic gear shifts in modern cars. It was the first to use adaptive control of the gearshift mode, that is, the automatic transmission computer is able to optimize the shift mode, depending on external conditions and the driving style of the car. The box turned out to be quite compact and versatile. Her variation 42LE (A606) used on cars with a longitudinal engine (Chrysler Concord, Eagle Vision, Dodge Intrepid, LHS, 300C) and 42RLE with rear wheel drive.
five packs of friction clutches (Underdrive, Overdrive, Lowrevers, 2-4 clutch, Revers clutch );
four hydraulic accumulators;
two planetary gearboxes;
hydraulic pump;
valve body;
block of solenoids (4pcs) assembled with pressure sensors (3pcs);
built-in differential;
2x electromagnetic speed sensors.
The automatic transmission service life declared by the manufacturer is 300,000 km, in practice, breakdowns occur already at 70,000 km. Among the shortcomings noted are:
1. Wear of the spline connection and the axes of the satellites of the planetary gearbox Front Planet ;
2. Spline wear Overdrive & Reverse Clutch Hub;
3. Release boxes after 2001 are equipped with torque converters with a modified design. Unfortunately, less reliable than the former ones;
The damper springs come out of standing, the locking clutch crumbles, which leads to a malfunction of the pump and bearings in the torque converter (screeching when the selector is turned to the position R or D, and also the chips clog the lubrication channel of the planetary gear set, which in turn leads to a FATAL failure of the automatic transmission. It rotates the bearing of the rear planetary gear set in the housing; with such a breakdown, the automatic transmission cannot be repaired. To prevent such a breakdown, it is recommended not to operate the automatic transmission with any transmission errors. especially with P0740 - there is a slipping of the torque converter lock, which means it has already flown off and at any moment can disable the automatic transmission.
5. As with 31TH, the differential pin sticks to the satellite with frequent and long slips of the 1st wheel, which leads to damage to the automatic transmission housing.
6. Approximately 10% of those who applied for repair rotate the bearing cage in the automatic transmission housing. The reason is the lubrication channel of the rear planetary gear bearing clogged with the torque converter blocking.With such a breakdown, the automatic transmission cannot be repaired.
7. Oil and filter change period 25,000 km - 50,000 km. Use ATF+4 oil recommended by the manufacturer;
8. They often turn to service stations with the problem of oil splashing through the automatic transmission dipstick or through the breather. The reasons are oil overflow above the level, a clogged breather, overheating of the automatic transmission, especially in summer in traffic jams or when driving with overload (trailer, 7 passengers, driving in the mountains). Clean the breather, do not pour oil above the level, install an additional radiator to cool the automatic transmission, clean the cells of the air conditioner radiator since the automatic transmission radiator is behind it and does not receive air cooling, ensure the main radiator cooling fans work properly.
With frequent transitions to emergency mode, the presence of error codes associated with automatic transmission malfunctions (P0700) you can read it yourself 3 times on / off the ignition key, the smell of burning oil, the color of the oil is black, noises, squeals from the automatic transmission, the presence of a large amount of chips in the automatic transmission pan when changing the oil - Load the car on a tow truck and take it to a competent Chrysler automatic transmission repair station. Towing on a rope, or even more so moving under its own power, can significantly increase the cost of repairs.
Repair of any automatic transmission from 1 day
CVTs, DSG, torque converters, new and remanufactured automatic transmissions, spare parts
Well, here it is clear what the conversation is about.

Sorry for the link to another site, but there is a lot of information on automatic transmission https://my.housecope.com/wp-content/uploads/ext/64/
Thank you, there is my topic on that site))))
first, the pressure in the ports is measured, on a running car .. then with a probability of 80%, you can determine where and why to climb ..
Here's where I can find out the purpose of these ports, in what mode in which port and what pressure should be.
specify the data on the car, year and engine .. I will throw the pressure parameters ..

let's go in order, without nerves, what is happening with korobas now?
Thank you for your participation and understanding)))
Today, if I gather my courage, I will finish collecting it and stick it back.
How do you check the automatic transmission without a troubleshooting card and then?
I work at the service station myself, but as an electrician, so I removed the box, sorted it out, replaced everything that was criminal and assembled and installed it back.
Don't worry, you can't avoid another withdrawal. ))) only already for troubleshooting ..)
if you haven't started assembling yet, check the trim at the very bottom of the box..

I'm not worried, I've calmed down a little already, time heals, even nerves)))) How does it look and how to check?
Let's continue the topic of reviews of all sorts of automotive things 🙂 Today I want to tell you about ordering a very extraordinary product - a solenoid block for an automatic transmission. We are all used to ordering various gadgets, toys or clothes online, and we almost forgot that eBay is a storehouse of rare and expensive (at least in our country) goods.
My brother owns an American car, a 2002 Dodge Intrepid. The car suits him with everything and he is not going to change it in the foreseeable future. Moreover, now there are no special problems with spare parts for the "Americans". True, if this does not apply to any specific part, for example, an element of an automatic transmission.
It just so happened that, despite all its reliability, automatic transmissions in cars began to die. At first, this manifested itself in a “slowed down” change of regimes, then in kicks. You can ride, but not comfortable. Therefore, the question arose about the repair. After a couple of diagnostics and based on my own experience, it was decided to change the block of solenoids. Of course, one could try using a repair kit, but no one can guarantee that such a repair will last for a long time. Therefore, we were puzzled by the search for a block. Having studied local offers, we came to the conclusion that no one will sell the unit separately from the automatic transmission. And if someone sells, then its cost will be around 90% of the cost of automatic transmission. And if the car is American, then where to look for such things, if not on eBay? As it turned out, this stuff is in bulk there, and at a price of $40-45 (excluding delivery).
After payment, the parcel was sent the next day, all information on its tracking is available here. It took her less than 2 weeks to get from the USA to Belarus (the last trackless trip from China took 3 months).
The seller must be commended. The parcel was well packed: a cardboard box, a roll of bubble wrap, a couple of newspapers. All this ensured the safety of the goods during shipment. True, by and large, there is nothing special to break there 🙂
The block of solenoids was used, but restored by the factory method. This is indicated in the ad, the same can be seen in the appearance of the product:
I think a small digression on the topic of what a solenoid block is and why it is needed will not hurt here: “The solenoid block is used to control an automatic transmission by means of solenoid valves (solenoids) assembled in one common block. Modern solenoids work in such a way that they are able to control the bandwidth of the channel within a fraction of a second, thereby allowing the clutches to move and change the transmission characteristics of the automatic transmission. Thus, the solenoids are responsible for shifting gears, blocking the torque converter (donut) and adjusting the pressure in the automatic transmission hydraulic control system.
The block is original, has the designation 4539749. Next to the code there is an old Chrysler badge of the 2008 model, that is, it is logical to assume that it was released later than the car in which it will be installed.
Inspection of the insides showed that everything is fine there. All springs and rubber bands are in place, everything is clean and tidy. It is impossible to check the solenoids themselves before installing the unit in an automatic transmission in garage conditions, so it remained to rely only on the honesty of the seller.
The solenoid block is installed inside the automatic transmission. In order to get to it, you need to remove the pan and hydraulic plate. The lesson is not that difficult, but it is best to do it on a lift. We were engaged in this sacrament in the pit, and even in winter ... Therefore, the procedure dragged on, and since all hands were in oil, there were not many photographs of the process.
Trying on a new part before final installation:
As a conclusion, despite the fact that we overwhelmingly associate trading platforms as places to purchase all sorts of electronic gadgets, we should not forget that these are, first of all, stores selling rare items. Stores that allow you not only to save money, but also to buy something that, if not impossible, then very problematic to find offline.
On this, perhaps, everything. Thank you for your attention and your time.

P.S. A little about the 42LE box and about the problem with the solenoids block.
