Hmmm hey look i got a pdf about the seats... seems i was right... they can be verified via CAN, looks like it can be from the switch or module configuration Power Seat Switch - Vehicles may be equipped with a driver side eight-way power seat switch. The power seat switches are paddle-type levers mounted on the outboard seat side shields. Movement of the seat cushions and backs mimics the action of the switch paddles. MEMORY SEAT SYSTEM An electronic memory seat system is available on certain models. The memory system is able to store and recall all driver side power seat positions, outside mirror positions and power adjustable pedal position. The system can be set for two different drivers. On vehicles with a factory installed radio connected to the Controller Area Network (CAN) data bus network, the memory system is also able to store and recall up to twelve radio station presets (six AM and six FM), for two drivers. The memory system will also store and recall the last station listened to for each driver, even if it is not one of the twelve preset stations. The memory system will automatically recall all of these settings when a button of the memory switch is depressed, or when the doors are unlocked using the Remote Keyless Entry (RKE) transmitter (if enabled). If the vehicle has more than two drivers the RKE transmitter recall of memory features can be disabled. This is a customer programmable feature of the Electronic Vehicle Information Center (EVIC) set through the use of the appropriate steering wheel switches. Refer to Electrical - Message Systems/Message Center/CENTER, Electronic Vehicle Information - Operation for additional information on the customer programmable features. The memory system also has an "Easy Entry and /Exit" feature that provides the driver with more room to enter or exit the vehicle. When the seat is in a memorized position, it will move rearward 55 millimeters or to the end of its travel, whichever occurs first, when the key is removed from the ignition switch lock cylinder. This is also a customer programmable feature of the Electronic Vehicle Information Center (EVIC) set through the use of the appropriate steering wheel switches. The memory system also has a "Tilt in Reverse" feature that tilts the outside mirrors down a fixed, incremental angle when the vehicle is shifted into REVERSE with the ignition switch in the RUN position. This feature provides the customer with a better view of the ground and vehicle in the area of the rear tires when backing up. OPERATION POWER SEAT SYSTEM The power seat system receives battery current through a fuse in the Totally Integrated Power Module (TIPM) so that the power seats remain operational, regardless of the ignition switch position. When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat switch contacts to the appropriate motor or motors. The motor and drive unit operate to move the seat in the selected direction until the switch is released, or until the travel limit of the power seat track is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through the switch contacts. This causes the motor to run in the opposite direction. MEMORY SEAT SYSTEM The Memory Seat Module (MSM) receives battery current through a circuit breaker in the Totally Integrated 2009 Dodge Grand Caravan SE 2009 ACCESSORIES AND EQUIPMENT Power Seats, Front - Service Information - Grand Caravan, Town & Country steve Monday, May 23, 2011 2:14:04 PM Page 5 © 2006 Mitchell Repair Information Company, LLC. Power Module (TIPM) so that the power seats remain operational, regardless of the ignition switch position. When the driver memory seat switch control knob is actuated, a resistance signal is sent to the MSM via the Controller Area Network (CAN) bus circuit. The MSM is responsible for the 12V battery feed and ground path to the power seat adjuster motor. The adjuster motor operates to move the power seat adjuster mechanism through its drive unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached. The MSM receives memory set/position switch input through the CAN bus circuit. The MSM also receives hard wired input from the hall effect sensors, mounted on each of the driver power seat adjuster motors and the driver side view mirror motor. The programmed software in the module allows it to know where the seat/mirror is located in its designed travel by a pulse count generated from the hall effect sensors. This way, when the memory switch is depressed the module will power the seat adjuster/mirror motors until the correct preset location is achieved. The module will prevent the seat memory recall function from being initiated, if the transmission gear selector lever is not in the Park position, or if the vehicle is moving. These inputs are monitored over the Controller Area Network (CAN) bus circuit by the MSM. I will e-mail it if you want... is a lot in that one... 38 pages but no schematic.

It might be something else like module setup settings adaption that i am not aware of. I have a version of alldata that covers town and contry and the dodge but as you say only covers petrol engines and not the voyager made for europe export, haynes book din not even bother to buy as is crap in my opinion, haynes pro database is not very helpfull either as covers specifics suitable for a garage that needs to replace stuff, the chrysler grand voyager dvd i have is the most complete but the wiring part is more wiring then a schematics database, which for me personally that if needed i can repair a pvb board at component level looks like child play. Is not schematic for the seat itsel, the wiring shows the wires going to the switches in the seat via plugs and thats it coming from a seat module. Obviously the modules has a power feed a ground and wires going to the seat but much more. At this moment in time i do not even know exactly where is located...not sure if module itself is corelated to other modules and comunicating with them and so on... witech probably could reveal more as far as i digged into it but even if i buy one is useless without acces to their global server network. Worse is we do not have where to get info. The town country except some parts is different from what we have in uk, yes we have the gearbox suspension and other bits core related but others were made specially for Europe.

P0740 on this gearbox is... TCC out of range, if other codes gearbox related are present is a electrical issue usually wiring or ground straps, if code is alone... gets complicated, can be the solenoid, the gearbox oil pump or torque converter. When in 2nd, 3rd, or 4th gear, the Torque Converter Clutch (TCC) can be locked or partially locked when certain conditions are met. The TCC piston is electronically modulated by increasing the duty cycle of the LR/TCC solenoid until the torque converter slip difference (difference between engine and turbine speed) is within 60 rpm...so when greater MIL is illuminated if is sliping to much... The lock is for fuel economy but also to signal the start of a mechanical failure...before it gets bad. Anyway leaving that aside...back to the seats... guess what i have the same issue... and the documentation that i have only includes schematics and how to remove seat and install... From the schematics i do not see any sensors only switches and a module? so seems i am not a lot of help... if wiring diagram would be any help to you let me know.

if is the switch to blame... i was right... is inside, you will need to get dirty... i have some pdf's for this gearbox if you pm a e-mail i will e-mail it over. I would eliminate all the simple parts(electrical parts) from above before getting complicated... if you are not mechanically minded and electronics minded is going to be difficult ... Hope this helps.

hello, this is going to be a looong post... P083B-LC PRESSURE SWITCH RATIONALITY Theory of Operation The Transmission system uses three pressure switches to monitor the fluid pressure in the L/R, LC, and OD elements. The pressure switches are continuously monitored for the correct states in each gear. The LC pressure switch monitors the fluid pressure to the LC clutch to confirm proper operation of the LC solenoid. If the LC pressure switch is identified as closed in P or N, the code will immediately be set and normal operation will be allowed for that given key start. If the problem is identified for 3 successive ignition cycles, the transmission will go into Limp-in mode. When Monitored:Whenever the engine is running. Set Condition:The DTC is set if one of the pressure switches are open or closed at the wrong time in a given gear. If the problem is identified for 3 successive key starts, the transmission will go into Limp-in mode and the MIL will turn on after 10 seconds of vehicle operation. Possible Causes RELATED TCM POWER INPUT DTCS PRESENT LOSS OF PRIME DTC PRESENT (T81) LC PRESSURE SIGNAL CIRCUIT OPEN (T81) LC PRESSURE SIGNAL CIRCUIT SHORT TO GROUND (T81) LC PRESSURE SIGNAL CIRCUIT SHORT TO VOLTAGE TRANSMISSION SOLENOID/TRS ASSEMBLY POWERTRAIN CONTROL MODULE

I will post here a list of the codes for that gearbox when i get home tonight, will take it from there, as on the side for the code i will have in the system the checking troubleshoot procedure for the code so probably you will be able to eliminate most of the causes yourself. Just had a look on my email where i have a layout of the solenoids and looks like that is located on the side of valve body not sure if is replaceable individually at this point but i will find out. Sorry for late reply but seems i do not get notifications via e-mail from this forum.

Are you sure about that B in the code? I only seen the post now, i will look up in the gearbox rebuild/workshop manual.

I will have a look at my one but is not back yet... that p0740 is pest... 2 weeks already... i have the schematics but to be fair it looks weird how they choosed to represent it... now thinking about it might have the same issue as i remember adjusting drivers seat first time... did not touch it sice tho...

Hy taffy, will try to dig out through what i have about the car in the workshop manual but i do not think is related to position sensor but the switch itself, i will have a look and see what i can find, actually i will check my car also as i always used the memory. And yes i know the feeling about geting a blank when it comes down to this model

Hello, the gearbox on that is ultradrive 62te. Do you have the transmission diagnostic codes? I can look them up for you in the chrysler workshop manual. Depending on which switch solenoid is at fault are part or not from the solenoid pack. When was oil and filter changed last in the transmission and was atf+4 used? All switches solenoids are inside the gearbox, except a few sensors. I can only assume from what you described so far that could be range switch related. If trans oil and filter was never changed or changed recently (with not confirmed type of transmission oil) this would be first call in adressing the issue. As a note, yes temperature sensor on the engine can create some funny behaviour in relation to transmission and was reported few times in other places. As long as no mechanical internal issue is involved should be a relative easy fix as transmision does not have to come off. The problem we have in uk tho is that are not many places that would fix a autobox, and fewer that will fix it without doing a full recondition.

I got the autel MD808pro uk. Straight from autel https://www.autel.uk/products/mid-range-tools/md808pro-uk-edition/ Cannot comment on how deep it goes but seems is not leaving any stone unturned as far i can tell... but again like someone stated in anether topic, not easy to get something better then keydance under 400£. I skipped launch as the only one that i could confirm it works was in the 4 digit price, and i am not talking about the ebay counterfit crap. For a normal person owner i am not sure that is justified in price even the autel md808 as many people do not understand live data and the functions. I am going to use the autel on other cars also so for me was justified.

1rpm? or 1k rpm? if first 100% still something wrong. As for diagnostic: the garage has to have at least a Launch X431 or a Autel MD808 or higher, and having someone that knows at what is looking is a bonus, very rare in my area at least...

good to hear that is fine, temp sensor seems that done it? i was looking today through the workshop manual and on this voyagers seems like also coolant sensor faulty gives also the same behaviour. Side note 250 Ohm is very high for the solenoids as far as i checked... maybe you miss spelled?

+1 on ATF+4 and cannot stress this enough... Disconnecting the battery on this voyagers clears event data and also dtc codes, and also puts the gearbox pcm/tcm (computer) into learning mode/adaptation mode, during the adaptation mode manifests in some hard/shudder in gear changes till this is finished... and this is according to chrysler workshop manual for 41te/42te/61te/62te gearboxes. As for ATF+4 i would only use the mopar one as is the genuine and is not more expensive then other atf+4 like valvoline and others... If gearbox is filled with dextron... is very bad for this transmissions... Garages ussually not stock atf+4 unless they work on this gearboxes often...

Transmision oil level is ok? Fluid and filter due service change in date? Battery disconnected recently? This are the most common causes for what you describe for 40/41TE transmission. Any DTC stored?

Hello, time to update this, I managed to read the codes in the end... Either Launch diagnostic will read this Chrysler properly or Autel diagnostics. As a side note seems to be a great deal of counterfeit Autel and Launch on ebay and amazon as they appear tempting as are less the half price. I spent a lot of time ordering stuff and returning it, and even finding a garage with the above diagnostics was hard as some have some old models not updated and are not better then my generic scanner or key dance. Anyway seems like i have stored P0740 and P0087.... and this codes are not shown by key dance... at this point i do not know if is a wiring issue or is more complicated.

Hello, flickering lights on the dash or lights as sidelight driving lights? As for the fuel presure regulator check ebay search... are plenty options for your model.

Does it smoke at all black smoke, if it is that would be unburnt diesel and personally i would check in the following order: intake system from air filter to turbo and further to intake, hoses tend to age develop cracks, the next port of call would be to check egr and intake throttle valve and last would be to get someone to read the maf sensor readings in regards to acceleration, as a incorect reading of the air sent to the engine would make the computer think it needs to put moore fuel in that needed. Bare in mind that a MAF sensor wont put a code up unless the ecu finds some very extreme readings.

A approximate full fluid change can be done but involves disconnecting the return oil line from the oil cooler, run the engine and top up in the same time as it gets out... til fluid on return clear, that will refresh the oil cooler and most of the torque converter. Is hard to explain and a bit of a mess to do it.

Is that measured mpg or displayed by car? is the water/coolant temp going up normally?

Ok, this what i sent to the seller: Hello, how this works, what it does not do? I assume it needs to be used with a laptop tablet, what are the requirements? Win vs ? 32? 64?. I am not planning to update but do i need to be disconected completly from the internet or is fine as long as i do not update? It connects to all crysler grand voyager rt/mk5? To see live data and status? I am askimg as curent tool cannot read all that is wrong, as some stuff are not displayed even by the built in car diagnostic. And the reply: Hey there, Thanks for your inquiry! To answer your questions: After you receive the parcel, install the software on your computer (windows 7, 32bit will be ok) After software installation is completed, send me your teamviewer id and password for us to activate it for you, then you can connect to car star test. You can choose to use the internet or fine, either option is fine...just make sure NOT TO UPDATE it by yourself. This device is not blocked or damaged by connecting to the internet. It can work with most Chrysler cars, but we can't guarantee it will work with ALL models. Please keep this in mind! Maybe i miss something but he cannot state that it works on my model... and about teamviewer part i do not agree. I will get the delphi one.

As i steated before my one is on the shelf, i choosed not to have it on. No i am not disposing of it or giving it away. In the interest of everyone around here would be still nice to know where to get one, what is matching etc...

I will update the topic, but seems to be the best option to read everything except a drb3 i found second hand for 900£, i will decide between this witech clone and delphi2015r3 price wise is not much of a difference. What i know none will be able to perform software updates and flashes but my purpose is to maintain and be able to repair any isues that apear. Past experience with other makes is it should that is worth... but never experienced so much lack of info like with this crysler... and stealerships... we all know how that goes... For now i asked the seller some questions i need answers to... if the answers to the questions match my expectations i will hit the buy button. My cheap diagnostic is based on the same chip as yours... and yes looks good enough for most things but seems like i stumbled on a issue is not that simple.

How did you checked torque out of curiosity? re step what you done when you changed the solenoid pack...
