#1769 of 2067 Transmission Problems
May 16, 2009 (2:49 pm)
I have a 2001 Chrysler Town & Country Minivan. The transnmission just quit shifting. I had the codes read and the following codes were found:
BBECM internal fault
BBECH unable to communicate on the SPI line
BBl.- Shorted input sensor
BB2.- Shorted electrical circuit
BB3.- Failed ECH
BBTCM ROM fault
BBECM detected a ROM self test failure uithin the rCM
331.- Shorted solenoid or sensor within transnission
632.- Shorted electrical circuit
BB3.- Failed TCM
BBTransaxle control system fauIt
BBECM received a signal that the transaxle control
BBmodule has a fault
BB1,- Shorted or open circuit uithin transaxle
BB2.- Failure of transaxle control nodule
Who Can help me? Is it the wiring, the TCM, a Solenoid, a speed sensor .....?

Replies on this thread are seriously petering out, so I thought I would say something. Whether or not it is of any help... I am no kind of mechanic, but I did recently have my tranny rebuilt by Dodge for all the same problem as you and everybody else in this forum have had. Phrases like "internal fault" and "within transaxle" very much suggest to me that you are looking at a full transmission rebuild. I was lucky enough to have been just shy of my extended warranty running out, so I don't know what it would have cost - but I think you are looking at at least 2000 bucks and perhaps more. On a 2001 you are stuck, because if you sell the car to someone with a bad transmission you will get nothing for it. And it is probably only worth what it will cost to have the problem fixed. If the van is otherwise in good shape, I guess you have to suck it up and have it done and drive it until it dies (again). That's probably what I'd do. At least you can be mostly assured that you won't have to deal with transmission issues on this van ever again! So I guess this counts as moral, rather than technical, support. Good luck!

What heppens if your currently dealership closes and you have to drive to the next town, like the current problems? You will probaby need Mr. Transmission or AAMCO to fix it as it seems, like in the case of the couple that purchased a 1996, , Chysler service does not seem to be interested;

OK, I'll make a wag at this. All of what follows is based on experience as an Electrical Engineer, and not any specify automatic tranny experience.
1. P0601, BBECH unable to communicate on the SPI line . SPI stands for Serial Peripheral Interface, and is a low cost, simple way for a computer to communicate with some external device. In this case, the external device is probably a sensor associated with the transmission. So the fault code means that either the sensor itself has failed or the interface to the sensor has failed (broken wire?).
2. P0605, BBECM detected a ROM self test failure uithin the rCM. A ROM is a Read Only Memory that is part of of a computer/microprocessor board. Many computer systems have some sort of self test on the contents of the ROM at power turn on (checksumming, CRC, etc). According to the diagnostic code, the electronics module failed this self test.
3. P0700 BBECM received a signal that the transaxle control BBmodule has a fault. The BBECM (maybe considered a master control unit) detected a fault in the transaxle control unit (one of the slave units???). A faulty transaxle control unit is consistent with the first two error codes.
If I were going to do anything, I would start with the cheapest, simplest thing to replace and see if that fixes the problem or changes anything. That would be whatever sensor it was that would cause the original P0601 fault.

#1774 of 2067 Chrysler Voyager: How know when need new transmission? Stranded?
Jun 02, 2009 (6:00 am)
Our transmission for our Chrysler Mini-Van doesn't "feel right." Like it's in the early stages of slipping, but if we drive it gently we've had no problems for about four months.
How do you know when you need a new transmission?
We want to drive it to/from the beach this weekend (four hours each way)... what is the likelihood it would leave us stranded? Like I said, we noticed a change 4-6 months ago but it doesn't "feel" like it's going to fail immediately. One mechanic said "these transmissions go fast when they start to go out" but that (so far!) hasn't been the case with us.
A new transmission is $4K I hear... or $2K for re-built and we've just been waiting for the right time to plunk down the dough.

Have a problem with engine stalling when engine gets to operating temperture.
This has started happing as the weather got hot and humid. You can put in neutral
start and tromp the excellator it stalls as if not enough gas getting through.
could this be the fuel filter? or fuel pump? Have 14,000 miles on sparkplugs.
Have recently put new water pump and timing chain in van.
Will appreciate any help with this.

Have you checked the computer for any stored diagnostic codes? It sounds like it could be either the air temperature sensor or map sensor. They are an easy place to start. If you do not have a code reader or know how to get them with the key method, you can go to any autozone store and they will check for codes for you. If the check engine light is not staying on, it could be an intermittent code.

This could be a number of problems so getting codes read is the first step for sure.
The tps (throttle position sensor) or air idle motor are 2 common causes as they are moving parts and wear out or get sticky.
Does it idle smooth or rough?
If it nice and smooth then that should rule out a vacuum leak.

Many years ago we had a 91 Caravan that had a stalling problem. As I recall, the fuel injectors needed a cleaning; after the fuel injection service it ran fine. Good luck.
