Vans & Minivans Chrysler Town & Country/Dodge Grand Caravan Chrysler Minivan Transmission Problems

You are in the Chrysler Town & Country/Dodge Grand Caravan Forum. Your Host is Karens
I have a 1997 T&C 3.3 engine. The reverse will not work, and I am getting a trouble code says -Incorrect gear ratio2 and another code about the trans control unit. I Replaced the selonid pack, unpluged the trans computer, cleared codes and still no difference. I also changed fluid, with the atf4 fluid and new filter, I did not notice any fresh metal in the pan. It will start to drive a bit then just loses the drive, if I reset it it will start to drive again, but then lose out. But No reverse at all. Any help would be much appreciated.

There was no sign on the trans going out, just went out on my wife, in the middle of driving. Would another trans computer need to be flased?

Replying to: leadfoot69 (Jan 16, 2009 2:34 pm) The van has first and shifts into second. I can go as fast as i want - of course the RPM just climbs and I go faster in second gear. I have been afraid to red line because i do not want to make it worse - right now i can still drive to the Cottman Transmission store about a mile away. Right now there is no slipping. I just have reverse,first and second gear. The van was senior owned and garage kept so it looks new. At $3295.00 sold as is by Buhler Dodge Jeep this is disappointing. We do not have $1800.00 for a transmission (seems to be talk about repair price on the internet). Thanks for you help - will check later for your reply. |

I put a code reader into the terminal port. The code is PO-720-01. The manual book states it is the "Output Speed Sensor Circuit Malfunction". My next question is that the "TCM" computer I have been reading about ? I see that they are around $199.00 refurbished with a warranty. Look forward to your help. sonofadocker

Replying to: leadfoot69 (Jan 15, 2009 1:57 pm) I still do not know if it something that can resolved without having to rebuild my tranny or having to purchase a new one. I had the codes read from the TCM at a transmission specialist shop "non franchise" and did not like his instant diagnosis thereafter stating hat I will need a new or rebuilt tranny. He codes he pulled from the TCM I remember code:53 and there was another one between 51-55 so the second code was either a ,51,52,54 or 55 I do not remember sorry. Can you please tell me if just based on those two codes there can would he really be able to say I need another transmission or rebuild this one at 1800.00$ Thank you and forgive me for my incomplete posts but I really literally only know what I have learned around here when it comes to cars. Thanks in advance!

Replying to: roro121 (Jan 18, 2009 11:59 am) codes 50,51 is same thing as other codes but adds a couple other things that might be wrong aswell witch are input/output sensors or tcm failure.but other 3 codes are clutch slipping. 50 is reverse 51 is 1st 52 is 2nd 53 is 3rd 54 is od Any of these codes put tranny in limp mode witch then you only have second gear So i would have to say tranny is in need if rebiulding or replacing. if you want to go a cheaper for now route you can get a used one from local wreckin yard and put it in they ussally come with some warrenty 3months or something like that. 55 is end of codes Sorry there isn't any better news for you.good luck. |
