not to sure never had to change one but there usally in the back part of engine close to top of engine posible in the center head. when you pick up new sensor then you just match it up to one in that area.

I bought this van the other day. It has 158k on it. The test drive at the dealeship was done when the van was cold. It worked perfect. I drove around one mile ( it was snowing).
I bought the van and trailered it home.
Today when the license plates arrived I let the van run a long time outside ( 8 degrees outside). The first time driving the van at normal engine temperature - the transmission will not shift out of low.
I have reverse and low. No check engine lights are on.
The fluid is a nice bright red and filled to the full line.
The dealership - Buhler in Hazet, New Jersey will not assist in any repairs or refund.
Any adivse would be helpful as I have to sell one of my work trucks or cars to fix my wifes new/used mini van.

what motor and tranny are in this van?
and did you bring engine up to redline and stilled didn't shift?The reason i ask this is because these trannies will shift even if you have it in low on gear selector when approaching redline engine will make tranny shift that is if it has the 4 speed electronic tranny.and that could be an indication of a bad selector sensor or kick down cable stuck down.

1997 Town and country Transmission problem by cridez

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.

One of them is po700 trans control sys malfunction. And Po732-incorrect 2nd gear ratio
I thought about trying to get another trans computer at the local salvage yard, seems like it is stuck in limp mode. 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?

Code 700 is a code the ECM put up to tell you there are codes present in the TCM witch can only be pulled out buy a proper scan tool. as for 732 yes second gear ratio there are some test you can do but to long to list here for that.
Best to get codes pulled directly from TCM to help out in diagnoisis.but sounds like it proply one of the speed sensor but need codes to tell you or just replace them but could be a pump problem or valve body well there lots of pauseable causes. as for tcm from another vehicle you can but a reset or beak in presedure must be done or it could have suttering probs during lock up and same goes if replacing torque convertor and speedometer signal must be recalibrated aswell.

i went down and got both input and output sensors, still nothing. I guess I will try to get a trans computer in the morning and try that. How do I check that pin issue. I have noticed a lot of people have had a problem where a pin comes out not sure where thats located. Can this be checked by droping the trans pan.
Thanks for the input.

The motor has 3.3 stamp on the top. The transmission is a four speed i believe as there is no overdrive selection on the dash display.
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.
