Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

 

That could be an internal valve problem, however, you may want to try the input speed sensor, as there has been a service bulletin on them with an updated part. Here is what it states.

i just noticed you got paid twice . so what is the proeedure for removing the valve body. i removed the bolts but it did not come completely loose. i could not see what was holding it
Expert:  Jerry replied 5 years ago.

I don't know about the got paid twice thing, I see $23 on this end. The valve body should come right out. Let me give you the steps that I have.

Expert:  Jerry replied 5 years ago.

That's all the information that I have on it. Let me opt out and we can relist the case to see if there may be another expert who may have more about it. Thank you for your patience.

Customer: replied 5 years ago.
it looks like i have a diferent tranmission. the servi ce letter about the speed sensor could not apply to me because i got the(NNN) NNN-NNNNsensor and it fell in the hole. the body was smaller than the 879 that was in it. i relaced it with a new 400879 but the problem still exists. this is a1996 chrysler town and country .
Expert:  ricardo hohl replied 5 years ago.
hi there i will like to help you lest start with this ,if you are just replacing a speed sensor why is the valve body coming out?, when the speed sensor is outside.
Customer: replied 5 years ago.
the scan tool said it was either a stuck valve or the speed sensor from the code. the speed sensor did not cure the problem.all the info i recieved before was useless, it was about the 3 speed. i hav e a 4 speed. i was told the valve body and the shift shaft come out together, the nut and lever must be removed from the top to let it drop out the bottom.now i hear a click and sqeel about20 mph when starting from a stop.but the trans shifts normaly after that until i slow to 20mph then abump shift into 2 and it wont shift again without turning the ignition off and on again
Expert:  ricardo hohl replied 5 years ago.
the click that you here has to be the transmission side mount its probably loose and needs to be tight,or the front mount if is a 4 speed and you feel a bump coming to a stop and then it limps is because a speed sensor is loosing signal have you scan the computer to see wish one is the one is it input or output speed sensor?
Customer: replied 5 years ago.
i did not know there was a input and out put. the info i got was sensor on the left front. iordered an 878 but it would not fit. so i returned it. as it was smaller than the one i had info on. i did rerplace one #879 it did nothing to help.i'm sure the mounts are tight as i had the trans out to replace the converter and front pump
Expert:  ricardo hohl replied 5 years ago.
yes there are 2 speed sensors.here this tsb will explain b
