Its a 96 4x4..... So its been jumping in and out of lockup... I did the brake switch, TPS sensor, and also got the noise isulator wire from BD Diesel and its still jumping in and out. I cleaned some grounds and powers but i dont know what else to do... It seems to do more often and worse on hotter days.. Sometimes it wont do it at all on a cool night. Trannys running at 140 to 160 degrees and fluid is full. Thanks

 

i would check your trans temp sensor. If its bad it will make it lock and unlock

 

Does anybody know where them tranny temp sensor is on a 96?

 

did u adjust the brake switch? double check and re-adjust...takes 3 seconds

if ur still having trouble I would install the lock-up switch so that u can ride home on the interstate in peace

 

I tried the lockup switch but my truck falls right in the years where i need a reflash for it to work

 

I've found that many times you just have to bite the bullet and replace the TPS

 

Yea man i bit the bullet and replaced the tps today and i still have the problem. New TPS didnt do anything.

 

What does the tranny relay do?

 

anybody have any other ideas???

 

did u install the TPS yourself? if not then obviously take it back to the guys that installed it...if u did it yourself then do a search on TPS adjustment...it is adjustable

 

Also check the brake sw.
The temp sensor is in the hot line going to the cooler , drivers side .
