hi there i am new on here and can not find what i am looking for, i have 97 ram 4x4 and the torque converter is locking and unlocking i replaced tps and still didnt help so any help would be great.


i also notice that when getting on the highway that it seems to lock up around 50 mph and i have to push the pedal pretty far for it to kick down.

 

Locking and unlocking is good. That is what is should do based on speed/load. If you have to push pedal pretty far to kick down there may be one of two issues.

It seems that throttle cable on these tends to stretch. Check above gas pedal to see if excess cable is hangin out. Then, go to the FAQ/DIY section and download the free service manual. Did I mention "FREE?" Look for the instructions to adjust the Throttle Valve Cable. It is on passenger side of throttle body and goes down to transmission. Check/repair/adjust these and you should take care of the problem.

ok thanks. but the tc is unlocking and locking while crusing at highyway speed

 

That is normal. The OD on these trucks combined with the 3.55 gears is not very good with holding speeds on an incline. Meant for cruising on mostly flat terrain. If I know I am coming up on a hill, I hit the OD button so it doesn't kick in and out of OD.

 

well i know its not overdrive cause i can turn off od and it stills jumps about 300 rpms than back down so i know its the tc but dont know what to do to fix it. every forum i read it talks about cummins and i dnt have a cummins so idk, ugh

 

Still sounds like a TPS issue...jumps 200 or 300 rpms quickly, whether using cruise or not.

 

right it jumps quickly than right back down. ill try to unplug it and plug it back in

 

Check trans fluid level also. Do it in Neutral and not in Park.

 

did that trans fluid is perfect lol

 

Have you gotten anywhere with your issue?? It sounds like my truck is having the same problem. I have changed the TPS but mine is also throwing a TCC code, P1740 I think if I remember correctly?? I canged the TCC solenois and also the trans output sensor. Does anyone have any other ideas on the problem other than a rebuild???
