I got my Trans back in my truck last week and the converter is Locking up again. The problem is it will jump between 2000 and 2300 rpm at about 70. Converter is a new 2500 Circle D. Any Ideas?

Valve body leak, cracked TCC solenoid...or maybe another issue.
Is this hard on the trans?
A converter looks thousands of times in it's life, it won't hurt anything, but if it stays unlocked and you travel a long distance, the trans might heat up if you dont have a good coolerQuote:

If I hold the gas steady, it will stay locked up fine unless I go up a hill. If I put it on cruise it locks in and out.
Should not be anywhere near 200 slip speed at 100% duty cycle on the TCC. Should be more like 12 or 8 or 23 or something low. 700 is completely unlocked.
When its working it is at 0 but when it unlocks it goes to 200 and then back to 0
Any Ideas?
So you commanded the PCM to keep it locked and the status light stayed GREEN or ON or ENGage and it still unlocked?
It will lock but will unlock after a little bit. Im going to try it again later on.Quote:

r u sure its locking and unlocking and its not just the stator locking from the converter because mine does the same thing but mine has a fairly loose stator
I guess I dont understand what your saying...lol :doofus:Quote:

If it has a tight stator its going to almost want to push the car before it gets to the stall. also if your stator is loose it will want to try to engage and disengage when the motor is right around the stall point. Like mine is a 2600 and at 65-70 mph its turning about 2400-2500 rpm so it essentially thinks that i am trying to brake stall it so its engaging then once it get below the stall point it disegages

He is what it is doing. Sorry for the bad quality.
