Torque Converter seems odd

I've noticed since buying my used 97 ZJ that when I let off the gas at crushing speeds it seems to disengage the torque converter. It doesn't happen every time but most of the time. Occasionally when going down a hill on the interstate it will also do this. Is this normal?

Are you checking trans fluid in neutral or park? An older trans that's being run a quart low from being checked in park can act similar.

good luck

Yes, any time you let off the gas the TC will unlock.

^ this, all your feeling is the unlocking of the TC. You only have problems if it doesn't lock once you continue cruising above 45 mph.

If at first you don't succeed, use more speed.

Normal. My 97 does the same. I will also add, use ATF+4 if you ever add any fluid. I used dexron III when I first bought mine just to top it off and it caused the shifts to be harder and I started getting a slight bump into tc lockup. Took off the pan, changed the filter while I was in there, added a drain plug, filled up with ATF+4 and it's back to shifting smooth as silk again.

Normal operation of the TC. Now when it starts to do the opposite, and not unlock when you let off the gas(causes the engine to slow you down) thats when there is cause for alarm.

Thanks guys. I had a tech at Aamco telling me that it was about to go. I knew he was scamming me. The tranny feels fine and I was confident until he said that. The tranny fluid has been changed every 40000 since it was new. And I just did it again at 100000.... It truly is babied and well taken care of.

Again, Thank You!!!!
