My business partner and I both have 07.5 dodge trucks (6.7&AT) and have experienced "jerking" from the drive train when driving around town. We're not towing anything when this happens and it only seems to do it when I'm driving mellow... Could the TC be locking and unlocking causing the jerking? I searched the threads but couldn't find anything on this issue. Has anyone else seen this with their trucks?

Thanks,

Dan

 

How bad is the jerk? Mine does this but its only sometimes when I let off the gas(or diesel) and then apply light throttle.

 

Thats exactly when mine does it. It only happens when I'm driving it easy. Is there a fix for this?

The exhaust brake seems to affect the transmission trying to hold back. If you are just at the right speed it will try to hold back but then you fall below the speed threshold and it lets go. Its very quick too. Worse in T/H mode.
