I have a early model '94 tbird and have torque converter shudder, I have read that the torque converter was up dated in the late 94 and 95 cars. Im planning on replacing torque converter and doing the jmod but have heard the '94-95 trans are junk. Should I put some sonnax parts in when I do jmod or not bother wasting the money on this trans. Other than the shudder in 3rd-4th the trans shifts fine. I have refilled with merc v and added a trans cooler already. The car has approx 120k on it. Thanks for input.
