My 01 TL with 300k with original tranny has been great but has some problems. Shifts fine when driven normally but when I need to floor it when it's shifting it jerks, still shifts but doesn't seem normal. Changed the tranny fluid not too long ago. I bought some Lucas transmission fix and was wondering how I put it in. Can anyone explain if the Lucas tranny fix is good/bad for the car, and how to put the fluid on the car. Thanks!!

 

300,000 miles. Nice.

Normally wouldn't recommend any additives to your car except for seafoam. At that mileage and the tranny sounds like it's kicking a little go ahead and add the Lucas it won't hurt it at all.

Come back and tell us if anything happened.
