Hi everyone,
I feel some vibrations between 1000 and 1800rpm whatever the speed and I suspect the torque converter on the 42RLE.
I saw that ATS proposes an improved transmission or some pieces to improve the stock transmission (torque converter, valve body modified and CoPilot)

I would like to have your advices about that. Is it makes sense to improve or replace the 42RLE or to swap on another transmission ?

Thanks for your help

Vibrations from the torque converter were addressed back in the 2009 time frame. See if your JK has had the computer flash that was used to fix it. The dealer should be able to look at your JK's history.
