Ok so still yet to find a fix for my 4th gear or tc shutter as some one may know it on a 2002 47re, if anyone has any ideas here is a list of every thing ive tried.

Wraped ground wire "blk/org" in aluminum tape, replaced both batteries, replaced alternator, check and cleaned every ground, tried noise filter, tried both suncoast and ats fix and reset the apps numerous amounts of times.

Any other ideas to try would be great. Thanks nathan

Lubeguard "Dr Transmission, Shudder Stop" then start planning on a rebuild or swap.

Did you clean the PCM ground wire? That is the module that control the transmission.

Does it shutter through certain speeds as you accelerate? If so you more than likely burnt the TC and it will have to be replaced. Also if you fill in your signature it will help us to help you.
