Josh @ JS Performance -->

Just had mine rebuilt at Von Kattengell transmission in Eatontown. Installed the Transgo HD2 shift kit and used all performance/ heavy duty stuff inside. I took the trans out and brought it to him to save a couple bucks. He also has a converter guy that can build you a converter if you want. 2nd trans he did for me. 2 diffrent cars no issues yet.

Stay away from performabuilt haha, if you want a hd2 shift kit i have one for sale.

Second for JS Performance. Josh does great work
