It was perfect for 5 years and 30k miles and then I sent it to precision for a rebuild because clutches were worn and it's been shit since. I had some tranny issues that may have permanently hurt it. Transbrake was messed up and cooked it so had it rebuilt again and now it surges and sometimes after a rock solid shift to second there another engagement almost like another gear but it's just the convertor engaging.. Like 0-30 regular no boost acceleration it surges like letting out a clutch in a manual transmission. Surges from stop light take off and then surges after hitting 2nd. To be clear the shifts are firm and hard, it just after the shift or initial take off it surges and then engages.
