I still would have gone 4l80e any day over TH-400
For a mostly track driven car? I would agree if I wanted OD, or intended to mostly street drive the car, but I got a TH400 for the lower cost, smaller size, and lighter weight, tons of spare parts available, and no wiring necessary (save for the brake). I would have gone PG, but I wanted to occasionally drive it on the street to local shows.
Where did you get the gold heat reflector? I need!
Pegasus racing carries it.
