yeah i built the trans i have lost 2nd gear twice, i got a bigger trans cooler also, the throttle body spacer is a waste of money, get a bigger cam with a different LSA like 112, and if you do anything to the rear end then put a detroit truetrac in it. Also i gave you the wrong number to my shop it 972-276-4800. I wrecked my truck this morning hit a patch of ice and samshed the front spun around and smashed the back i will have pics later
