Just wondering i installed a 10" Ultra Performance 3000 stall with 12" lock up housing. The truck launches perfect it even burns rubber coming out of the hole. Now here comes my question my truck use to launch very crapy but had a very good WOT transmission use to shift hard very nice. Now the truck launches all some but the WOT is not the same transmission shifts week and the truck feels slow at high speed. Any one have a clue what can it be?
THANKS.
