Probably. It's not going to make as much of a difference as you're hoping though. I used to run an ATX and it just sucks period. I installed the shift kit, tranny cooler, high stall torque converter, and the thing burned up in less than 6 months. The only mod I've heard good news with is the stratus final drive gear.

It might be worth considering a swap to a MTX in the future and you'll wonder why you didn't do that to begin with instead of dumping money into an ATX that's only going to hold you back.

Others may have different opinions, but that is mine on the auto tranny.
