I put my gxp in the transmission shop today it was slipping and plan to mod heavy any way so it's getting built right with a custom shift kit! What's the best trans cooler to get? And anything else I should have them do while they have it tore apart motor car has high mileage?

This ^. Give David a call @TEP and he will listen to what you want to do and put a package together for you.

I only lost by a half a car to a 2011 challenger r/t will the shift kit help enough and the freshly rebuilt tranny make me be able to beat him?

If I was losing by a half to a challenger I would have side swapped him.

My gxp is bone stock no mods at all not even CAI

If you upgrade the gearing to 3.29 on the new trans and add the shift kit, I would think the results would be better. I have yet to lose to a non - SRT chally.

Race a r/t from a 40 roll you'll have you're first loss
