Just like the title says.... Any suggestions on breaking in a performance transmission? ie... take it easy, don't go past 1/2 throttle and drive in a lot of stop and go areas? No WOT for a couple hundred miles? Drop oil after so much miles? Any help would be greatly appreciated....:thumbsup:

DTT told me to run Dex/Merc III for a thousand miles and then switch to a real good fluid. I'm about 1200 on some cheap Coastal from Autozone and about to refill it all with Amsoil.

Not that you need it right away(sooner the better), but an inline filter on the way back from the cooler would be my next mod.. Debris really flies around the first hundred mile though,if you pull the valve body, you'll see it starting pile up already. Pan filters can stop rocks, but that's about it.
