Well the sidemount blower is going in 2 weeks, i can't wait but I know its going to be slightly hard on the trans (not like the power of the Radix but its still going to be pushing 5psi, I estimate I'll have 330rwhp and maybe 360rwtq with my mods, maybe more, maybe less). Anyways I want to buy all the parts that I can and take my truck down to the local trans guy and have him install all the parts. Here's my plan to put in the 4L60E:
-Larger trans cooler(has stock towing trans cooler now)
-Billet servos(including overdrive servos / pretty much every servo you can
get).
-Billet accumulator piston
-valve body seperator plate
-better valve body
-shift kit

Thats all I can think of, what else should I throw in there? Whats the weakest parts of the 4L60E. My trans has 77K on it but it doesn't slip, Ive had the trans fluid and filter changed every 20k miles. Any suggestions would be greatly appreciated.. Thanks

 

The weakest part is the 60 I dont know what else, but if you are trying to build a bullet proff tranny, you may want a hardened input shaft too, all metal accumulators, I also have the Sonix (sp) pinless accumulator piston. You may want the check ball release too??
