Guys, since I'm probably fine tuning my ride on the single 76 turbo, boosting probably 12-15 psi, I want to Go to a monster 4L80E now, so when Allen TT it, wont go stall for a while.

Any Recomendation..Shops, Types, anything....?

BTW, befor u cricify me, I know my L5 4L60E won't even hold the 12-15psi for my current setup, but is all I got here, and I'm resing to toast it any way.

Also I haye the 4L80E, cause I had so many bad Xperiences with 4 2500 Suburbans with 350ci, every year have to repair them or build them up...just grow my resistance, but u all guys swear on this trannys almost religiusly, I have to fall for one....what will be the purpose to ask u, if not to learn of ur trials and errors!!!!!
