Waiting on the arrivial of the Yank PT4000 converter but need to have trans rebuilt. Looking for recommendation on rebuild kit and will there be a need for a shift kit because of the stall.

Goal is for 11 sec. with bolt ons. Been able to get best of 12.39 @ 111mph (1.84-60ft) with Hooker lt's / y-pipe, SLP 2OTL exhaust, FTRA, KN/Lid, 160stat., ASP crank pulley, TR55's, 3.73's, Nitto 555 (not there drag radial)

 

Anyone have any info. Need to find out what I need to beef up the trans as its started to slip on 2 to 3 shifts.
