Just installed a rebuilt jasper 68rfe into my 15 2500. I also installed a new triple disc billet converter. Now truck stalls when put into drive. Works fine in reverse. Any help would be greatly appreciated. Thanks

Considering this started happening after tranny replacement, two likely possibilities I can think of: (1) torque converter stall speed set too low or (2) Torque converter not unlocking.
