Hey, just did a 6.2 swap from 5.3 in my 2012 Yukon. The car drove very smooth before with the stock stall. I figured the Zl1 stall would also be just as smooth part throttle, but the car shudders a bit with heavier throttle, almost like a very slight bucking. Am I just trying to lock it at too low an rpm? Seems ok above 2000 RPMS.
Do I need to change anything with the TCC slip or pressures?
