Hey guys,
Long time no posts but, I have a question.
My tranny failed. I lost 2nd and 4th. I had it rebuilt and added a few upgrades like a beast sun shell and a Transgo HD2 shift kit.
Now I have an issue with the TC locking up on partial throttle at 35MPH. The truck rumbles like a vehicle thats been shifted too soon. The tranny guys stated that the TCM controls shifts and lock ups. My U7193 allows for shift adjustments but only for WOT.
Is there a way to adjust part throttle shift points to stop the truck from going into 4th OD at 35MPH? I'd like it to not go to 4th until at least 45MPH.
Thanks!!
WB
