Hey guys, have any of you guys had a problem with the trailblazer that when you go from a stop to WOT the speedometer doest work stays at 0mph and when you let go of the gas it suddenly reads? driving normal works fine. i just added a stall converter... could this get fixed with tuning? Thanks..

There is no fix as of yet and I dont think HPT will be able to touch it.

This is what happens with a stall on the TBSS. It apears the input vs output shafts get out of the normal range and get lost. As soon as you let off it reads. As you found out.

Welcome to the world of the stall on this truck.
