If you have done nothing to trans settings, then I would say you are exceeding max torque and you need to adjust torque managemant tables.

Definitely need to adjust the Trans for the added torque. If it helps, I have my copy of the tuning school 6L80E tuning guide. If you're running a stock Trans this will definitely help. I have a full mod transmission now so my copy doesn't apply for me anymore. It is still available and I will sell it for $60 shipped. It is the lastest version 3.0.0.

You need a good tune...Originally Posted by tricky1
Well if the engine isn't calibrated properly shifting will be all over. This meaning that if reported load is off due to improper MAF and VE cal, the trans doesn't how to properly calculate shift times and pressures.
