Is this what is referred to as "limping"?

limp...too much power for stock trans

Turn defuel all shifts on if your tranny is stock
That way the juice will back down the power until the trans has fully engaged the next gear. It really saves wear and tear on clutches.

Next, let your transmission get used to each level... don't go from level 1 to level 5 and expect the trans to be 'ready' for power it has not seen before.
It takes about 10 runst thru the gears for allison to learn how to adjust to the newfound power level
