Revuilt transmission question
Therefore, unless the converter is defective and the lockup clutch is dragging, this is not your problem. A bad trans rebuild could also try to engage the lockup, but that is also unlikely.
Most likely the trans shop messed up an engine sensor or related wiring.
You should scan for codes; auto stores provide a free scanner loan, although you have to pay a high deposit for it.
Take it back to the trans shop; this is most likely their problem/mistake.
