Had Transmission rebuilt for $3000, but still have the problem. After initial build, still had same issue and took it back 2 times to transmission shop, can't figure out what is causing it.

After having the tranny rebuilt it shifted pretty smooth, but occasionally it would shift roughly. It is starting to shift a bit hard into OD again but ONLY on rare occasions! Don't have a clue. The hard shift and the stalling seem to have some correlation but cannot put my finger on the problem. I am taking it back in to the tranny shop and see what they say.
