The transmission wants to drag the engine down when putting it in reverse after it is up to temperature. It will sometimes it will do it in the forward gears if its been driven all day. Everything functions normally otherwise. The tranny came from a rollover and is supposed to have 85k miles

 

Sounds like a cross leak somewere, bad seal or gasket maybe.. sounds like she may need a complete tare town and put in new seals gaskets and check all bushings and clutchs/bands

 

Not sure which one cured it but I changed front pump and converter and it cured it, I'm leaning toward the converter being the culprit.
