I recently went 'round and 'round with a local trans shop that rebuilt my transmission (ZF 6HP-19) and they finally had to put in a brand new (2012) ZF valve body and eat the cost.

There are a lot of sub-par rebuilts and just plain junk used ones out there so caveat emptor.

no way in hell would i get a new valve body i would either get a sonnex performed on it or Go manual swap. 3k FML.
