I can't believe all the run-around the dealer is giving you.
If they are so confident that the transmission is properly repaired they shouldn't hesistate to honour their repair in some form or another.
I really don't understand why they didn't put in a new tranny right off the bat.
Of course, I'm just restating everything that's been said on this thread. Hoping to give my good friend some "in thought" support...
