Well, looks like she's had it. Was coming back today from a quick run with it and she started hesitating going in and out of gear and slipping. There is a buzzing noise in forward/reverse gears coming from the bellhousing area - maybe the converted crapped out. It threw a P07ll trans temp code (but the TCC solenoid that sends that signal was just replaced). Need to decide whether I want to rebuild it (have only rebuild 3 speed torqueflites before and not the OD units) or whether to use an extra unit I picked up recently that was rebuilt and working fine according to the guy that pulled it ( I could tell it's been rebuilt).

Thoughts??
