Overdrive expert

I am interested in finding an expert on T-85 overdrive transmissions in the southeast. I have been messing with one for about 3 years and I have it all back together but something just doesn't seem right to me. The main box is fine but it just seems like something isn't quite right with the overdrive unit. It may be fine. I just do not have enough experience with overdrives to know. I would like to bring it to someone who really knows these units & have them take the rear housing off & check it out before I go to all the trouble of putting in the car and then finding out something is wrong. Any ideas will be appreciated.

 

have you installed it in the car and driven it yet? :???:

No I don't want to do that until I have it checked out.
