Default 66 Posi Problem

I just bought a 1966 with a posi; however, I only have one tire hooking up. Lets start with the idea that I know nothing about positraction except what I have been reading here. I guess maybe its the clutches, but I don't know. Any help would be greatly appreciated. Thanks!!!! B

If it is truly a positraction, then the clutches are most likely shot, and the unit will have to come out.

Its a big block posi. After my research, I was guessing it was most likely the clutches. Now I just have to find someone in south Alabama who can fix it. This is not my kind of project. Thanks!!

Contact Gary Ramadei. He is the best C2 rear rebuilder you'll find.

I have been reading about Gary, and reading his rebuild articles. Thats probably the way to go. I just wonder how long I will have the car out of service. Guess I need to shoot him an email. Thanks

Yeah, it depends on how busy he is but with him you know it will be done right. Shoot him a message, he is very prompt in getting back to you.

BUT, if Gary can't get to it for a few weeks/months I would call Bair's in Pennsylvania. Besides Gary, they are the only one I would recommend. Their turnaround time should be short.

Have you checked the codes on the rear?

It's possible you may have a perfectly functioning, non-posi unit.

5 miles total. The trans fluid will have taken any glaze off the
plates by then.
3) Drain and refill with the correct GM lube and posi additive. I bet in
most cases your problem will be over.
