Time for 727 rebuild.

Wow. Good thing you took it apart.
No expert. I did it once. Not terrible. Took my time. Used the shop manual, the other Torqueflite book and some forum posts here and moparts for pics. For parts I went with A&A and just worked with them. I think you could do the same with a couple of the other well reputed guys too. It gave me a level of comfort working with Rick that I was getting the most appropriate stuff for what I was doing. Mine was a little more than a rebuild, but nothing radical. Already had DC/MP shift kit (which was really a Turbo0action shift kit).
