Thanks, Tom. I had heard of them from another site too. Seem well respected. Talked to Rick there and you are correct - backlog is 4 mo's plus. But they will build whatever you want. Will probably use them if we need replacement.A&A Transmissions out of Indy.
They offer a variety of different stages and configurations (Street, Race, Full Manual, etc.)

They're homepage is outdated, they're very busy. They are top tier but have a backlog.
Just call them and tell them what you need.
Hope this helps.
Tom
