After finding bearing parts in the pan and most shops hesitant to rebuild 200-4R due to lack of cores and experience we've decided to find a remanufactured one. I see a few, not many, on line and was wondering who is best. I've seen a few from PATC, Monster, and Transdepot. This is for a bone stock 1990 Olds Custom Cruiser in excellent condition otherwise. Any direction would be greatly appreciated. Thanks, Steve.

Wow. They built bazillions of them but since last RWD were, what, 1990, I guess they have gotten a bit scarce.

That 307 wagon won't really need it, but look around for what turbo Buick guys do to them. Those are how HydraMatic should have built the 2004R in the first place.

Has anyone gotten a rebuild from Extreme Automatics?

Lonnie is a good guy, he knows his stuff. He does stay pretty busy

Has anyone used California Performance Transmission? Art Carr's current shop.

I have a 4l60e from Lonnie. 3 years in and going strong. He is a busy guy, though, so expect a long wait.

We went with California Performance Transmission, they had a more street version instead of a modified performance version. Thanks for the help.
