I'm attempting a rebuild on my '90 4T60. Anyone successfully done this one before? Any good write ups anywhere?

Sorry, no writeups or how-to'* for that trans. But if you goto www.atsg.us they have the books you need. That'* where I got mine from.

I will. I saw those books on eBay today actually so now i know they are legit. Thanks! I actually found what looks like a pretty good video on that trans on YouTube today too. And guess what books he had?...i am gonna watch them some time soon. I will post links to them as well.

Here'* the video i found. In the description are the links to parts two and three as well. It'* pretty good. I've only watched part 1 so far. I'm feeling more confident.
