Thank you again, sir. I drained my compressor today. Wow, I hadn't realized how much water had accumulated in there.

Are there any quirks to these transmissions that I should keep an eye out for?

I bought the special tools to measure for the correct overdrive shim thickness. Also, I picked up the sonnax shim kit. How critical is replacing the intermediate shaft spacer? I have the tool to measure for that, as well.

I am really happy with the one that's still in the truck. I have no idea how many miles are on it, total, but the fluid has always been bright and it's always shifted well. I can tell that it's tired and needs to be replaced with a fresh build, on top of the leaking seal, though. I've personally put almost 100,000 miles on that transmission. No towing, just daily driving. The shifts have gotten mushy, even with proper band adjustments, and there's substantial power loss, and I think occasional slipping in third, but it's hard to tell.
