No 1st 2nd or 3rd but R works

Build you a 904. A chimp could be trained to do it.

Anybody that would pay 3K for a 904 rebuild, "lifetime warranty" or not is a moron, borderline downs syndrome. Sorry, somebody had to say it.

How many loopholes do you think companies like that have to get out of warranties?

Do yourself a favor. Get the 904 and 727 ATSG service book off Ebay. Bout 25 or so bucks. That's about the best manual you can get. Then decide if you want a shift kit or not, what kind and follow the instructions closely. I have a friend who runs a shop for a living. He can literally rebuild a 904 on the bench in about 45 minutes flat. That's runnin the guts through the cleaner and all. If it was clean already he could do it in 20.

By doing it yourself, you actually do something valuable for yourself. You learn. No warranty on earth is worth as much.
