Pettibone PM245 What is Broken? Transmission Disassembly Allison TT2220-1

[@Otis728]

I have a tt2221-1 transmission in my loader running 15w40 motor oil. It needs to rev high to move. Do you prefer the Dexron?

I know it’s too late, but that rubber sealing ring on the suction tube is a flex master pipe gasket. I believe Eaton makes them.

I knew somebody knew what that was and where to get it. Thank you I will order one in case it ever has to come apart again!
