My transmission is 722.004 02 115004. I was listing what I see as the main differences between the three speed 722.0 and the four speed 722.1. I know from looking in EPC that there were many minor (but important) parts changes throughout the production run. Actually, everywhere I've checked, the overhaul kit is the same for 722.0, 722.1, and 722.2 transmissions.
