the ol' 833 looked good inside, so, a cleaning out of the case, new seals and gaskets, and back together she went. oh, new mount, and reverse switch, it was leaking like a stuck pig. i found out this, like the rear end, was NOT from an AAR like i was told. (imagine that! well, now it matches the non TA block. turns out, the only AAR running gear parts are the top end of the motor......) this tranny appears to be a 1970 vintage, with a 2.66 first, according to my homework from the brewer's website........
