Response to O/T, catastrophic trans failure redux.
Went back and took closer look at your parts. Is the 1st gear blued in the front that would ride against the slider block? If so not enough clearance but it also a possibility that the aftermarket mainshaft could be at fault as to not enough clearance between it and the gear as Mike explained. The main shafts with only a single groove around it such as yours need to be ground on to enhance the oil to be spread across the inner face of the gear.
