TRNW-2: 8HP75 are these rebuildable

Fri Jan 10 05:40:09 PST 2025

You mean that lug that keeps the snap ring from spinning? I wouldnt recommend grinding/modifying those things. This whole gear train/drum assembly sees high rpm spin-up and -downs during shifts. It might cause a snapring coming off. With the way it is designed it cant come off and only removeable with the tooling.

We keep the cores,but is seems anymore looking for parts in cores is a waste of time. So much stuff is traps and dead ends because this doesn't interchange with that!
