Luckily I have a spare th400 that’s pretty much junk. So it’s become my first victim of destruction.
I can’t cut a straight line to save my life, so after marking the first cut, drilled some holes along the path to keep it somewhat straight.
Lessons learned so far, When I do the “real” trans it will require more drill sights and aluminum metal shavings get everywhere. ATI suggests doing the cut on an empty case.. I’ll be doing it on a full case so sealing entry points will be critical.
Finished the raw cut and was waiting on the bell housing to arrive before grinding down the trans… low and behold the bell housing turned up.
