Pet! just noticed you were a recent addition to the cast and crew of the funny pages. Welcome to the forum!
I really have been meaning to do this for yrs. Take a whole stage 3 to a auto transmission place, find the oldest, ready to retire guy and show him the guts. 1st thing wrong with em is they are straight gears. So the thing sounds like a 1957 Chevy going 27 MPH in reverse.
I am thinking there are hex gears that could be swapped out that are already mass produced.
Better bearings! They need better bearings and in places, any! snork.
Last but really important, a manual or wet clutch. lol @ the "engager"
Take all this with a grain of salt. I never pursued it so who knows what I don't know. But I really do think it could beat out all the *trannys out there.
The reason for asking for help from a well experienced tech, transmission person and not an engineer is that they see the long term wear and results from the enevitable comprimises that come with designing some thing like this. Kinda like reading the end of the book first and knowing the outcome of mistakes made in the early stages.
*I keep getting really, really funny & sarcastic PMs from a transgendered member here. She is a riot and writes every time I go off on a tangent about "trannys"
Truly funny stuff and she won't let me post em.
