Built Manual Trans

'10 6.4L with manual transmission and in need of upgrades. I've sheared input shafts with dual disc button and sintered iron clutches, now something else is about to go (different unit). Anyone had theirs built up? Who is good and where? I know Suncoast does good work with Autos but who does good work on manuals?

I tried having a shop in Ohio build mine and am not 100% happy with it. Talked with Scott from Midwest Trans. Without a doubt that's the way to go. Nobody makes billet shafts or anything like that as far as I've found. The guy I had mine rebuilt by was still sending the hard parts to Midwest to cryotreat the shafts and stuff.

Oh yeah I forgot about them. I talked to them years ago about a short throw shifter. Thanks man I'll hollar at them.

I'm curious how much difference the cryo treating makes.
I REALLY wish some billet parts where available

Midwest says they can Cryo treat shafts & gears and that makes them 30% stronger
