M22 transmissions

[Hotrodpaul]

One of the problems with the standard muncie gear angle is that it places a large thrust load on the front input bearing and retainer, causing cracked cases and thread stripping around the bolt holes when launching at high RPM on slicks. The torque also tries to seperate the gears based on helix and tooth pressure angle causing the countershaft to flex. Some of the transmissions designed for racing have a center support near the middle of the countershaft and mainshaft to control the deflection. Straight cut gears with a 14 1/2 degree pressure angle would work well, and would not create power robbing thrust friction forces. I think the Jerico boxes used in NASCAR are similar with dog style synchro engagement. These would make a nice transmission for really fast shifts if the rules permitted.

I just had a brand new M22 built by 5speeds.com . Paul Cangialosi is the owner and he worked with Autogear to develop the new Muncie "Super" parts. Very knowledgable and manual transmissions are his passion. I checked out several sources for these Super Muncies before selecting him to do mine. As far as 'case stretching', these are built with an iron mid-plate and when combined with those beautiful, beefy Supercases, they make for a very strong assembly.

The tremec i have now has the dog style syncro and shifts awesome.Thanks for your help guys.

The helical angle of the Doug Nash Muncie gears are the same as an OEM M-22...
I have several sets in stock if your interested... Crash
