For sale is a Close Ratio Transmission for 63 thru 74 GM products including Grand Sport Corvette, Chevrolet, Oldsmobile, Buick and Pontiac and is a rare opportunity to own a virtually brand new M-22 Close Ratio Rock Crusher Transmission with a completely new gearset. This transmission is a direct replacement for a Borg Warner T10, Saginaw, M-20 or M-21 with no other changes necessary to swap into your vehicle. If you are replacing a 27 spline Muncie M-20 or 21 your existing shifter will swap over. This is about as close to a factory supplied transmission as you can get. #3851325 1" Case Assembly, #3857584 27 Spline Mainshaft Extension Assembly with passenger side speedo, #3831707 Shift Cover Assembly and Aftermarket Bearing Retainer.

Be very wary of some of the sellers on E-Bay listing transmissions with new gears but photographs depicting used gears, the use of silicone instead of gaskets, high quality gaskets and High Tack Gasket Sealant only. 

DO NOT purchase a transmission without French Locks on the front bearing retainer, there is a good chance the bearing retainer will loosen from throw out bearing vibration, only GM type French Locks on my Transmissions! 

Some are even depicting Saginaw`s as M22`s! 

DO NOT  purchase an M22 without a drain plug, you will have no way to effectively remove all of the gear lube including metallic particles that will continue to circulate and eventually lead to premature failure.

All my transmission cases have the Countershaft bores re-bored using a parallel boring process where the counterbore and the mainshaft are truly parallel. This process also produces a virgin counterpin opening thereby assuring a tight, leak free press fit.  

All my photographs are of the actual transmission you will receive. Be very wary of sellers using file photos or multiple product sales, you may be disappointed when the transmission you thought you purchased is not the one on your doorstep.

Buy with confidence from a seller that works very hard to maintain feedback satisfaction. Be sure to read my Feedback comments prior to purchasing any Transmissions.

Mystery Muncie First Gear noise eliminated.

And by the way all my M22`s come standard with the Rock Crusher Blower Like Whine!
