For sale is a Factory Replica of the M22 1968-74 CLOSE Ratio Muncie Rock Crusher Four Speed Transmission typically used in High Performance 1970 thru 1974 Corvette`s, Camaros, Chevelles, Nova`s, El Camino`s, Impala`s, Oldsmobile's and Pontiacs. 

Also included are Hand Fitted Synchronizer Sliders and Hubs. Some sellers are mixing used non locking sliders with locking gears. All gears sold today utilize a locking synchronizer method where you MUST use a locking slider. If a factory non locking slider is used the transmission will eventually pop out of gear. The hand fitted locking sliders/hubs improves shifting quality through all RPM ranges.

The Case also includes a 1" Steel Countershaft bushing. 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 ensuring a tight, leak free press fit.  

Most M22`s sold on Ebay do not have a new countershaft bushing and you run the risk of leaking or worse yet rotating countershafts.

This transmission will also fit all 57 thru 74 GM products and is a rare opportunity to own a virtually brand new infamous M-22 CLOSE Ratio Rock Crusher Transmission. 

Many transmissions on Ebay are sold with a combination of new and used parts. If the seller does not list ALL the new parts you must assume the non listed parts are used.

Do NOT purchase a transmission with 50 year old factory shift arms, the aluminum side cover bores are worn and the shift arms wobble around in the bores of the side cover. Loose and wobbly shift arms may leak and possibly lock in gear.  

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! 

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. 

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 Transmission.

Mystery Muncie First Gear noise eliminated.

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