Description: *SPECIAL NOTICE* Vehicle Identification Numbers (VIN) and Date Stamping services now available which includes a factory restored finish, Inquire within. * See Stamping disclaimer at bottom of page. Wide Ratio Available, contact me if you prefer wide ratio gearing. For sale is a Factory Replica of the Close Ratio Muncie Rock Crusher Four Speed Transmission typically used in High Performance 1965 to 1981 Corvette, Camaro, Chevelle, Nova, El Camino, Impala, Oldsmobile and Pontiac Vehicles. 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. 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 (or 3885010 Case, if I do not hear from you I will be using the 3851325 Case) with no Vin or Date Code. 3846429 27 Spline Mainshaft Extension Assembly with Drivers Side Speedo, #3831707 Shift Cover Assembly, Aftermarket Bearing Retainer. 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 Transmissions.
