Muncie Close Ratio - M-22 Rock Crusher Four Speed Transmission - ALL NEW GEARS

**Lately there has been an increase in the number of people selling M22 transmissions. Most start with a worn out M 20-21 disassemble, decide what used parts are acceptable and re-use many worn out parts. They start the advertisement by stating ALL NEW GEARS.  If the seller does not list ALL the new parts, you must assume the non-listed parts are used.  This strategy is to take your mind off the fact that the balance of the parts may be from the worn out transmission they started with. If you are tired of buying transmissions with used parts represented as rebuilt perhaps it is time to purchase a transmission with ALL NEW interior parts including new Auto Gear Shift Arms that replace the worn out and wobbly 50+ year old shift arms that may leak and possibly lock in gear.  I am so confident of the product I produce that I will include a copy of the receipt for all the NEW interior parts. Simply request a copy and I will include in the shipping crate. 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. 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!** - **This transmission is completely restored including the following:** - **Case Media Blasted and finished with VHT (2000 degree) high temperature coating.** - **All New Grade 5 Hardware.** - **New Auto Gear 32 Spline Tailhousing.** - **New Auto Gear Aircraft Aluminum Mid Plate.** - **New Auto Gear bolt in Countershaft.** - **New 32 Spline Mainshaft.** - **New Auto Gear Forward and Reverse Shift Arms that accept all year levers.
