The external differences between the three Muncie 4 speed transmissions can be deceiving. If the cover is removed, the pitch of the gears can be seen. In order to tell the difference between an M21 and M22 definitively, look at the helix angle on the gearset. M20 and M21 have a steeper pitch, where the M22 will have a less aggressive pitch. M22s are NOT straight-cut or 'spur gears'. | The external differences between the three Muncie 4 speed transmissions can be deceiving. If the cover is removed, the pitch of the gears can be seen.

It was stout and reliable, but its limited use and short production run didn't support wide aftermarket solutions. In fact GM didn't even stock service parts for the transmissions, instead opting to provide remanufactured units instead of repairing them. Although it ended up costing GM less in the long run, it was a concept not warmly received by the public. Early models were rated for 400 ft-lbs, and later models were rated to 450 ft-lbs. |

− | Starting with the 1992 | + | Starting with the 1992/1993 GM F-body (Camaro, Firebird, Trans Am) the six speed was a Borg Warner-designed, Tremec-built T56 transmission. Although the basic design, case, and internal operation were the same, three different ratio gear sets were available in GM applications. In 1993, F-body cars were equipped with two optional rear axle ratios: 2.73 and 3.23. Beginning in 1994, all T56 cars used the same ratio gear set regardless of rear axle ratio. 1992-1993 T56s with the lower gear sets had a slightly lower torque capacity in the 350 lb-ft range while 1994-later (high) gear sets reduced the side loads on the case and were rated to 450 lb-ft. T56 use continued like this until 1997 when it also started being used in the Y-body (Corvette) as a rear-mounted transaxle, and continued on in F-bodies behind the LS1 until the end of their production. |
− | Of note is the fact that all T56 transmissions share an interchangeable main case; even those found in Holdens, Fords, Vipers, and Aston Martins.

This is because the 1955-'57 Chevys had a perimeter frame and leaf rear springs. These had a 3 point engine/trans mounting system that required a single front engine mount and 2 bellhousing mounts. The 1957 trans is unique in that it also has a long extension housing (tail shaft housing) and a drain plug that the later trans do not. This makes it fairly easy to identify. |

They all have a variable pitch (angle of incidence) stator in the center of the torque converter that changes the torque multiplication when the angle is changed. This feature gave the trans the feel of having a 'passing gear' when the throttle was fully depressed- causing he engine RPM to rise by 500-800. This feature could be found in some of the later GM transmissions and was discontinued at the end of the 1970s. | They all have a variable pitch (angle of incidence) stator in the center of the torque converter that changes the torque multiplication when the angle is changed.
