The Muncie SM420 is a heavy duty, four-speed manual transmission that was produced from 1947 to 1967 by General Motors for civilian use in a variety of pickup trucks, buses, dump trucks and heavy equipment. They were used in some military vehicles into the 1980s. It was replaced in civilian vehicles by the Muncie SM465 transmission in 1968.
A few months after the model introduction, Oldsmobile added a "power pack option", which included a four-barrel carbureted, high-compression (10.25:1), dual exhaust version of the 215 cu in aluminum V8, and a shorter 3.36:1 final drive ratio with either manual and automatic transmissions. [5]
The designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2. ...
This transmission used a 3.50/2.05 1st/2nd, 1.38 3rd, 1.03:1 4th, .80:1 5th, and 3.94:1 final drive. [citation needed] The Getrag 282 used in Quad 4-equipped 1990 to 1991 Pontiac Grand Prixs and Oldsmobile Cutlass Supremes is rumored to use a 3.77/2.19 1st/2nd gear while retaining the 3.61:1 final drive ratio.

The 1891 Panhard et Levassor is considered a significant advance in automotive transmissions since it used a three-speed manual transmission. [2] [3] This transmission, along with many similar designs that it inspired, was a non-synchronous (also called sliding-mesh) design where gear changes involved sliding the gears along their shafts so ...
The V6 on the 1985 model and part of the 1986 production year came with a four-speed with a final drive ratio of 3.65. The lower-geared 4.10 four-speed transmission showed improved acceleration, but sacrificed fuel economy. Isuzu and Muncie (Getrag) five-speed transmissions were available, depending on model and equipment beginning in 1985 for ...
