This page is to acquaint people with the identification of popular North American transmissions based on pan shape, case outline, and OEM numbering and coding. This page also offers overall dimension, gear ratios, and number of gears available in each transmission, and originating year, make, and model. | This page is to acquaint people with the identification of popular North American transmissions based on pan shape, case outline, and OEM numbering and coding.

| + | NOTE: "M-10" is not an official designation. This is what most AMC/Rambler people call the M-8 that has a Throttle Valve (TV)/kick-down cable instead of a vacuum modulator and electric kick-down. The M-35 also uses a TV cable. Transmissions with a TV cable MUST have the cable adjusted properly and freely moving to work correctly. Not having a TV cable connected, moving freely, and not adjusted can severely damage the transmission. | ||
| + | |||
| + | TV cable should move in and out easily when the end is gripped between thumb and one finger. On an AMC the cable moves in as throttle is pressed, is fully out at idle. Adjustment procedure is to make sure carb fast-idle is OFF, then adjust clevis to a "loose pin fit" (pin easily slides in/out with no pressure on cable or throttle linkage), then adjust clevis two turns longer. You can go +/1 one turn to tune shifting (longer = harder shifts, shorter = softer), but much longer than three turns and you will find the trnas down-shifting too soon, such as when cruising up a hill at higher speeds. | ||
| + | |||
| + | *Early models with 196 (195.6) use the M-8, most 62s will use the M-35. | ||

The Nailhead pattern trans stayed in production after the Nailhead engine as the "Universal" TH400 due to the shallow bell, which allowed room for a thick adapter. It was also used by many other manufacturers such as Rolls Royce and Jaguar with an adapter ring. The AMC engines also used the TH400 with an adapter from 1969 until late 1973 when GM cast an AMC specific case (and discontinued the Universal TH400). The TH400 AMC case was used until the end of 1979 model production. |

BW automatics were in the 2WD Jeep DJ "Postal Jeep". Transmission corresponded to the size engine, same as AMC car usage. |
