| Note: Model designations started with a letter prefix that indicated the shifter positions. The forward or remote shifter models, with only a few exceptions, were fitted to bench-seat-equipped trucks, and the shift mechanisms were moved 3-4 inches forward to clear the bench seat. The direct-shift units were seen on bucket-seat models. A remote-shift trasmission also had a remote-shift transfer case with extended shift rods, so you can only match up direct-shift transmissions with direct-shift transfer cases. |
| G and R= Forward or remote shift; W and L=Direct shift. |
| 1 | A very weak four-speed with an aluminum bellhousing, a cast-iron case, and an aluminum extension housing. It was 20.75 inches long and had a 72mm input bearing. |
| 2 | Another weak four-speed and the last four-speed commonly available in 4x4s. It has an integral cast-iron bellhousing and case. It was also 20.75 inches ling but had a 75mm input bearing. |
| 3 | A weak five-speed that was 20.75 inches long and had an integral cast-iron bellhousing and trans case. It had a 75mm input bearing. |
| 4 | A better five-speed with an integral cast-iron bellhousing and a case but a bigger 80mm input bearing. It was also 20.75 inches long and the last of the short trannies |
| 5 | The first of the long trannies, it was 25.5 inches long and had a separate aluminum bellhousing, case, and extension housing with a cast-iron bearing support plate sandwiched between the case and the extension. It used an 80mm input bearing. |
| 6 | An orphan unit in the long category, similar to the G52 but with a slightly wider input bearing. |
| 7 | Like the G52 but with direct shifting and an aluminum bearing-support plate. |
| 8 | Though not used in the solid-axle era, this is the best tranny for swapping purposes. Not only does it have the lowest First gear, it was built stronger to withstand the turbo engine. It has a 23-spline output shaft and a 92mm input bearing. It bolts up to any geardrive transfer caseif a 23-spline input gear is installed. A 9.25-inch clutch and companion flywheel were used with turbo engines (versus the 8.88-inch). It can also be retrofitted to nonturbo engines. |
| 9 | The token automatic. A four-speed auto, it was a decent but uninspiring piece that soaked up enough of the four-cylinder's power to give new meaning to the term slow. It was also fitted with a lockup torque converter. |
