Manual Transmission Parts for Jeep CJ5
T18, T150, T176/T177, SR4, T4 & T5 – All Transmission Options at a Glance (1972–1983)
Six Transmission Generations Across Eleven Model Years.
Across the eleven production years of the Jeep CJ5 72-83, no fewer than six different manual transmissions were used – a variety that often confuses customers searching for parts. It started in 1972 with the rugged 4-speed T18, replaced in 1976 by the more affordable but similarly solid T150. Starting in 1980, the stronger T176 and T177 followed, joined by the lighter SR4 for the smaller four-cylinder engines. The final transmission generation arrived in 1982 and 1983 with the T4 (standard) and T5 (with overdrive fifth gear), offered side by side. All six transmissions share similar wear patterns – synchronizer rings, bearings, and oil seals wear down over decades in much the same way – but differ significantly in design and parts. If you're unsure which transmission your CJ5 has, you'll find the matching subcategory below along with its production years.
- Early 4-Speed Transmissions (1972–1979): Parts for the T18 transmission and the T150 transmission – the first two 4-speed gearboxes in the lineup.
- Later 4-Speed Transmissions (1980–1986): Parts for the T176 & T177 transmissions and the lighter SR4 transmission.
- Final Transmission Generation (1982–1983): Parts for the T4 transmission and its overdrive counterpart, the T5 transmission.
Proven American Brand Quality Across Every Transmission.
Shafts, gears, bearings, gasket kits, and housing components across all six transmission variants come predominantly from Crown Automotive – American engineering that has proven itself in the Jeep parts market for decades. Individual parts like housing bells and cluster gears are supplied by Omix, also American-made, reverse gear switches come from Standard Ignition, clutch kits and flywheels from Platinum Driveline, and select gaskets are from Mopar.
