The Tremec T176 transmission was the optional four-speed transmission found in 1980 to 1986 Jeep CJ models. It is a good transmission when well maintained and has often been adapted to V8 and V6 power.
Rated at medium-duty, the T176 is stronger than its compact size may suggest. Though it only holds a candle to the truck style four-speeds' strengths and capabilities, the T176 is frequently retained in CJ Jeeps when married to mild GM V6 and V8 power.
The T177 and T178 are the J Series versions of this transmission as supplied with the 258 I6, and they feature significantly longer input shafts and bellhousing spacers to compensate for the deeper bulkheads of the FSJ Jeeps. The gearing differs as well. References to the T176 are largely similar to the other two versions. Failures of the T17x are more common in the Jeep trucks as they had greater weight and duty demands.
For the big-gears crowd, it is popularly replaced with the Ford T18 and Ford NP435 transmissions, since they share a similar bellhousing bolt pattern and compact installations.
Features
The T176 is a top loaded, top shifting transmission. The T176 is fully synchronized in the first through fourth gears. All gears are helically cut.
Identification
The T176 transmission case is 10-1/4" long or 12.9" long with the Jeep style adapter, and features a cast aluminum top cover that is retained by six bolts and a main case of cast aluminum.
The Jeep T176 has a 23 spline output shaft for connecting to the transfer case input shaft. The transmission has a 7-1/2" input shaft (stick-out length) with 1-1/8" x 10 splines and a neoprene front bearing retainer assembly. The pilot tip is ~19/32" in diameter.
The T176 features a conventional "H" shift pattern, with reverse being towards the passenger and down.
Typical casting numbers found on the T176 main case can be C-2604203 or c-2604206. Top cover casting numbers like C-2604208 are common.
