Many engine options have been offered for the CJ-5 over it's long production run. The original engine offered in the CJ-5 was the "Hurricane" F-Head 134 I4. The first optional engine offerred for the CJ-5 was the Perkins 192 I4 diesel followed by the "Dauntless" Buick 225 V6. When AMC purchased Jeep from Kaiser, they soon made the AMC 232, 258, and 304 available in the CJ-5. The last three years of production, the GM 151 I4 was the standard engine.


The T-90 3 speed was the standard transmission for the CJ-5 for many years. It's close brother, the T-86 3 speed was used with CJ-5s with the Dauntless V6. The T-14 replaced the T-90 and later the beefy T-15 was used with CJ-5 with the 304. The T-98 was an optional 4 speed for the CJ-5 until 1971 when the T-18 became the optional 4 speed. In 1976, the T-150 became the 3 speed for the CJ-5. In 1980, the heavy duty 3 speeds and 4 speeds were no longer offered. The lighter duty SR-4, T-4, T-176, and T-5 were used.
