If the transmission came behind a GM manufactured engine, it will work behind the 4.3 you have.

Jeep Cherokees and Comanchees had options of the GM manufactured 2.5 4-cylinder, and the 2.8 V-6 engines.

I would like more information on the year and engine that was in the Jeep.

Jeep has used many different engines & trannys over the years

The 2.5 in the Comanche was an AMC built motor. Nothing at all like the 2.5 Pontiac built motor used in the S-10. The 5-speed trans in my '86, 2.5 Comanche was a piece of junk...........


If, your truck came with the 2.8 V-6, it will have the GM Metric pattern on the bell it won't bolt up to a 4.3.


If your looking at an early model, up to about '89, it's probably an AX-5 built by Aisin in Japan. It will have a 1", 14 spline input shaft and either 21, or 23 splines on the output shaft.

Around '89, they started using a BA 10/5, built by Peugeot in France. It will have a 1 1/8", 10 spline input shaft with the same 21 or 23 spline output shaft.


Even if you where able to adapt one of these transmissions to a 4.3, you still wouldn't have much in the long run. Neither of them where ever considered durable or strong........Dan

The only 4cyl engine that had the same bell bolt up was the Pontiac old iron duke 2.5
It came in......

# Model Year Description
1 AMC 80-82 4-151 Cncrd,(2.5L)
2 EAGLE 81-83 4-151 (2.5L)
3 JEEPCJ 80-82 4-151 (2.5L)
4 JEEPCJ 83 4-151 (2.5L, VIN "B")

But they also came with a sorry a** SR4 4speed or a chrysler 904 automatic.

Sorry to prove us both correct, but GM 2.5's WERE installed in Jeeps.

Vin code "B" 151 inch engines in 80 through 83 Jeeps, and other AMC vehicles, were built by Pontiac.
Vin code "U, H, and P" 150 inch engines from 83 to 97 were built by AMC which was bought out by Chrysler, and eventually became Diamler/Chrysler.
Vin code "W" 173 inch V-6 engines in 1984, 85, and 86 were manufactured by Chevrolet.

If it came with either of these engines made by GM it WILL NOT directly bolt up to the 4.3 Chevy V-6, the bellhousing bolt patterns are different like stated before.

Jeep also used a Buick 350 in 1970 and 1971.
