The GM SM465 is said to be one of the greatest four-speeds ever built.
The Borg-Warner T18 & T19 transmissions are famous in the truck and off-road world, and this reputation is well earned.
The New Process 435 is a supremely good four-speed with an excellent history
The SM420 is the great predecessor of the four-speeds and remains a great choice for several Jeep applications.
The T98 transmission is the predecessor to the T18 and similar in appearance and design
The T176 (and T177 / T178) is native to 1980 - 1986 Jeeps as the medium duty upgrade
The SR4 is a car transmission that was installed in CJ Jeeps for two years
The T4 was the standard four-speed in the 1982-1986 CJ
The AX15 is a surprisingly strong transmission, and was a serious improvement over many of its lighter-duty predecessors
The NV3550 was New Venture's answer to the AX15, and in the same strength, operational and size category
The NV4500 is a heavier-duty five-speed as found in full size GM and Dodge trucks
The T5 was the standard five-speed in the 1982-1986 CJ
The AX5 was the light-duty, five-speed transmission in the 1984-2003 XJ, YJ & TJ Jeeps
The Peugeot BA10/5 had a gratefully short run in Jeeps
The T90 is the most famous of the Jeep three-speed transmissions
The T150 was strong, and the last of the Jeep three-speeds
The T15 was the strongest of all the three-speeds
The T14 is the T15's little brother. Not too tough but a pretty good gearbox
The T86 is kind of a T90 knock-off. It was the transmission first offered with the Buick V6 engine
The NSG370 has the Benz air about it. Lots of gears and a unique, but durable design
