The Novak Guide to the
GM Muncie SM465 Transmission

For a video version of this article, click here
The SM465 is an outstanding, heavy-duty truck transmission designed and used in ½, 3/4 and 1+ ton trucks. The SM465 was made by General Motors from 1968 to 1991. They are found primarily in GM and Chevrolet trucks, Blazers, Suburbans and many other models falling under the 1/4-ton to 1-1/2-ton platforms.
The 465 is an intellegently designed and very well-built transmission and remains easy to locate and generally inexpensive to buy and maintain. The strength, relatively short size and the gearing of the transmission make it a good choice for a variety of on-road and off-road situations. It has a very good set of road manners contrasted by its enormous off-road brawn.
The "SM" in the transmission's designation stands for Syncrho-Mesh, in the tradition of other GM gearboxes. It is also referred to as the CH-465 or CH465 by factory literature.
Identification
The SM465 is a top loaded, top shifting truck style transmission. This transmission is 12 " long and features a cast iron top cover that is retained by eight bolts. The SM465 case is of *cast iron. The case itself is generously ribbed both vertically and horizontally.
The SM465 has a 1-1/8" diameter, ten spline input shaft that has a stick-out of 6-1/2" from the front face of the transmission. The pilot tip is ~19/32" in diameter. The front bearing retainer flange measures an unusually large 5-1/8" in diameter and the bearing retainer tube is 1-3/8" in diameter. The front bolt pattern is the consistent GM Muncie / Saginaw four-bolt pattern as found on GM bellhousings and transmissions from the 1940's through the 1990's.
Features
The 465 enjoys a very low compound gear at 6.55:1 and as such it is a popular choice for those wanting a very low crawling gear.
The SM465 features power-take-off (PTO) ports on the passenger and driver sides of the case.
The shifting pattern for the 465 is in the standard "H" pattern with reverse gear being to the right side, and down.
SM465 Versions
There are three principal versions of the SM465, each based on the era and configuration of the transmission. There is no known mechanical superiorities to either earlier or later versions.
Earlier SM465
The earlier era of the SM465 include the 1968 - 1978 transmissions. There were both 2wd and 4wd versions. Internally, they are identical to each with the exception of the transmission mainshaft. The 4wd version of this mainshaft (or "output shaft") has a 10-spline output with a 2-5/8" stickout and an accompanying 4wd adapter housing. The 2wd version has a 35-spline threaded mainshaft compatible with a driveshaft yoke, and accompanying 2wd style tailhousing.

Parts for the
SM465 Transmission

The SM465 is arguably one of the greatest four-speed transmissions ever built, and reconditioning one is a worthwhile project.
The Kit
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features all the consumable and wear item components.
Our kit standardizes the SM465 thrust washer and endplay and we recommend that you use the supplied shaft bushings with the supplied thrust washer for simplicity.
There are two versions of our rebuild kit, each compatible with all 2wd, 4wd and conversion 465's:

• The first and most common kit is for 1968-1987 versions as well as 1988-1991 versions with the narrower .68" front bearing.
• The second kit is for the 1988-1991 version - typically with the aluminum top cover - with the wider .83" front bearing. The only way to know this version is to remove the front bearing retainer and check for a #211 bearing or to remove it and measure its width.

Rebuild Requirements
It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.
We suggest the rebuilder have access to a set of snap ring pliers, a bearing puller and a hydraulic press.
