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

SM465 Transmission Rebuild 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 for both the main case and top cover shift rails.

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. Next are the 1988-1991 versions with the narrower .68" front bearing.
  • The last 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.

  • Kit 465MR-1, master rebuild, SM465 transmissions, 1968-1987 versions

  • Kit 465MR-2, master rebuild, SM465 transmission, 1988-1991 with wide front bearing

Rebuild Requirements

It is 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.

Billet PTO Cover

Kit PTO-K, PTO cover, six bolt style, billet

This is the rigid PTO cover that every Novak-built transmission gets, and we recommend them to our customers. They seal better and stay that way for far longer than the stamped steel versions from the factory. Stainless button-head fasteners are included.

Shifter Retention Kit, SM420, SM465, T176, NP435

Kit, shifter retention, SM420, SM465, NP435, T176 transmissions, #SLR-176K

This shifter retention kit and mini-boot will lock in your shifter stick and give it a better barrier than factory from dust and water ingress.

Shifter stick for the SM420 transmission

Stick, shifter cane, SM420 & SM465 transmissions, upgraded finger, 18" tall version, #WT304-28-18

Worn out shifter sticks or factory shifter sticks that are wierdly bent for Jeeps or a stick that's missing altogether... Replace it with the new, straight version that is a more appropriate length for a Jeep and ready to take an industry standard knob.

Shifter stick for the SM420 & SM465 transmission

Stick, shifter cane, SM420 & SM465 transmissions, upgraded one-piece version, 24 inch, #WT304-28-24

Worn out shifter sticks or factory shifter sticks that are wierdly bent for Jeeps or a stick that's missing altogether... Replace it with the new, straight version that is a more appropriate length for a Jeep and ready to take an industry standard knob.

SM465 Gaskets Kit

Gaskets set, SM465 transmission, #WT304-55

This is the gasket kit to seal up your SM465. This is included with our master rebuild kit, adjacent.

SM465 mainshaft journal bushing kit

Kit B465, bushings, SM465 mainshaft journals, 1st, 2nd & 3rd gear, #B465

If purchasing the mainshaft version of the Novak adapter kit, these bushings are required. Note that these also come in our master rebuild kit (adjacent). If purchased at the same time as the adapter kit, we will press one of the bushings on the mainshaft for you - the other two must be installed with your gears due to sequencing.

Kit, update, 3rd gear and slider, SM465 transmission. TorqueLock / Anti-jump-out design, #WT304-11AX

The SM465 is pretty close to perfect in its design, but this update to 3rd gear and its slider are considered to be essential. The tapered clutch design prevents 3rd gear from kicking out under torque. This and other components can be seen here.

SM465 Countershaft Billet Front Cover

Kit, cover, front, countershaft, SM465 transmission, #465CSC

This billet aluminum front bearing cap for your SM465 countershaft is far more rigid than the stamped steel, leakage-prone factory unit. It comes with countersunk fasteners.
