Complete SM465 Transmission Package

Easily one of the very best four-speed transmissions ever built; the SM465.


sm465_transfer_case_adapter_overheadOur Muncie 465 is professionally and meticulously rebuilt. We use the best components, including bearings, synchronizers, bushings, seals and gaskets built by our SM465 specialist and expert. Any available updates and improvements are performed.

A new, unbent transmission shifter cane is included and ready for the installer to bend to the particular application and driver's preference (if you wish you use your factory stick, let us know and we'll apply a discount).

Applications & Compatibility

Factory Style Build vs. Adapted Build

Our factory style builds are OEM style replacement transmissions that may require the use of the vehicle owner's original tailhousing (either 2wd or 4wd) to complete the installation.

Adapted builds are designed primarily for installation into Jeep vehicles and include the installed aftermarket Novak mainshaft, adapter kit, rear mount, and pilot bushing as indicated for the customer's scenario.

Transfer Case Adaptability

your 465 can be ordered ready to join to the following Jeep transfer cases:

We can also do a full rebuild of your Jeep transfer case if you would like to ship it to us. We can provide any upgrade components for it that you wish. It will be pre-installed to the transmission and ready to lift into your Jeep.

Bellhousing Compatibility

We will configure your front input section for a variety of OEM or conversion bellhousings including:

  • GM 4-11/16" bore bellhousings (machining of your bellhousing may be required - please inquire)
  • GM 5-1/8" bore bellhousings
  • AMC I6 (258 & 4.0L) & V8 bellhousings

We can often source a bellhousing or use your particular GM or AMC bellhousing as required. Conversions to AMC bellhousings will include necessary machining for Crank Position Sensors (CPS), face pockets (if necessary) and the bellhousing rear face bolt pattern. The pilot bushing is included as specified.
