Our Remanufactured CH465 / SM465 Transmission Upgrades & Upgrades

Put simply, a remanufactured transmission is a used transmission that has been returned to a like-new condition. Each remanufactured CH465 / SM465 is built in our state of the art factory by skilled Certified technicians. They test everything from metal thickness to spring tension before the process begins. And every hard part” that doesn’t measure up to the manufacturer’s original specifications, gets replaced. By the time it’s finished, a reman transmission should perform exactly like a new one. Now lets take a closer look at what sets a Street Smart Transmission apart from the rest: 

All Gears & Shafts Meet OEM Specifications 

All of the gears and the main shaft inside each remanufactured CH465 / SM465 that we produce, is carefully inspected for cracks and tested for straightness. Any hard part that shows signs of wear or damage is immediately replaced. 

Upgraded Seals & Gaskets 

To increase longevity, every remanufactured CH465 / SM465 transmission gets upgraded seals and gaskets that are made from a stronger heat resistant material. This upgrade is especially important for severe service (towing, off-roading, performance driving), where heat buildup can be a serious concern. 

Durable Bearings 

All of the new hardened bearings in a remanufactured CH465 / SM465 transmission not only perform better under load. They also create less friction for reduced operating temperatures and a longer transmission life.

Fully Inspected & Dyno Tested 

Every remanufactured Street Smart Transmission undergoes multiple inspections by Certified inspectors throughout the build process. Once complete, your newly remanufactured CH465 / SM465 transmission is dyno tested to break-in all of the new parts, and to ensure that everything works correctly prior to shipment. And speaking of, shipping is always Free, and you also get a 3-Year/Unlimited Mile Nationwide Warranty that covers parts and labor for repairs that are performed by any licensed repair shop in the country.

About the CH465 / SM465 Transmission

Used from 1968 – 1991, the CH465 / SM465 transmission is a heavy duty 4-speed manual gearbox that was used in a number of General Motors 1/2 – 1-ton trucks. Both 4X2 and 4X4 versions were made, and this durable Chevy transmission saw service in everything from the Chevy Suburban to the GMC 3500 Dually. Although the exact history of the nomenclature isn’t known. It’s widely speculated that the CH’ in the CH465 transmission name stands for Chevrolet, while the SM’ in SM465 transmission is thought to stand for either Saginaw Muncie or Synchro Mesh. Either way, this is an incredibly reliable way to change gears. Especially if you buy a remanufactured CH465 / SM465 transmission. 

CH465 / SM465 Transmission Technical Specifications 

The CH465 / SM465 transmission is a top loading 4-speed manual gearbox that was engineered to withstand both high output torque and heavy duty use. An example of this was the transmission case on earlier versions that was made completely of cast-iron and had extra ribbing for added strength. Later versions of the CH465 / SM465 transmission saw aluminum integrated into the top half of the transmission case, and a hydraulic clutch release was added after the 1985. Since the CH465 / SM465 was going to be used in hard working applications, dual PTO ports were added (one on each side) to power auxiliary equipment. And in most applications, only 2nd-4th gears were synchronized. 1st/Granny-Low was constant mesh. 

Length: 12 inches 

Height: 18 inches 

Weight: 175 pounds (full cast-iron case) 

1988 – 1991 versions of the CH 465/SM465 transmission got a direct drive fourth gear switch to signal the ECU of a cruise/lean mode operation.

Remanufactured CH465 / SM465 vs. Rebuilt or Used

Reman CH465 / SM465 vs. Rebuilt CH465 / SM465?
Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value. What kind of warranty coverage are you looking for? Remanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop.
Reman CH465 / SM465 vs. Used CH465 / SM465?
Buying a used CH465 / SM465 transmission may save you money. However, if the unit does not work properly after installed, you will more than likely have to pay the labor again for removal and reinstall of the transmission PLUS the freight to ship the transmission back to the salvage yard. The additional cost may be higher than installing a reman or rebuilt transmission–not to mention the extra downtime. Warranties for a used transmission is only 30 days, 60 days, 90 days or 6 months. Used transmissions, since there is no way to know how many miles are on them, may fail at any time.
