GM Genuine Parts Transfer Case

About this product

GM Genuine Parts Transfer Case Assemblies are designed, engineered, and tested to rigorous standards, and are backed by General Motors. As an important part of the drivetrain for four-wheel drive systems, transfer cases are responsible for engaging and disengaging four-wheel drive. This two speed, part time, manual shift transfer case is for a four-wheel drive system, and has been updated with the latest GM engineering enhancements. It comes with Vespal pad inserts and an aluminum vent instead of plastic. It also features no hassle core return and is available in light duty, heavy duty, and super heavy duty applications.GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Remember that driving conditions and how much the four-wheel drive is used can affect the rate of wear on transfer case fluid and components

Transfer cases experience wear over time
Transfer case fluid breaks down, becoming less effective as it thins and wears out
Debris can contaminate the fluid, accelerating wear if left too long
Transfer case components may become worn or damaged through regular use or exposure to extreme conditions and circumstances
Properly servicing your transfer case and related components can help prevent premature wear or damage
Follow the manufacturer's recommendations for maintenance and transfer case fluid change intervals
Check fluid levels and replace broken down or contaminated fluid in response to recommended intervals or signs of wear
Check transfer case mounting hardware and brackets, drivetrain driveshafts, U-joints, and carrier bearings if applicable, as wear could damage the transfer case
Keep an eye out for signs of wear or failure, and check the transfer case for leaks or damage as needed
Regularly inspect transfer case assemblies for signs of damage or wear and replace them if signs of damage are found

Replace or service transfer cases and transfer case components when you experience signs of wear, such as:

Leakage at transfer case gaskets or seals and low transfer case fluid levels
Abnormal vibration or noises, such as grinding, whining, popping, and clunking
Jumps in and out of four-wheel drive
Difficulty engaging four-wheel drive
No transmission of power to one or both sets of wheels

Frequently Asked Questions

Yes, always consult the Vehicle Owner's manual or an expert technician before making any repairs or adjustments.

Yes, consult the product's fitment information to see if it will fit the year, make, and model of your vehicle.

No, transfer cases are used in vehicles with four-wheel or all-wheel drive systems.

Yes, four-wheel drive transfer cases give the option of two-wheel drive or four-wheel drive, and engage when activated electronically or manually by the driver. When engaged, power is split evenly between front and rear wheels, and when not engaged, the vehicle is in two-wheel drive. All-wheel drive systems are always on, getting information from the wheels, and sending power to the wheels with the most traction at the time of slippage. This happens automatically and requires the driver to do nothing to engage it.

Yes, part time transfer cases have a main mode of two-wheel drive, usually with the rear wheels powered. When needed, four-wheel drive can be engaged, and the front wheels are powered. Front wheel binding can occur on dry pavement when in four-wheel drive. Full time transfer cases have constant four-wheel drive, with all four wheels powered all the time. Differential (planetary gears) are incorporated into the transfer case so binding does not occur on dry pavement.

Yes, gear-driven transfer cases use a set of gears that mesh in order to drive the front or front and rear driveshafts. They are strong, heavy units used in large trucks, and require a vehicle to be stopped or moving very slowly to shift into four-wheel drive. Chain-driven transfer cases use chain to drive one or two axles, and are quieter and lighter than gear-driven transfer cases. They are used in many newer trucks and SUVs and can be used for on-the-fly four-wheel drive shifting at higher speeds.

Yes, electric shift operates by activating a motor on the transfer case, which rotates a linkage to engage the main shaft. The main shaft transfers power to the front driveshaft for four-wheel drive. Manual shift operates by moving a lever attached to a linkage on the transfer case, which manually engages the main shaft. The main shaft transfers power to the front driveshaft for four-wheel drive.
