Transmission & Transaxle

The transmission or transaxle in your vehicle transfers the power produced by the engine to the wheels. These components use precise gearing, and in some cases, hydraulic pressure, to shift gears and keep your vehicle driving as it should. There are many moving parts that can wear out or break due to extreme driving conditions, but some damage or wear can even occur from daily driving. When parts of your transmission or transaxle wear out or break, shop O'Reilly Auto Parts to find what you need for a complete repair.

Transmission and Transmission Parts

Transmissions use the rotational power from the engine and transfer it through a series of gears to get this power to the wheels. Depending on the type of transmission, the engine transmits power through either a clutch or torque converter and a flywheel or flexplate. With all of the moving parts of a transmission, a missed shift or normal wear and tear can cause damage that may cause the transmission to wear out and start missing shifts or make it difficult to change gears. If you need to repair, rebuild, or replace the transmission on your vehicle, shop O'Reilly Auto Parts for everything you need to restore your vehicle's performance and driving comfort.

Transfer Cases

Transfer cases are designed to send power to all of the wheels on a four-wheel drive or all-wheel drive vehicle. The transfer case on an all-wheel drive vehicle is constantly engaged, while the transfer case on a four-wheel drive vehicle will need to be engaged, either manually or automatically, to send power to the front or rear axle. Depending on the year, make, and model of your vehicle, the transfer case may be manually engaged with a lever or with a motor that is activated with a button or switch. Transfer cases use gears and chains to transfer motion to the wheels, and require a variety of bearings and seals for smooth operation and proper lubrication. If you need to repair or replace a whining, clunking, or broken transfer case, shop O'Reilly Auto Parts for the parts you need to get your four-wheel drive working again.

Differential Parts

Differentials typically contain the ring and pinion gears and axles that send the power from the transmission to the wheels. Differentials also contain several bearings to support the axles and pinion shaft, and seals to prevent gear oil from leaking out of the differential. Over time, the gears, differential carriers, bearings, and other moving parts can wear out due to lack of lubrication or normal wear and tear. As differential parts wear out, you will likely notice a whining noise that may get louder or more high-pitched as you increase your speed, and this can be an indicator that the differential requires service or repair. O'Reilly Auto Parts carries the parts you need to rebuild or repair your differential, as well as complete differential and axle assemblies for a full replacement.
