What is an OEM Transmission or Engine?

Replacing an engine or a transmission is a huge expense, and you want to be sure you are getting the best replacement for your money. You are told there are Original Equipment Manufacturer (OEM) and aftermarket parts. It’s important to understand what these parts and their differences are, especially if an insurance company is involved.

What Is An OEM Part?

According to About Money, OEM parts are made by the automobile manufacturer. Ford, Chevrolet, Toyota, and other manufacturers make the original parts that are in the car when it comes off the assembly line. When the car is being assembled, if the manufacturer installs Bosch fuel injectors, Exide batteries, or Auto lite spark plugs, they are considered to be OEM parts on that car because they were original. If, however, the car manufacturer used a different brand of fuel injectors, then Bosch would be considered to be aftermarket parts. All determination is made by the manufacturer at the time of assembly. While an OEM engine or transmission will cost more than an aftermarket model, you can know it will fit perfectly and function exactly the same as the one being replaced did when it was new. You can know that your replacement parts are identical to those that came in your car when it was manufactured at the factory.

The Difference Between OEM and Aftermarket Parts

According to Bessler Auto Parts, there is a wide range of aftermarket parts manufacturers, which results in varying quality. These are generic copies of original parts and don’t fit perfectly like OEM replacements do. Aftermarket parts are cheaper to buy. The companies that build them have not invested millions of dollars in research and development. If your car is involved in an accident and the engine or transmission needs to be replaced, many insurance companies will only pay for an aftermarket replacement. You always have the option to pay the difference in price between the OEM and the aftermarket part.

The Choice Is Yours

Knowing the difference between the two types of replacement parts makes it easier for you to choose the one you want. If money is an issue, go with the aftermarket manufactured part. It will carry a full warranty because it is brand new. If you want the OEM replacement, you must get it through the car dealership.

Both replacement options will have your car back on the road and running great in no time. You decide which option is best for you.
