Your transmission is the probably the most complicated and least understood major component in your car or truck. Now a days, the transmission is a combination of sophisticated hydraulics and computer-controlled electronic components.
No other single component in your vehicle is more complicated or has more going on inside than your automatic transmission.
A transmission is a mechanical component designed to transmit power from a vehicle’s engine to the drive axle, which then turns the wheels to drive the vehicle.
By varying the gear ratio, a transmission alters the levels of power and speed to the wheels. For example, in low ranges, your transmission provides more power and less speed; in high ranges, just the opposite is true. This reduces the load on the engine, while increasing the vehicle’s speed and your fuel economy.
Just as your vehicle's engine relies on the proper engine oil for lubrication, so does your automatic transmission depend on a special fluid to cool and lubricate the moving parts inside. Transmission fluid not only cools and lubricates, it also is used to supply hydraulic pressure that applies the clutches inside the transmission. This fluid is absolutely imperative to the transmission’s operation. This is why it’s important to check the transmission fluid level and condition regularly (check your owner’s manual or call us for advice) and to have your transmission serviced at least every couple of years. A Transmission Service at Transplant Transmission, Powertrain & Diesel includes changing your automatic transmission fluid (commonly referred to as ATF) using a special proprietary blend of transmission fluid specific for your vehicle mixed with friction modifiers, replacing or cleaning your transmission pan filter, replacing the pan gasket and making any possible adjustments needed as well as a performing a computer scan of your vehicle searching for any diagnostic trouble codes that have been stored.
Later model front wheel drive vehicles also incorporate another major component into the body of the transmission itself: the differential or final drive. These types of transmissions are technically known as TRANSAXLES although for our purposes we refer them to transmissions as well
Front wheel drive configuration improves fuel economy and handling, and reduces manufacturing costs. But because of the additional components in these types of transmissions, it’s generally more expensive to repair or re-manufacture than a rear wheel drive transmission when it fails.
