Proctor Car Tips: Transmissions

What is a Transmission?

Your transmission is bolted directly to your engine, and as the name suggests, it transmits the power that your engine makes directly to your drive wheels. Depending on your vehicle, you may have a manual transmission with a manually operated clutch, or an automatic transmission with various speeds. There are up to nine gears that work together to offer you a seamless shift throughout the driving of your vehicle. Also some vehicles are equipped with a CVT (Continuously Variable Transmission) using a system of two variable ratio gear drums to offer a seamless shift while driving.

Servicing Transmissions

Depending on the make and model of your vehicle, your transmission service periods can vary from anywhere between every 30,000 miles to every 60,000 miles. On some makes and models a separate filter is available for your transmission which will need to be replaced when changing the fluid. This filter gathers up all the particles in the fluid and stops them from reentering the transmission and causing damage to the valve modules.

Most modern transmissions are controlled electronically with a PCM (Power-train Control Module) which shifts your transmissions through a series of solenoids. On recent models, transmissions are monitored with various sensors (both input sensors and output sensors), so that any kind of discrepancies or any kind of failures can be picked up electronically and recorded in the PCM. We can then access that module via our laptop, and access those failure codes to determine what kind of problem you are having with your transmission.

Tell-Tale Signs of Transmission Issues

Some of the tell-tale signs of a failing transmission are slippage. This is when the clutch packs inside your transmission begin to slip, and the power is lost from your engine. The clutch in your manual transmission uses a friction disk and a pressure plate. These are serviceable parts that need to be replaced if you have any kind of clutch problems. 

Best Practices for a Long Lasting Transmission

The best way to keep your transmission working well and lasting longer is to service it at the regular maintenance periods, using the correct transmission fluid. The use of the wrong transmission fluid can damage your transmission, and they are costly to repair or replace. When you find yourself in need of a transmission service, make sure to go somewhere that uses the correct fluids and knows the correct procedures. If you find your vehicle in the shop, and it needs a transmission replacement, it is good to go where the manufactures "approve" replacement. This will ensure that is built by the professionals who know the vehicle.

Just like checking the oil in your engine, checking the oil in your transmission is important. Most transmissions these days have a dipstick that is easily accessible. This dipstick can be read with a high and low mark, depending on whether the transmission is hot or cold. 

Maintaining your transmission is important. Transmissions are very expensive and the labor to replace them is also costly.
