Your vehicles transmission changes your engine’s speed and torque in relation to the speed and torque of the wheels. This keeps the engine’s output matched as close as possible to varying road speeds and loads. There are two types of transmissions on the road today: manual and automatic. The main difference between these two transmissions is that an automatic shifts gears automatically while the manual requires you to shift them yourself.
Manual Transmission
Check your owner’s manual to find out when your transmission might require a lubricant change. The level of lubricant should also be checked at every oil change. Symptoms of faults inside the transmission may include difficulty when shifting gears, grinding when shifting gears, a growling or whining noise with the transmission in a certain gear range, and popping out of gear.
Automatic Transmission
Most of today’s automatic transmissions/transaxles do not require any regular adjustments. Check your owner’s manual to see if any adjustments are required. Owner’s manual recommendations on transmission fluid changes vary considerably and may go as high as 100,000 miles or more. The overwhelming majority of transmission failures are heat-related, and automatic transmission fluid breaks down rapidly when subjected to high temperatures.
