Transmissions

The transmission works with the engine to provide power to your car;'s wheels. Whether automatic or manual, the transmission plays a major role in the overall dependability of your car. Make sure to check it at the first sign of problems.

A transmission/transaxle keeps the engine's output optimally matched to the speed and load conditions. The torque converter, connected to the automatic transmission/transaxle input shaft, connects, multiplies and interrupts the flow of engine torque into the transmission. Universal joints connect to the driveshaft to transmit output power from the transmission to the rear axle on rear-wheel-drive cars. Universal joints also allow the driveshaft to work at an angle.

Automatic transmission fluid serves a multitude of purposes. It cleans, cools, lubricates, transmits force, transmits pressure, inhibits varnish buildup and continually protects the transmission. There are several different types of automatic transmission fluid. Reference your owner's manual for how they should be used.

Wear and tear on the transmission can be influenced by:

Driving habits
Towing or excessive loads
Operating conditions
Condition of the transmission fluid
Frequency of regular maintenance

Symptoms are slipping, hesitation, bucking, grinding gears and difficulty shifting.
