For most automatic vehicles, the manufacturers suggest that the transmission fluid be checked every 30,000 to 40,000 miles. However, unless there is a noticeable issue, such as trouble shifting, most drivers forget all about maintaining their automatic transmission fluid. What eventually happens, is that by the time that a mechanic performs your regular maintenance tune-up, [...]

Cars with automatic transmission are gaining ground in the India. Hardly a few people had heard of automatic transmission in cars a few years ago. Unlike the West, the car drivers here were fond of manual transmission more and to meet their requirements the Indian car market here was full of cars with manual transmission [...]
Now, (with caution – safety first!), shift the transmission lever into neutral. Apply the parking brake. With the engine idling, press the clutch pedal all the way, hold it down, and listen for noises. Then release the pedal and listen for noises again. There should be no loud noises at either positions. The next step [...]
There are several problems that can be resolved with an adjustment (A simple adjustment is one that can be made without removing the transmission from the vehicle.) or minor repair. If a late model transmission (computer-controlled transmissions started becoming popular in the early ’90s) is not shifting properly, it is often the result of a computer [...]
Transmission fluid should be changed periodically. Your owner’s manual should give you the recommended intervals which could be anywhere from 15,000 miles to 100,000 miles. Most transmission experts recommend changing the fluid and filter every 25,000 miles. Few transmissions have drain plugs to drain the old fluid. In order to get the fluid out, the [...]
Computer Controls The computer uses sensors on the engine and transmission to detect such things as throttle position, vehicle speed, engine speed, engine load, brake pedal position, etc. to control exact shift points as well as how soft or firm the shift should be. Once the computer receives this information, it then sends signals to [...]
On automatic transmissions, the torque converter takes the place of the clutch found on standard shift vehicles. It is there to allow the engine to continue running when the vehicle comes to a stop. The principle behind a torque converter is like taking a fan that is plugged into the wall and blowing air into [...]
