Automatic transmission Volkswagen Golf 4
The Volkswagen Golf 4 was equipped with two main types of automatic transmissions:
* 4-speed automatic transmission with torque converter (01M)
* 5-speed automatic transmission with torque converter (09A)
4-speed automatic transmission (01M)
* First introduced in 1999.
*Contains 4 forward gears and one reverse gear.
*Uses a torque converter to transfer power from the engine to the transmission.
* Controlled using a mechanical gear selector with four positions: P, R, N, D.
* Installed on Golf 4 models with 1.4-1.8 liter engines.
5-speed automatic transmission (09A)
* First introduced in 2001.
*Contains 5 forward gears and one reverse gear.

Features and Benefits
* Smooth Shifting: Automatic transmissions provide smooth shifting, reducing jerking and jerking.
*Easy to Operate: Automatic transmissions are easy to operate and require less concentration than manual transmissions.
* Convenient driving in traffic jams: Automatic transmissions are especially convenient when driving in traffic jams as they eliminate the need to change gears frequently.
Problems and maintenance
* Torque Converter Wear: Over time, the torque converter can wear out, causing slippage and loss of power.
* Electronics Issues: The electronic gear selector in the 5-speed automatic transmission may be susceptible to wiring and electronic component issues.
* Delayed maintenance: Failure to promptly replace the transmission fluid and filter may result in damage to the transmission.
Recommended Maintenance
*Transmission Fluid and Filter Replacement: Replace transmission fluid and filter according to manufacturer’s recommendations. Typically this should be done every 60,000-100,000 km.
* Computer Diagnostics: Check regularly for trouble codes and other transmission problems.
*Checking the transmission fluid level: Check the transmission fluid level using the dipstick. It should be between the “MIN” and “MAX” marks.
* Monitoring the Torque Converter: Look for any signs of slipping or loss of power, which may indicate torque converter wear.
*Follow Factory Recommendations: Always follow the manufacturer’s recommendations for transmission maintenance, including intervals for changing fluid, filter, and other components.
