How to Troubleshoot a 1992 325I BMW Transmission

1. Start the engine and let it run for about 15 minutes.
2. Open the hood and pull the looped handle in the back of the engine all the way out. This is the transmission dipstick.
3. Examine the fluid. It should be red in color. If it is reddish-brown, or smells burnt, then you will need to have the transmission fluid changed and your transmission checked for any internal damage.
4. Check the fluid level. Examine the end of the dipstick. The fluid level should be between the upper and lower marks on the end of the dipstick. If it isn't, you'll need to add more transmission fluid until the fluid levels are adequate.
5. Put the car into gear. If it grinds or is hard going into gear, you will need to have the transmission serviced. Grinding gears can indicate chipped teeth on the gears. However, it is more likely that the synchronizers are damaged.
