Keeping your BMW in top condition requires regular maintenance, and one of the most important tasks is checking the transmission fluid level. Transmission fluid plays a crucial role in lubricating and cooling the complex system that transfers power from the engine to the wheels. Neglecting to check and maintain proper fluid levels can lead to costly repairs or even transmission failure.
The 1998 BMW 740i transmission is sealed without a dipstick, requiring a lift to check fluid level via the fill plug. Slipping often results from low fluid caused by leaking seals or internal wear like clutch pack degradation. The Double-Clutch transmission uses a set of two clutches that are "wet" clutches.
The clutch discs are immersed in the same oil used to lubricate the transmission internals. The wet clutch system ensures smooth operation and engagement. BMW requires a special DCT-specific fluid, although they also label it as "Lifetime Fill".
Specifically, BMW recommends exchanging transmission and differential fluids in 1998 BMW 740iLs at certain intervals with BMW. What type of transmission fluid you need depends on your vehicle. Your car's manual provides transmission fluid service requirements.
