Basic service kit for performing a drain and fill on 5-speed and 6-speed manual transmissions
This kit is designed for BMW manual transmissions including the S5D250G, GS6S37BZ, S6S420G, and S5D320Z. It includes two quarts of Red Line D4 transmission fluid and two Genuine BMW drain/fill plugs, which must be replaced with every service.
A drain and fill service is one of the easiest forms of preventative maintenance you can perform. Over time, transmission fluid breaks down, leading to excessive notchiness and poor shift feel—especially in colder climates. Performing regular fluid changes improves gear engagement and protects internal components.
Recommended interval: every 48,000 km (30,000 miles) for optimal lubrication and performance.
Manual Transmission Fluid
Manual transmission fluid is a specialized lubricant that reduces friction between internal gearbox components, enabling smooth gear changes. Failure to replace it regularly can lead to serious drivability issues.
Failure Symptoms:
Difficult shifting (hard or notchy gear changes)
Gear slipping (engine revs without proper acceleration)
Grinding noises (especially during shifts, indicating gear wear)
