Transmission service
Transmission service is the maintenance of the gearbox, including transmission fluid replacement and, where applicable, filter change.
What it means
Transmission fluid lubricates gears and bearings, transfers heat away from the gearbox, and in automatic transmissions provides the hydraulic pressure that engages clutch packs. Like engine oil, it degrades with use and absorbs particulates over time. Manual transmissions usually need fluid replacement every 100,000 km or so. Automatic transmissions vary widely by manufacturer: some specify a service interval (often 60,000 to 80,000 km), others claim lifetime fill, which in practice often means lifetime of the warranty rather than lifetime of the car. For European cars, especially those with dual-clutch automatics like Volkswagen DSG or BMW DCT, transmission service intervals are critical and skipping them leads to expensive mechatronic and clutch-pack issues.
Why it matters in Singapore
In Singapore's heavy traffic, automatic transmissions work harder than they would on European motorways, with constant low-speed shifting and heat buildup. That makes the manufacturer's lifetime-fill claims especially risky here. A more conservative service interval is one of the cheaper ways to extend the life of an expensive transmission.
How Revol Carz handles this
Revol Carz Garage handles transmission service for European marques as part of standard servicing, using OEM fluid and filters. We confirm the correct fluid type against the owner's transmission code before the job, and we drain through the gearbox properly rather than relying on a top-up alone.
