PREVENTATIVE MAINTENANCE
TRANSMISSION FLUID &
GEARBOX SERVICING.
Transmission fluid is the lifeblood of your gearbox, keeping thousands of precision gears, clutches, and hydraulic valves lubricated and cool. Regular fluid servicing prevents costly breakdowns and keeps gear shifts smooth.

Why Does Transmission Fluid Need Changing?
01
Busting the "Sealed for Life" Myth: Many vehicle handbooks describe automatic or manual gearboxes as "sealed for life" or "maintenance-free". However, in automotive terms, "lifetime" typically means the expected factory warranty period (often 5 to 7 years or 60,000 to 100,000 miles).
The actual manufacturers who build the gearboxes (such as ZF, Aisin Warner, and BorgWarner) recommend routine fluid changes because transmission fluid undergoes extreme thermal cycles and chemical breakdown over time.
02
What Happens as Fluid Degrades?: Over thousands of miles of urban driving, towing, or motorway cruising, transmission fluid gradually loses its lubricating properties:
- Viscosity breakdown: Heat thins the oil, reducing hydraulic line pressure needed for crisp gear changes.
- Debris accumulation: Microscopic friction material and metal particles build up, clogging fine filter screens and sticking valve body solenoids.
- Seal hardening: Depleted additives cause internal rubber seals to harden and weep, resulting in low oil levels.
