Despite 'lifetime fluid' claims, automatic gearboxes last far longer with regular fluid service. We perform dynamic fluid changes on ZF, Mercedes 7G/9G-Tronic, DSG and tiptronic transmissions.
For harsh shifting, delays or fault codes we test the mechatronic unit; for manual cars we replace clutch kits and flywheels.
When an overhaul is needed you get a clear cost analysis with repair vs. replacement options.
