What is the replacement interval for transmission fluid in a car?
2 Answers
Generally, the replacement interval for transmission fluid is 40,000 kilometers. It should be replaced every 40,000 kilometers of driving to avoid compromising driving safety. Additional information about transmission fluid: 1. Although the typical replacement interval is 40,000 kilometers, the replacement schedule for transmission fluid varies by vehicle model. Different models have different recommended intervals, so always refer to the replacement cycle specified in the owner's manual. 2. Vehicle owners can also determine whether transmission fluid needs to be replaced based on the performance of the transmission. For example, if gear shifting is smooth and noise-free, replacement may not be necessary. However, if shifting becomes rough or noise increases significantly after reaching 100 km/h, it's time to replace the transmission fluid.
Just ran into a Golf in the shop a couple days ago, gearshift sounded like a tractor creaking. Checked the dipstick before changing the oil - sticky like caramel. In all my years fixing cars, I've found manuals need close watching by 30,000 km, sooner if stuck in traffic daily. Automatics are trickier - Aisin's 'lifetime fluid' claim for their 6AT is rookie bait. Try going 5-6 years without a change and watch valve body deposits form instantly. ZF's 8AT is tougher, but with aggressive drivers, the pan magnet's covered in filings by 60,000 km. Worst case I've seen? A CVT owner who waited till the belt slipped - 23k RMB overhaul. Pro tip: trust the maintenance manual over used car salesmen's tall tales.
