Chery Tiggo 7 Pro gearbox oil service interval neglect fault
Rough gear changes, slipping, and shudder developing after 60,000-80,000 km on vehicles where the dual clutch gearbox oil has not been changed. Chery specifies a 60,000 km gearbox oil change interval for the 7DCT but this is often missed at independent services. Using the correct Chery-specified fluid is critical — generic ATF causes clutch pack damage.
