Customer complain: Audi A6 Hybrid rough shifting and unable to shift completely after some time.
Diagnostic: Mixture of coolant and transmission fluid. If coolant mixes with the transmission fluid, it can lead to inadequate lubrication, which might cause increased friction, overheating, and eventually, significant damage to the transmission components.
Action: Complete transmission overhaul. The clutch plate are heavily damaged because of poor lubrication. O-ring, oil seal and piston are hardened as a result of transmission overheating.
