Hi friends


I have a problem with an Audi Q5, 2010.
It has automatic transmission, and when we put the car in gear, it bounces. By diagnostic it appears the DTC error P17D400 - Valve 3 in partial transmission 1 mechanical malfunction.
We don't know when the transmission oil was changed, there is no registe. The car has 180000 km.

Anyone had a similar problem?

Should I change the valvoline first?

Regards
