Hi, my uncle got his Audi RS6 C5/4B with an issue, when he tried to engage 3rd or 5th gear the car is trying to engage it but finally goes to 2nd or 4th gear instead, I used an VAGCOM diagnostic tool and it report 2 error code about the gearbox which are :
17117 - 3rd gear
P0733 - wrong gear ratio - intermittent
17119 - 5rd gear
P0733 - wrong gear ratio
What do you think about that ? Do you think the issue is related to the valve body ?

Thanks for all

 

Sounds to me like it might be slipping
