Hi folks,got a vectra c 2.2 litre petrol,Gearbox is okay to start with but then stays in fifth gear,if I push it over into manual mod it still stays in fifth,turn engine off and restart,in manual mod no fifth gear but in auto its okay briefly then does it again,management light is on,fault is sticking clutch,torque converter,this only started after fluid change.
No contamination appears to be present.Dealer is saying gearbox fault as only one fault code is ever present,is he right.
Have asked local garage who did first fluid change to drain and refill again with genuine VX fluid,they have said they will remove valve chest and clean it as well,does that sound plausible.
By the way mileage is 80,000
