The auto on mine - '85 240 GL with 280,000km - seems to have a mix of whines and whistles. Gearbox was apparently serviced not too long ago by the local Volvo agent and seems to otherwise work ok, apart from the kickdown, which doesn't work at all... I've now just got used to the various noises. I keep the fluid clean and topped up + I'll worry about it if the car should suddenly come to a halt! However, if anyone should have some idea of the cause of these noises, I would be most interested and grateful! Kind regards, John.
