Peugeot state that the AT fluid is not a service item and never needs to be changed. Ok, Peugeot know more about cars than me but to my mind this is a risk given the price of a replacement gearbox. I know you afvocate changing the engine oil more frequently than manufacturers recommend but what are you views on AT fluid changes?

My car is a 2008 model and has covered 22k miles. What would you suggest would be a suitable mileage to change the fluid?

Many thanks.
