i have just bought a 2.2cd auto and done most of the service including coolant but cannot see how to drain and refill the auto fluid , car started to lose gear in fourth and go into manual mode if i stop and restart the car if works fine

Supposedly sealed for life, but in reality needs doing every 70-80k

I believe there is a guide in Maintenence Guides, but basically its taking off the autobox sumps.

can you tell if the coolant system only having water in it and maybe very old antifreeze would kill the autobox oil has built in oil cooler on the rad

Will kill your headgasket

Hi, I have the same car. I've had so much trouble with limp mode etc but sorted it by buying a code reader and understanding the problem. In short the gearbox is sealed but I drained it of oil from the drain plug 13 mm spanner. I then undone the sump gave it all clean up. But I found you cannot top up all in one go. I get as much oil as I can in, without it all pouring out again. I then tighten up the plug start the engine slowly drive half a mile and repeat the process until I match the oil volume Ive taken out. However if you have a preasured pump this may work better. That's how I changed my gearbox oil, and I get smoother changes now.

cheers will be my job on suday where is the drain plug

I've just finished a how to guide on this very topic. It's in the test section at the minute. there's no pics yet, and mine's a 3.0 litre ar25 box, don't know what yours is but it might be helpful for you.
