how long has this problem been happening? Is it getting progressively worse? I dont want to worry you but i have read posts about auto boxs slipping and further driveing has only made the problem worse, sometimes terminally for the box. It is a seperate unit to the engine and has 2 oil sumps running dexron 3 oil. You will need 2 gaskits and 5 or 6 litres of oil. Keep any left over for further top ups. Very low miles, so i worry if it has leeked oil out, any red/brown stuff on the drive or under the car?personally i would not want to do any miles until the level has been checked at the very least. There is a guide in maintenance section. Print it off, and take that and the parts to a local mech. Dont go to vx for the work, just the parts. They will take the piss! The first place to start with most auto box probs is the oil level in it. Do that and go from there. Hope helps. Good luck.
