Thanks guys. Yes peter thats an idea. I just noticed today that suddenly im getting under 3000 at 60. now touching 65 to 70 at 3000. the car had been standing for a year and things have been needing 'freed off'. Consumption is average 25 mpg with mixed motoring town and dual carriageways. Have noticed that on hard acceleration the gearbox fault warning comes on and restricts changing up. But stop, switch off and on and its fine. Im guessing nothing serious and i suspect the fluid is goosed. I got it with only 32000 mile on it. The old mots only show approx 2 to 3 thousand miles a year which must have all been very short stop, start journeys. Which i know from experience is never good for the rluid. I just dont have any expetience with jags and their "foibles"!
