Right, drove it up onto some blocks earlier, chocked the wheels and left it a bit for the susension to settle(sometimes it vents), about 20 mins later went back to it checked looms, battery etc. all looked fine.... what i`m leading upto is this- While the motor was lifted at the front would atf run to the back of the box/sump and indicate for a while that levels were fine? Reason is, i let he motor back onto its wheels, started it, no fault... went for a drive all fine. So i headed ino town, halfway there fault re-appears,could the atf have worked into the system again and shown low levels, therefore causing the fault????
