The auto 'box in the Disco is giving me problems. It had an oil change last service (96,000 miles), and has at least two more prior to that. It drives fine, but if you stop, select reverse, reverse a bit, and then back into drive, the box goes into limp-home mode - which is third gear ! - and the M and S lights flash. If you stop the truck and restart, the problem goes away until you next attempt to use reverse.
The problem is more likely to occur on cold mornings, so I thought that maybe my man who did the last service used a different grade of ATF - but it's the stuff he always uses.
I'm guessing that there's a pump somewhere for the box hydraulics - is the pump within the gearbox, is it something that can be tested by a specialist firm, or am I looking at a new/recon box ?
BTW - Nanocom doesn't show any faults, but then I don't think it's got the ability to interogate the autobox ECU :(
Any thoughts ?
