Hi
2001 S-Type, 3-litre automatic, 76,000 miles
I'm hoping someone can shed light (offer a solution!) to my gearbox problem. The 'gearbox fault' warning is intermittent and only manifests itself on motorway driving, not around town.
I can go for miles at a steady 70 but when I slow down or stop, say to exit the motorway, the warning comes on and the gears won't drop down any further than third or fourth gear until I pull over and switch off the engine, which 'resets' the gearbox. I've had the sump/filter and a solenoid replaced about 1500 miles ago, and this seemed to improve matters, but just recently the warning has appeared again.
I'm wondering why the gearbox resets, and works normally, after I switch off the engine for a few seconds - is it an electrical, hydraulic or mechanical problem?
I'm tempted to get my local indie to swap out the gearbox for a reconditioned one at £1500, but if there's a simpler (cheaper) solution I'm hoping someone can point me in the right direction.
Thanks in advance!
PS: I'm also getting the engine warning light come and go.. not sure if it's related though
