Help and advice needed please. My 2006 facelift 6 speed diesel Accord jumped out of 5th gear on the motorway the other day and now won't stay in gear under any load whatsoever. All other gears are fine. It feels like it goes into 5th fine, no crunching or notchiness. However, I've noticed when at standstill with engine running and clutch down, I can put it in any gear except 5th.
I've had the car since 160,000 miles and it's now done 193,000 - I have no record of gearbox oil being changed. I've ordered gearbox oil and I'll change this week. If this doesn't sort it I'm thinking of just leaving it and living without 5th which isn't too bad. My questions is, do you think the rest of the gearbox will hold up? We are taking our (fairly hefty) caravan to French Alps and Ardeche in the summer - about 1600 miles of towing. The last thing I want is a breakdown or gearbox failure. The old girl took the caravan to Croatia and back last year with no problems.
Any advice would be greatly appreciated. There's lots of used gearboxes available for £150 or less but I don't fancy changing it myself. Any idea on labour time / costs for a garage to do this?
