Gearbox..Gearbox...Gearbox

[Nognar]

Ladies and Gents,

Here is a tale of a problem with a gearbox, nothing new there as these fine pages have plenty of excellent content on the subject matter in hand.

The car is a 2002 D2 S8 in fine and what was fully working condition.

Its been excellent, no problems and driven as it should over the years. Car is well serviced and has just clocked up 196,000 miles.

Last few weeks when accelerating its sounded like a supercharger has been placed under the bonnet and on occasion when coming down from high speeds to stop the gearbox has clunked a little when coming to a stand still.

I thought it may be MAF problems causing the downshift annoyance and the supercharger noise may just be an old Crank Case Breather Valve on its way out so both parts have been ordered and on route.

Car drives fine, changes are smooth but this morning I came from 70 (!) to 0mph at a junction and it did not want to find a gear for a moment, then ah yes then it went into limp mode.

Hooray!

Drive to work in limp mode, switched it off and went and had lots of coffee.

On the way home the car was fine, no limp and changes OK but may have been a little jerky though that could be simply me over thinking matters.

So.

VAGCOM lappy comes out and the only error found is P0730 Gear Ratio Control Incorrect Ratio, which I have now cleared.

As many will of course correctly say this could well just be the traditional old gearbox problems on the D2 and it needs repair.

Now here comes the interesting part which makes me believe its not a traditional old gearbox problem.

The car had a complete, full works £3000 gearbox overhaul at Mackies in 2013 at 163,000 miles.

So my thoughts are this may be one of three things and I would welcome your thoughts on the matter dear D2 collective.

1) Gearbox is now an elaborate paper weight
2) Gearbox could be a little leaky and needs a fluid top up/ change
3) The MAF/ Crank case vent valve are causing pressure/ reading errors in the system that are not helping.

MAF and Crankcase valve on route so that's easy to check, I will also go for a gearbox fluid top up (With the correct fluid of course!)

Anyway.

Happy Friday everyone!
