So here's one I've not heard of yet.

Was out with the car, Got a dash full of lights and suspected it was just a wheel speed sensor (which it was as confirmed by the diagnostics machine). No problem, ordered one and carried on.

Now FF>>> a day or so and I'm pulling into a slip road so changing down the box....6th-5th..(auto blip)..5th-4th (auto blip)..4th-3rd....no gear engaged and the revs bouncing off the limiter. Tried a full press (a stamp) of the throttle pedal but nothing.
Switched car off and re started and all fine again.

Anyone seen this before and anyone have any idea what the issue could be?
Thoughts are,

SMG Pump issue? (its original and 78k miles old)
Throttle Position sensor issue?
ECU / brain confusion with downshifts and wheel speed sensor all getting mixed up with one another?
Something else?

Thanks
