Check that the Bowden cable and vaccum line to the gearbox are installed OK.

Then clean and ensure correct function of E/S and 4/5th switches.

Then think about the gearbox controller and or wiring to/from it.

All this is relevant to my slightly earlier car. Yours may be different.

Others will know better than I.
