How-to Adjust Gear linkage
Please note this is on a F40 box

1, Remove the mat, storage tray & gear gator.







2, Then you need to release the gear linkage there are two but could only get a good pic of 1 of them, use a screw driver and pull the black ring black (once fully done you see the blue square button rise fully up)



3, Next you need to unclip the gear knob there two tabs one each side just push them in and pull the blue ring up and fully remove the gear knob



4, Turn the gear knob 180 degrees and put it back on the stick (no need to lock the blue ring down)



There are two holes for it it slot in (I've marked where they should be)



Now you need to get under the bonnet.

5, Un-clip the ECU wiring from the battery tray (there are two)



6, Un-clip the ECU from the battery tray and carefully place to one side.







7, The tab my finger is on and the linkage my finger is pointing to are the ones we need to move now.





You need to push the linkage back while pushing the black tab in (you need to make sure the black tab goes back fully like so)



Next step is back in the car.

8, You now need to push the two blue buttons in the on the linkage (you know they have fully seated as you will hear a click).



9, Remove the gear gator and turn it back round 180 degrees.

10, back under the bonnet and pull the black tab out.



Now back in the car & run though the gears if you are happy replace the ECU and wiring and put the inside back together, If you are not happy repeat the above step until you are happy.
