I've done that sensor cleaned all contacts including the gearbox loom conector. got all gears now apart from when I shift from 2nd to 3rd it misses 3rd and goes straight into 4th but then I can come down into 3rd from 4th, is this another sensor glitch or because it has had a new gearbox does it all need calibrating on the administrator. I was told maybe it would right itself but done over 120 miles but still is the same, But looking on the bright side I aint broke down and it aint got any worse. I could really do with a little help I am getting there slowly. I think!!!!
I also have the numbers flashing in reverse and 5th gears. no gearbox warning light it must have flashed that much the bulb has blown or someone got sick of it so disconnected it..lol
