Selespeed no Reverse or 5th gear.
I recently changed the gear box on my 147.
Initialy could only get 1st 2nd and reverse, according to display.
On driving the car forward gears selected seemed to be random.
Ran Alfadiag and found 2 of the sensors to be showing as shorts.
Gear selection position sensor
Gear engagement position sensor
Have reinstalled these sensors this weekend. Now no faults show on Alfadiag and car drives fine in 1st - 4th. both manual and city, but have no 5th or reverse gears.
Have tried to run configuration on Alfadiag but ends in fault, says no 5th or reverse gear.
Does any body have any suggestions.
By the way for any body changing the gear box don't believe all the stuff about having to drop the subframe.
