F1 gearbox sensor function
Thought i would share the function of the sensor for the F1 that sits under our gearboxes. I think I must be the only one needing these sensors in bulk. Last year i had to replace it because of a large hole in a drive through and i did not take it at an angle.
This year i was having a very spirited drive and I bottomed the car out hard enough that the sensor got pushed in and cracked the bottom case and the sensor lightly touched the gear. The actuator was not hit.
It appeared the sensor was ok so I did not replace it.
Now the interesting part, the sensor i believe was still partially working because the F1 functioned fine under slow accelarations, ie below 6500 rpm and with the throttle not floored.
Under full throttle and above 6500 it would shift then apply the clutch for a very brief period and then release it making for a very jerky shift.
It would only do this under a full throttle above 6500 shift. You would not know it was malfunctioning under less abbusive driving conditions.
It says this nowhere i could find but this does happen.
Replacd sensor and all is perfect again.
