I replaced mine last week! It was a right mother to do but now it's in, all the dash lights have gone out (as has the Traction light) & all is working fine. I replaced the pin with a long screw slightly thinner than the original pin (I removed the threaded part). I left the head of the screw on so it can be removed more easily if it needs to come out again (see pics).

It's by far easiest to remove the sensor/pin from underneath. I smashed the pin-hole part on the sensor with a screwdriver/hammer so I could get more of the mole-grips on the pin. It was a wrestle but it comes out with some WD & a twisting/bending motion. Don't worry about knackering the pin as you won't be using it again.

I also used mole-grips on the sensor (tight) as close down to the gearbox as possible then twisted a few times before tapping with a bolster + hammer (as close to the mole-grip where it is tightened to the sensor). Just a few taps & it was out (after a few twists).

After greasing the rubber rings on the new sensor, it went in easily. It's not as tough a job once you know how to get the pin/sensor out. You'll only need to jack up the nearside of the car (I used 2 axle stands on the chassis at the car centre, one behind the other to be safe).

Good luck...




Get your grips tight like this when it's still in the gearbox & tap out with a bolster + hammer.
Twist the sensor a few times first to loosen it...
