KA24DE transmission sensor

[kazama]

Hi all, i have a 1993 240SX with KA24DE, bought a transimission, the bell housing is missing a hole for 1 of the sensor, the very last one, right next to the reverse light switch, where the housing connected to the gear box, on the service manual, it says it is a top position sensor, which is a 4th gear sensor. Do i need to plug it in ? i really search all over the net, and couldnt find an answer, some said is for cruise control, some said is a speed sensor, i really need help on this one. Thanks

you probably bought an s14 transmission. You don't need that sensor plugged in, Ive been running without one for a while now. I don't think it will effect your cruise control, I believe that works off of the vehicle speed sensor.

The only ones you NEED plugged in is the reverse and the VSS (Vehicle Speed Sensor). The others aren't really needed.

If its on the bellhousing its only for the S14 and not needed.

I think he meant at the bottom of the bellhousing where it meets the gearbox

I honestly don't know what its for. I assume it tells your car its in "overdrive" (5th gear). I don't know if it will affect cruise control either. However I do know that it doesn't have to be plugged in.

Transmission installed, car runs great, very smooth shifting, 4th n 5th gear swtich NOT plug in, CEL not on, speedometer normal.
conclusion, for S13, speed sensor and reverse light swith is a must
for S14, speed sensor and reverse light swith + Crank position switch
Thanks all for viewing.

I ran into this when swapping in an S14 motor and trans into my car. I made these pics to help people out
