RB25DET Gearbox Worm Gear

[Black 1via RB25det swap]

Hey Guys, 

So recently I put a post up thinking I had finally solved my speed sensor issue and got the right speed sensor what my RB25 gearbox. Turns out I'm a flipping numpty and the new sensor doesn't fit and I had the right sensor all along. I know I have the right sensor for the gearbox, I know there's no problem with the sensor itself (it's sending a clean signal to the dash when manually turned outside of the box).

Problem is as soon as I put the sensor in the box and turn the engine I get no signal at all. Has anyone got ideas what it could be? Like could it be the worm gear put in back to front etc? Visual inspection of the worm gear seems fine and it's rotating when I spin the wheels with my feet and look in the gearbox at the same time.... Stumped.

The gears have to mesh. It is possible that if the gear in the box is not the right one for the gear on the sensor...... that maybe you get no rotation.

Or is the rotation in the correct direction. Do you have a mixed set, note below, the gtr33 and KA auto rotate in opposite direction to the others. Just a thought. GTSBoy knows more than I, about this subject.

Probably not true.
