how many teeth does the reluctor on a 98 sixspeed have. after hearing that I would notice the differance if I had on I would like to fabricate something up

Whats a reluctor wheel?

reluctor wheel is the big sprocket looking thing that is on the cam. It tells the motor where it is in order to fire the coils.

i think he means the reluctor wheel in the transmission, for speedo output. i think its 17 teeth.

Yeah it's 13 or 17 not sure. If you are doing a swap into a truck you need a 40 tooth reluctor for the factory ABS to work right if you are into retaining it if you have it. Jags that Run make such a piece.

I did mean the reluctor in the trans. I am just installing one for the pcm's sake not for any speedo

40 tooth reluctor wheel and pick-up are available from J.T.R(jags that run). About $170.00 I think. Their wheel bolts between propshaft flange and pinion flange(sandwiched between the 2) and saves taking `box apart.

Nope wrong part the one I'm talking about is the reluctor that replaces the one in the transmission. The part number is like T56-002 or something like that. It only costs like $75. Anyways, he isn't using it for the speedo, just the PCM 's sake so he doesn't need anything like that.

that reluctor wheel is on the crank, not cam

the trans uses a reluctor wheel as well. at least from my understanding. a reluctor wheel is for anything that uses a magnetic pick up to keep track of rotating objects. the teeth disrupt the magnetic field. the cam and crank both use one as well. my speedo pick up is gear driven so it produces a voltage rather than just a pulse. so I can't use that. I have been told that having speed input to the PCM improves performance. I also need to figure at what point the pick up is located at. I am assuming on the output shaft of the trans.
