sounds like maybe they forgot to put the reluctor rotor ring back on the output shaft.

pull the tail housing and see if it's in there.

You don't have to pull the housing - just remove the VSS and you will be able to feel the reluctor ring with your finger. If it is there then use a screwdriver and see if it is tight-just don't force it if it is.

should it be tight or kind of loose?

**redss70396** · 11-18-2010, 03:17 PM

The reluctor ring should be tight -I think it is a press fit.If it feels loose when you check it with your finger or a screwdriver something is wrong. Can you feel it with your finger thru the hole ? What do you mean kinda loose ? It has to be solid on the shaft .The reason I say this is I just did all this stuff this week with the help of the above guys.Also if it is tight did you ohm the sensor ?

that was the problem speedo worked fine up to about 110 thats when it stopped shifting.shifted into 2nd fine but never tried to shift out of second. seems like a shift solenoid to me. is that what everyone else thinks
