Need VSS help

PreviousPage 2 of 2

Thanks for sharing your results.  Glad that worked.  It's a great feeling getting it on the road for the first time.

Needless to say, there are some small differences between the systems and their display formatting.  Your field 4 has "Other" or "4LXOe", whereas my system calls that field 4LXOe and the selections are "On" or "Off".  As for what "Other" or "Off"  signify, I'm not sure.  As a guess, I would venture to say that "other" tells the ECU that there will be no speed signal and would deactivate the ECU from trying to send shift signals to the trans.

91jeep, I would recommend replacing the VSS sensor first.  It's an easy replacement.  Then you can, at least, rule out a sensor issue.

On a related note, does anyone know if it's possible to "bypass" the VSS control?  As a work-around, is there a way to program the ECU to control shift points by throttle position and RPM?

I also have a VSS signal issue, but mine is related to the adaptability of the wiring harness to a first-gen 4L60E.  I have a first-gen 4L60E (similar case to 700R4) that has a different VSS connector than the 2nd or 3rd gen transmissions.  I searched high and low and cannot find an adapter.  I called FiTech a few months ago, when I was installing, and they said that they don't make an adapter and if I cut and splice-in the correct connector into the VSS wires, I would void the warranty.

 

Have you found this some guys are saying they work with the older tranny speed setup and Fitech. I looked at it because I have a 700R4/4L60 later model but don't use VSS mine is manual valve body.
