The patient: 1990 Jeep Cherokee, 6 cyl, auto, 4x4
The symptoms: Won't shift out of 1st gear.

Fluid/filter are clean. There was a possible kickdown cable issue, but that's been fixed with no change in the symptoms.

There are 3 solenoids on the valve body; two on the side and one on the rear. Do these have anything to do with the shift pattern, or do they have other functions?

The park/neutral switch on the passenger side; does this have anything to do with the shift pattern? Doesn't seem like it would need an 8-wire lead on it for only part/neutral. Of course b/u lights on are in too, but 8 wires? Its almost gotta be tied in to something else.

I'm hoping this is an electrical issue, partly because the fluid is so clean and partly because I don't want to give my extra transmission to my brother-in-law. Any ideas or suggestions are very much appreciated.

Thanks,
Anthony

A bad, MLPS, manual lever position sensor can cause this as well as a bad speed sensor can do the same thing. Both are accessible from the outside of the transmission.

The good news is that it probably is electrical. Our local trans shop can scan the trans to see why it is not shifting. I would not try to drive it too much until I found the probles as I would not want to cause further damage.

A little further information:
The neutral/park switch tests correctly as far as continuity in the various gear positions as specified in the Haynes manual.

There are some other electrical issues, things like the clock and check engine light that don't work. This is part of why I hope the whole thing is electrical-related.

This model also has the PowerShift/ComfortShift toggle switch option. Does anyone have an electrical schematic and description of components for this thing?

Thanks again,
Anthony
