Hi guys,
I cannot find this sensor anywhere in my FSM. Does anyone know what it is? Does P0705 translate to any of the codes in the FSM?
My symptoms are only apparent with the shifter in '1'. I tried it in 4LLc and 2H, same thing. No engine breaking at all. It just coasts until RPMs drop to about 800 and then it jolts in to the low gear. In 'D' it appears to operate normally.
I looked at the low range detection switch. The FSM says system voltage (assume 12V) in 4HLc and 0V in 4LLC on the A/T-ECM terminal. I'm not sure how to check that.
Any ideas about this would be greatly appreciated

Hmmm, been reading more about this. Could this be a shifter linkage issue? May be something to do with my 2" suspension lift? Also, perhaps the NSS?

Isn't that sensor on the dside of the tranny? on the end of the shifter shaft?

I doubt a linkage issue would occur with a suspension lift but bodylifts are notorious for screwing everything up.

Yes, it is. Didn't get a chance to look at it tonight. Hopefully tomorrow. From the FSM it doesn't seem to be adjustable like earlier models. I will attempt to check the continuity in the harness. Can I do the same with the switch itself? The other symptom that I noticed tonight was that ALL the shifter position lights on the dash are not working, but they all worked before. To me that's further evidence for this switch or the harness being responsible for the code.

I agree, but I'll reset the cable tension anyway, just in case
I'll report back

Finally got a chance to look at this today. I re-set the shifter rod position, but that was fine. So I removed the park/neutral position switch, took it apart and cleaned the dirty contacts inside. I went for a test drive after replacing the switch and the check engine light stayed off for a while, but it came on eventually 
Can someone please instruct me on how to test for continuity in the switch? On my multimeter under ohm, it has 200, 2000, 20K, 200K, and 2000K. I don't know what to set it to or what kind of reading I should expect. Also, I can't see the contacts with the switch on position on the tranny. I guess I'll have to test for continuity with the switch removed?
Thanks

You can use any of the scales, but for open/continuity checking, I'd use the 2000 scale. There will be some resistance even on a normal continuous circuit, but it should be low, and unless you have a superconducting circuit (and a lot of liquid nitrogen to keep it that way), you won't see zero ohms unless you are using a somewhat large range. If you see over 10ohms on any continuity check, that's a suspect contact and/or wiring harness connector.
I only have a manual up to the 95 models. Do you know your tranny model code? If its a v4aw3, I've got a chart to check the sensor for continuity.

Thanks Eddy. Yes V4AW3. Is this the chart you were talking about?
It's from my FSM.

Yes, same chart. Use the ohmeter to check continuity between the labeled terminals in each selector position. For example, in P, you should get 0 ohms between 1 and 10 and 5 and 6. 5 and 6 are the neutral safety switch, since they show continuity in both P and N. I'd pay special attention to continuity between 1 and 2, i.e., L selected.
My bet is a bad harness or a connector pulled apart, since the dash indicator uses the same harness and is not working.
edit: I looked at the 95 manual. I'd check the fuses, in the case of a 95, fuse 18. This is power to the NSS and in turn, the selector lights. Also, the connector to the TCM, under the dash, looks like it's on the frame that holds the steering column.

Thanks Eddy. Will check those things and report back
