Hi All,

Well, we were about to return home from our 2600 mile Florida trip on Sunday when the only incident of the trip occurred in our Eleganza.

After starting the engine and kicking down the choke, I engaged Drive. Easing down the campground road, I started to give her gas to get up a hill when all that happened was revving. No more forward progress! I eased off the brake and drifted backwards to the level area of the road. Trying to get a better start, I shifted to reverse--and nothing! Back to Drive and more revving until BOOM, the wheels kicked in and I made it up the hill to the sewer cleanout area. Leaving it running while I cleaned out the holding tank, I noticed the Reverse lights were on. I asked my wife to shift from park with her foot on the brake and the backup lights stayed on!

So, with holding tank empty (at least that was easy!), I got back in and tried the old "Wilson Special"---turn it off and hope everything is fine when I restart. WRONG MOVE! Now, nothing! I could hear the ignition buzzer when I put the key in, but no starter cranking. I tried "BATT BOOST", nothing! After running the scenario by my Dad (has had his GMC since '78), we settled on removing the ignition switch relay (is this the correct part name?) at the bottom of the steering column behind the brake pedal. We had a hiccup with this over a year ago after installing a new footwell. After unhooking the wire harnesses and removing the screws on either side, I pulled it out and cycled the "switch" portion back and forth and positioned it back to the "Park" position before re-installing. For those of you that have been through this, you guessed it--it started right up and the reverse light problem went away. Total panic time only 10 minutes!

Because this is the second incident with this part, I wanted to know if:

1) this has happened to anyone else? (In my Dad's 200K + miles, he doesn't remember anything like this happening to him)

2) is the part (relay switch) the likely culprit, or a part internal to the steering column? (I read in GMCMI letter #66 page 4 about trying to position the switch "up" the column while screwing it back in, but does that really solve the problem, or is it just a temporary fix?)

3) finally, is there a replacemnt part available for this switch? We ordered one from Cinnabar and received a straight switch that doesn't work in the lower column position.

Thanks everyone that can offer assistance or experiences! Other than that, the GMC drove great and our family had another memorable trip in her.....

Dave,

There's a major disconnect here somewhere: The revving engine & no going
problem doesn't seem to have ANYTHING to do with the backup lights/no
start/neutral-start switch problem.

For the first, since you don't report any more problem with it, I'm guessing
you sat long enough for the torque converter to bleed down; once you pumped
it up, it held through the rest of your trip.

As for the neutral-start switch, I have never had a problem with one,
thankfully, so I can't help. But I'm quite sure it had nothing to do with
the no-go situation.

Hi Ken,

I was thinking that the neutral-start switch was the culprit because it (the switch) was reading "reverse" while the gear shift was in "Park". That would disable an engine start, right? Did you read that GMCMI letter # 66 on page 4? I think whoever wrote that experienced the same problem. The transmission is NEW from Jeff Sirum last year and I don't believe that the torque converter had anything to do with the problem as she starts right up now and moves as I direct with the gear shift, since Sunday morning.

Not knowing what the inside of the steering column entails, from what I read in the GMCMI article there is a rod that moves from the gearshift to the neutral safety switch (at least I know the correct name now!) in which the two (gearshift and NSS) should coincide. If there is a difference (NSS in one position and the gearshift in another), than that seems to me why the engine wouldn't crank.....the NSS was telling the system that we were in gear and wouldn't allow a start.(?) Does that sound possible?

I barely know how to turn the key and get down the road, so my speculations may be completely wrong. What are your thoughts on the NSS importance and its abilities?

Thanks again for responding! I'm the first to admit being wrong, but the NSS out of position seems to make sense to me. Smile

The neutral safety switch is a common part and available from AutoZone fairly cheap. I had a problem with mine once. I was able to loosen the two mounting screws and adjust it. I have never had a problem with it since.

Dave,

The shift lever is mechanically connected to a cable at the bottom of the
steering column. The other end of the cable connects to a lever on the side
of the transmission. Selecting a transmission gear is purely a mechanical
operation from your hand to the inside of the transmission -- nothing
electrical involved. So, if the engine's running, you've selected a drive
gear, and the coach won't move, it's a mechanical problem. Period.

Now if the engine won't start, there are all kinds of electrical
possibilities, including the neutral start switch as a primary suspect.

I understood you had the engine running but the coach would not move. Then
after shutting the engine down, you couldn't get it started again. Two
entirely different problems. Then after getting the engine started, the
coach would move again. Not exactly coincidence, but still two entirely
different problems.

Now, there IS the possibility that you've got a loose connection somewhere
in the gear shift linkage that allows the transmission and the gear shift
lever and the switch to be out of sync. There's one nut at the bottom of
the shift cable, connecting it to the transmission shift lever, that can be
loose and let the column shift lever move (moving the neutral start switch),
without selecting the transmission gear you think you're in.

If you have the manual, check the transmission linkage adjustment procedure.

Ken H.

Ok Ken,

I'll check the transmission adjustment linkage and hopefully that'll cure this! Thanks for your help.

Dave, I agree with Ken H that you are experiencing two problems. Since the coach would not move in 'Drive' or 'Reverse' I would suspect an internal transmission issue. Low on fluid? Pressure too low to engage clutches? A low torque converter usually slips into gear as opposed to a 'BOOM'. Maybe Manny will enlighten us.

As Ken B experienced, an adjustment on the neutral safety switch may be all that is needed.

Thanks John, what you and Ken have said makes sense. Also, I probably shouldn't have used the word "Boom". It happened more like the "slipping" into gear that you described.

I plan on changing the transmission fluid this weekend, so I'll check the level that comes out. When the re-built trans was installed last year an overflow tube was added and routed away from the engine to the driver side frame rail. I have noticed drips on occasion from there, but thought that was due to being overfilled originally when installed. It never seemed to spill enough to alarm me, but maybe it is low.

I also found a new NSS from Autozone for $8.

Thanks again to all that have replied, all of you have been a great help to me.

Dave,

Don't depend too much on the transmission fluid level telling you anything
about your problem. If my diagnosis is correct, the fluid just drained from
the torque converter into the transmission. Some transmissions, because of
a minor flaw (I don't know the details), will allow that to happen. The
longer they're idle (not running), the more likely it is. When the fluid's
pumped back into the torque converter and normal operation's returned, so is
the fluid level. Probably the way to check for this is to check the fluid
level when the engine's just gotten cold. Then check it again a day, two,
... , n days later. If it's high later, the only place the fluid can have
come from is the converter. QED

Hearing your description, I think they are related. It sounds like your gear indicator, neutral safety switch and actual transmission gear are not aligned. after 40 years, how could these mechanical linkages still be.

i.e. if your indicator and actual position where one position off, when you had no drive at the bottom of the hill, you where really shifting between P(before the paw engaged so it would roll) and neutral. When you got to the dump, the trans was in park but the NSS was in reverse. I bet if you had put it in R it would have started.

just my 2 cents

good luck,

Todd

Dave,

Why are you changing the tranny fluid? You stated that the transmission was "new".
Unless the coach is your daily driver you can't have enough miles (not likely even if it is the daily driver) on it to require a fluid change- unless you've overheated it.

If it ain't broke don't fix it.
