Transmission Red Light

[joedana0502]

Does anybody know if there is a way to overide the transmission do not
shift light. The transmission will not shift. I am sure the problem is
electrical. I am parked in a place that a tow truck can't get to. I
just need to be able to back up about 100'.
Thanks for any help.

Joe,

As you have now discovered, the "do not shift" is really a "you can
not shift" light! First thing to check is to make sure the coach has
good 12v power. Check the dash gauges. If your batteries are run
down below 12v, that may be the problem. When I lost the alternators,
the batteries ran down and the do not shift light came on. Jumped it
to start the gen set and made it home on gen set/battery chargers.

Cycle the rear start switch and place in the front start position. If my front rear start selector is not just right it will give me a do not shift light. I do not have a drawing for the tranny but if it's not the rear start selector it's probably a ground related to a the speed sensor. Seems like I remember a post a long while back with the same symptom. Maybe the one who had the problem will talk.

I would try some of the test like Leroy said with someone in the
drivers seat looking at the light. when it goes off you will have a
clue to the connection that has issue. That way it wont end up a now
and again problem. A shop may just check and poke at everything
untill bychance it works. always good to learn the real cause. I
would think it easier and less bucks to find a mobile tec to look it
over than have it towed.

the allison computer is in the bay under the driver ( in the 94)
there are plugs and test ports under the shift console in the
cockpit and there is a converter modual between the atec and ddec
some place that could have issue with voltage + or ground.

grounds are my first review. I often run a cable from the battery -
to various locations to add a ground and bypass a weak one.

I always wondered if the retarder making the brake light glow could
cause an issue with the Allison computer?

Good luck, I am sure you will find it without a tow and be better
learned on the systems while you search

There should be a by pass code for that problem in the files section. It
included the "how to."

Thanks for all to good ideas. I did find out that something is wrong
with the rear starter switch. It will not start at all from the rear.
I will tear into that switch and see what I can find wrong.
Again thank for all the help.

Maybe it is something to do with Neutral safety switch? the start
terminal runs from the key to that NSS then to the starter relay
then to the starter solenoid. the Neutral safety switch proves issue
with other things like high idle and retarder functions. the rear
switch orange=power pink=ign purple=start.

I guess the switch that Leroy spoke of has a function to not allow
the Allison to be shifted when the bus is started from the rear. Do
you see the switch Leroy spoke of that makes the choice front or
rear? even the front ign runs back to that switch. I found the 20
amp fuse/brakers for the ig behind the bumper.

I had that happen to me earlier this year. Havent
been to a dealer to get it checked, but thats on
the list of things I need to get looked at before
my next trip.

You should have some flashing lights by the check
trans sw if its like my '87 PT40. If you turn on
the ignition and you _dont_ get the 'do not shift
light' AND the trans error light for a few seconds
then you have a burnt out bulb. You'll need to
find the code and go from there. I replaced mine
with a LED from ratshack...

The plug for the trans is on the passenger side of
the trans on mine, just about even with the
charger compartment. YMMV.
You can try 'exercising' the plug and see if that
work, or check voltages there.

I attached a copy of the code chart, hope it helps...
