2001 Oldsmobile Aurora 3.5 L  V6.
Repairs = GM dealer has trouble shot, cannot

Question = Dear JK, my 2001 Olds Aurora ignition
key sometimes cannot be removed. This only
happens on hot summer days here in Houston, 85-
100 deg, after the car has sat in the sun all day
long. At the end of the day I start the car normally
and drive about a 1.5 miles. Stop, put the car in
park and turn off the engine. The engine stops and
then the key will not rotate to the off position. It
stops just a little past the accessory position.
Transmission is not locked at this point. If I drive
longer (i.e. further) the problem is not present. This
problem started last summer but all this past winter
the problem did not occur once, it came back this
summer. It fails like this one out of three trips.

I have tried many tricks to figure out what is going
on and overcome the problem. I Play with the key,
shifter, brake, and the only thing that works fairly
consistently is to restart the engine, place shifter
into drive, hold brake and load engine to 1500 rpm
for 5-7 sec. Them immediately put shifter into park
and turn off engine. 6 out of ten times this works.
Otherwise I sit for four to ten minutes with engine
idling or driving around parking lot until key will
come out.

So the problem seems to have two core links, high
ambient temp combined with a very short trip.

GM dealer cannot duplicate so they say they don’t
know what to repair? Do you have any experience
with this problem or know of a course of action to
diagnose the problem?

Hello and welcome. Have had this problem with
several other cars with floor shifter, just not
specifically an Aurora. With what you describe, it
sounds like the shift lock solenoid or mechanism in
the floor shifter console is not working properly.
That may be caused by a faulty solenoid, or
possibly the adjustment of the shifter cable. With
the shifter/cable not fully in park, the solenoid will
not activate.

Usually play with key and shifter will allow it to go
fully into park and release the key. I spoke with our
transmission Tech. SF, and he agrees. He also
added that he has had a FEW worn shifter cables
also do this, which may be why brake torque of the
engine you described works.

The movement of the engine may be enough to get
the shifter/cable all the way to park. Sometimes
spilling liquid(coffee, pop, etc) can also cause a
linkage or shift lock solenoid in the floor shifter to
stick after it has been in there a while. This could be
the reason for happening in hot weather- liquid gets
sticky. If you would like to try and repair yourself, let
me know and i will try to help.

P.S. Getting the upper plate off the center console
to gain access is quite a difficult task. Very easy to
crack Let me know if you need more help. JK
