I have a 2003 V-6 (2 wheel drive) 4runner with 30,000 miles and very
light use. Today the 3rd gear disengaged and the engine rev'ed and the
2nd kicked in. 1st and 2nd are fine and the oil is ok as well as clean
with no oder.

I understand that there are 3 solenoids to control shifting. Question
is, are there any breakers/fuses or any other electrical device to
control this?

Might also note that the car is garage kept, no rats ot mice chewing
on wires, I looked, it is clean. Any ideas, HELP?????

I believe that the V6 4Runner has a 4 speed automatic transmission. Are you
sure that it was 3rd gear and not overdrive or the lockup torque converter
disengaging? When you say that the engine rev'ed, how high did engine RPM
go before the transmission re-engage?

If you now have just first and second gear, a tripped breaker or fuse is not
the cause.

There is a fairly lengthy diagnostic process, involving manual shifting,
checking shift solenoid operation, stall tests, taking line pressures, etc.

If your vehicle is still covered by the 5 year, 60,000 mile powertrain
warranty, the easiest fix would be to take it to a dealer for diagnosis and
repair.

Thanks ray, This is my wife's can and I thought it had 3 forward gears
but it is the top gear that went. It does not have OD, or at least not
like my 98 does. I am taking it real slow to the dealer tomorrow (20
miles at 3000 rpm or less, around 35mph). As far as the rpm's, it just
goes out of gear at around 20-25 mph more or less and I'm guessing by
the sound, didn't look at the tach, kicked back down around 3500rpm,
maybe a little less.

4th gear is overdrive ("OD").

Hopefully, the problem is something simple like a solenoid.

Good luck!

Is it under warranty?

"Is it under warranty?"

The car is a 2003 with 30,000 miles on it so it should be covered,
however, what if it was a broken wire outside of the drivetrain
causing the problem? Do they say, "that is not part of the warranty",
we will see.

It depends on why it's broken.

If the wire moved and broke from fatigue, or wasn't properly assembled,
of course it's a warranty repair. If there are clear signs on the
bottom of the vehicle of off-roading, some sort of road debris damaged
the wire, or an aftermarket parts installation caused damage, it's
another story.

Remember, debris damage is often covered by insurance, so if there is
some sort of major damage underneath, you have the option of claiming
it. My company had a two-way radio installation company drive screws
through a wiring harness, preventing a vehicle from shifting. This
repair was not covered by a warranty, but the radio installer paid for
the repair.

The reason why I ask, is that I've been treated well for warranty
service (especially by my local Toyota dealer!), and it's often not a
good idea to do anything other than bring it back as a first step when
the vehicle is still warrantied. Messing around with it or attempting a
home repair often isn't good for the ol' argument.

Let us know what they say.

Yesterday, I gave my wife instructions on how to drive the car up to
the dealer. We took off with me following and after about five miles,
I called her and asked how it was going and what the rpm's were. She
replied with, "it runs perfect and is in drive gear". We got to the
dealer and told them it ran ok and also asked them to do an oil
change.

The only thing I did from the day before, was to go under the car and
wiggle the connector to the transmission. So I asked them to pull it
apart and check it to see if any contacts were lose. I know form
owning a marine business for more than 20 years, that it is hard to
fix things when they are not broke and Toyota agreed.

Well, at least my wife is savy on the problem and if it happens again,
she will drop it to 2nd and nurse it home. I left it with the dealer,
that if it happens again, we will leave the car with them and they can
drive it for a week or so. Has anyone else experienced this problem.
Keep in mind also that this is my wifes car and is treated like a
baby, never driven off road.

THIS IS WEIRD! OK, no luck with finding the cause of the loss of drive
gear but today the engine light came on, geez, what now.

I called Toyota and talked to the shop guy. (note, they removed and
replaced the transmission connector, changed oil/filter and also the
air filter) He asked me to look at the air intake box to see if
someone had left a hose off, nope, ok. He said bring it in so he would
scan it and went on to say, "it could be an oxygen sensor or
something". That got me thinking, there is another connector right
next to the transmission connector and the wires are in the same
harness. Could there be a problem in the wire harness, or could they
have disturbed the wires somehow? It is a bit tight there.

Then I also thought about the air filter and did some looking around
and found that there can be problems after an air filter change with
the Mass Air Flow (MAF) sensor. I begin to think, maybe they got a
little dirt on those small thermistor wires in the sensor, well maybe?
I think at this point, I will look into it first as I do have good
instructions for cleaning the sensor. Open to comments.

Without scanning for trouble codes, any checking and cleaning will be a shot
in the dark. The trouble codes will point the technician to the circuit to
check.
