Archived from groups: alt>autos>dodge>trucks (more info?)

Well Ive had this problem ever since I purchased the truck new in the
winter of 1997. If it gets any colder than -25C I end up with no
overdrive.This has been on trips lasting over 2 hours. Today it is a
rare -40C...CRAZY COLD! I know Im not the only one complaining about
this problem.There is some improvement when the block heater is
plugged in. The colder it gets, the more likely there wont be any
overdrive.There is no shortange of cold temps in Canada unfortunately.
Has anyone come up with a solution?

I don't have a solution but I've got the same problem with my 2002 ram.
It seems as if the fluid has to reach a certain temp before the control
module will let overdrive function. So I let it warm up longer on the crazy
cold days before I leave home, but the temps in Tennessee stay a little
warmer than they do in Canada so that won't help any. I hope you find your
solution.

Date: Jul. 7, 1995

Models: 1996 (BR) Ram Truck

1996 (AB) Ram Van/Wagon
1996 (AN) Dakota
1996 (BR) Ram Truck
1996 (ZJ) Grand Cherokee

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH RWD
TRANSMISSIONS 42RE, 44RE, 46RE, AND 47RE.

Discussion:

In ambient temperatures of minus 5 degrees F and below, the Powertrain
Control Module (PCM) will electronically inhibit the transmission from
shifting into overdrive. This will protect the transmission from damage
if the automatic transmission fluid begins to freeze. This is a new
feature for the 1996 model year.

The PCM will allow overdrive operation once the ambient temperature has
risen approximately 7 degrees above the temperature the transmission
overdrive was inhibited at, or an ambient temperature of + 2 degrees F,
whichever occurs first.

NOTE: THE PCM USES A DIFFERENT TEMPERATURE SENSOR TO MONITOR THE
OVERDRIVE DISCONNECT THAN THE OVERHEAD CONSOLE. DO NOT ATTEMPT TO
MONITOR THE OVERDRIVE DISCONNECT WITH THE OVERHEAD CONSOLE.

I have the same problem with my '99 Dakota. I was worried unitl I
read in the owners manual that the transmission is designed not to use
overdrive in the cold weather. But even after it warms up it still
wouldn't upshift. What I do is drive until the temp gauge reaches
normal, then pull over and stop. It seems the transmission wont
upshift until it has downshifted after it's warmed up. Hope that
works for you.

Thanks Jerry!

That info also appears in everyone's owner's manual. As a further point, it
is the transmission temp that is monitored, NOT the engine temp.

I have also experienced a similar situation. My 2000 Durango 5.9 insists on
locking out the O/D whenever ambient is below -20c.

After driving about 3 to 4 miles down the highway, at 80 kph, (following a
brief warm-up time of about a minute), I simply release the throttle, blip the
ignition key and O/D re-appears (No, it hasn't reached operating temp yet and
ambient is about -30c).

Incidently, I can already hear the hue and cry about: an unsafe pratice,
potential loss of vehicle control, etc., etc..... so in order to save time,
consider it already acknowledged. I'm not suggesting that ANYONE adopt the
same method but merely stating what works for ME, just as a matter of interest.

Mike, isn't there also some issue with transmission drain down (for
lack of a better term) that is best cured by sitting at idle in
neutral for about 30 seconds to a minute? Leaving the vehicle in
park doesn't cure the problem?

Symptoms are that the vehicle won't move for several seconds after
placing it into drive or reverse if the vehicle has been sitting for
several days.

Yes, this occurs infrequently especially after being parked a day or two.
Parking slightly nose up exacerbates this condition.

FWIW, my Torqueflite guru Pat Blais (206-365-1966) informed me that TFs fill
faster when in Neutral than when in Park. I've noticed that w/ my '77 D200.
