Pontiac Montana Transmission Problems

in Pontiac
We need help and we need it fast. I hope someone can shine a light on this delema. We just bought a 99 transport in April of this year.I am primary driver as my husband works out of town. Anyway, in April when I drove on the highway, the transmission was straining to shift then it snapped into gear. My husband said, you just need to get used to it. Well when he drove it on his days off he noticed the problem too. We took it to a GM dealer who found a code and said the fluid was burnt. the dealer we bought it from went half on the bill and had a *good used * transmission installed. This was June 12/06 and we got a 90 day warranty. Right away we noticed the gear indicator lights would go off while driving. Sometimes they would come on other times not. Sometimes a bump would bring them back. I noticed the long shift again as well as shudders and a howling sound when you reverse.
I spoke to a mechanic and he said to have the computer checked out. It is now back in the shop and I am waiting for word on it. Can anyone relate to this or offer some sound advice? It would be very much appreciated.
Thank you

That is what we thought too. Now we are wondering if maybe it is some kind of warning that something is going on within the transmission. We used to have a Dodge Caravan . A couple of times all the indicator lights under p r n d 1 2 etc would come on all together. Then we started having transmission problems with it.I don't remember what it was but it was something expensive to fix.
I hope you have similar luck fixing your problem.
It is back in the city at the shop that did the original work. They have a transmission specialist so I hope he can figure it out.
I hope it is that simple too, thanks
Actually they ran a host of tests and said the transmission is OK. The dealer is getting it into another shop Mon. to have the electronics tested. he said the mech told him he thinks it is misfiring and that is why it seems like the transmission is not shifting. I asked what misfiring meant and he said something within the computer that tells the trans to shift etc.If that is the problem, who knows what it will cost.
The dealer is being great, the van has no warrenty but they are covering at least half of the repair cost.
Let me know if your mechanic thinks thats it too.
I have 03 montana and it has the same issue as yours.
Shifts 2 & 3 are kicking late, plus mine has the radiator
coolant is getting oil leak. I would appreciate if any one
can help in these problems. rebuilding the Trany is expensive. Any thing I could do before I run into deep bocket delima?
This is my first time here & it's very informative.
Thanks to you all who's trying to help.
Go to #20 by deestes, he and I had the same problem and got the same solution. Ours was the Pressure Control Solenoid. AS for the radiator, it sounds like you may have a seal leak at the manifold. I took mine to the mechanic and asked for a check of my Pressure Control Solenoid, you may find your solution to the other problem in the process.

MY WIFE AND I DRIVE FINE IN THE CITY BUT WHEN ON THE HIGHWAY OR OUT OF TOWN THE CAR SEEMS TO DISENGAGE 3RD GEAR I THINK. IT SOUNDS LIKE AN ENGINE REV AND THE CAR DOES NOT MOVE WE JUST COAST. ALMOST TO A DEAD STOP THEN IT ENGAGES. IS MY DRIVE GEAR GOING? ANY WAY TO BE CERTAIN CAUSE THE TRANSMISSION GUY SAYS I SHOULD JUST REPLACE IT. PROBLEM IS HE HASNT HAD ANY BUSINESS IN AWHILE AND I THINK HE MAY BE OUT FOR A BUCK. SO ANY WAY TO CHECK. THE CHECK ENGINE LIGHT COMES ON BUT AFTER THE CAR SHIFTS NORMAL AGAIN IT SEEMS FINE AND GOES OUT. SO WHO CAN SOLVE MY MYSTERY? :surprise:
I had same issue with 2003 Montana.
Shift delay or hard kick on 2 & 3 shifts.
Specially uphill very hard .
check on climbing hills.
Also check the over drive..
Switch from Drive to #3 & see if there's any changes.
It runs on the highway but the inner city
stop & Go is the problem.
Ask one of the chops to check any error Codes
of the tranny. ( 0742 ) is what mine shows.
Good luck.
Let me know if you find solution .

Takr care. :confuse:
I due add lucas to gas @ fill up (4 ounces) and have an increase of 1.3 miles per gallon.
Do not ever add any oil additive. I have used Mobil 1 since 1979 and Redline is better. Amsoil gets 3rd place and with the exception of a couple the rest are not true synthetics and are petroleum based and are strictly for suckers. Changing your oil is more important then brand loyalty but Mobil 1 will make you sleep better!
Does anyone know the best response to this issue?
The tranny's wear out at 115. Maybe get by longer but how much?????
Sensors on the pipe are main culprit for misfiring which can also cause some tranny like problems.
Full tune up with plugs, ignition, fuel filter, etc... is also important.
A complete tune up and new pipe with sensors should do the trick, but tranny will wear out. Use additive and drive cautiously and you will be many more months out of it, but don't forget, it is a GM mini van, not even close to my Honda Odyssey....
Does anyone know of a TSB that would apply to a 2003 Montana transmission that sounds like this? If so, what is the number of the TSB? Also, if you know, what exactly is the "upgrade"?
In my case, this leads to even more questions. Because I have bought my 2003 Montana used, within the last couple of months, I have very little idea what kind of history it has had. Since it was built around May 2003, I expect that it has the new intake manifold gasket. If the engine made it this far (about 130,000 km) without an intake manifold gasket problem, I think I can trust that it is ok.
As for the transmission, there are reports posted of people having problems at around 150,000 km. So I might be on the verge of having a transmission problem. But such problems are not so precisely timed. What if my vehicle had a transmission problem at around November 2006, and it has already been rebuilt, and as a result of that, it also already has the upgrade? If the reports are typical, then it is not that unlikely. In that case, further work right now would be a complete waste of money.
So it seems unlikely that I should take my Montana in to service for just this much work right now. I think I will wait till some other problem shows up, and if it looks like the motor needs to be pulled, then that might be a good time to ask to have the transmission inspected and upgraded. At least that is how I feel about it today. I could change my mind tomorrow.
Anyway, do not expect that I will have anything more to say on this matter, hopefully for a very long time. :-)
I bought 03 Montana and I have the same issue like yours.
I have taken to different Mr transmision and even to GM and was told
I have to replace the Tranny or rebuild it.
It's not a good feeling. I got it from an auction at the beginning of this
year and they say it might cost you around 2500 dollar.
I know what you are going through.
Good luck & wish me luck too.
Bye now.
the forum. I will follow your advise and please send me any think , I mean
any Info about this Montana.
Thanks again.

Anyone experience the same?
2 Problems - 1 : Driver side window power switch burns every time.
2: late kick - shift change- 2nd & 3rd Only..
When It passes 60km/h speed it runs well but when you stop & move
that's when the kick and shaking noise come.
I had a year and half & still driving because it's very expensive to change
the Tranny which a lot of people said is the issue.
Any help would be appreciated.
Thanks in advance.
