The problem is caused by electrical noise making the torque convertor go in and out of lock up. The dodge dealer has a computer flash for it. The fash only works about 30% of the time. This is a major problem to diag. Usually requires ground straps installed on pcm or pcm replacement could also be the altenator, wiring, or anything that runs to the pcm or tranny.

Have your tires checked, you probably have a shifted belt in one or more of the tires.

I would start looking for a vacuum leak. Check all the vacuum lines for cracks or breakage. Spray penetrating fluid on them until you hear the engine start to stumble then focus the spray on that area until you are able to pinpoint the location of the leak. Best of luck,my friend, Dana

98 Pontiac gtp skips 3rd gear to overdrive at 40 mph. It also dies and speedometer goes crazy starts right back up every time.Is it an electrical problem?


Try disconnecting the torque converter. If it is the torque converter this will keep it from skipping but you won't have overdrive

Sounds like overdrive or the torque converter is going out. The torque converter goes into lock up then the trans goes into overdrive.
Your owners manual should have a diagram of the engine compartment showing the dipstick. Is the check engine light on ?

Car is chugging a little bit at 45mph


The first thing that comes to my mind is "45 MPH"... and let me explain why.....

Your engine you said is running GREAT so a MPH is not going to effect the running of the Car but what happens @ 45 MPH you ask?

Your Torque Converter goes into Lock up.... If the Torque Converter is slipping in and out of lock up, you are going to have an irregular pulsating of the engine playing catch up.

you need to do this, try and drive the vehicle (you did not say what kind of vehicle it is), and drive it without the OVERDRIVE On...

So drive it and see if it is RPM RELATED. If there is no CHUG and you can go all the way to 55-60 without issue, Slow down below 45 and put the OD IN and accellerate and see what happens..

Is the Problem SPEED RELATED? Is it RPM Related?

If it does not happen with it OUT of OD, then what you probably have is a Torque Converter Failing...

I hope this helps

1995 oldsmobile- car makes a surging or jerking at 45 mph


That is the speed when it would normally shift into overdrive or the torque converter would go into lockup.
It is also when the engine would be working hard and a slight miss could be magnified.
You may want to have a transmission shop test drive it for their opinion.

Starts & run when put in gear shuts off, will restart 3.8eng will not move as though the trans is locked


There is a good chance that your torque converter is locked due to a torque converter lock-up solenoid malfunction. (pretty common) The torque converter lock-up solenoid is what locks the torque converter to put the transmission into overdrive. When they malfunction, it will cause the transmission to be stuck in overdrive at all times (this is not supposed to happen until the vehicle speed gets over 45 Mph). You must remove the side cover from your transmission to replace the torque converter lock-up solenoid.
Please also be advised that many of the solenoid malfunctions - especially on older, high mileage vehicles, are caused by dirt and debris in the transmission. This debris is usually caused by wear or breakage of internal parts (like clutches or bearings) in the transmission. I would recommend also pulling the lower pan and filter off to see what kind of debris is in the pan and evaluate whether this may be caused by a more serious problem.

In overdrive it feels like my torque converter isnt locking in. Any suggestions? It is an 02 silverado and normal rpm at 70 mph is 2000 and now its running at 2300


It is possible your lock up torque convertor has a bad connection or wire.
You should be getting a check engine light on in your dash.
You will need a OBD II reader plugged in to retrieve code.
Please let me know.

My 2002 trailblazer is making a noise when I go over 45 mph and appears to not be going in gear quickly at that speed


Check your transmission fluid level and/or have the fluid changed. If problem persist have a transmission professional at a dealership or transmission shop service it.

Speed sensor and overdrive


OVERDRIVE ENGAGEMENT IS TIED TO THE SPEED SENSOR SIGNAL, THE SYSTEM WILL NOT GO INTO OD UNTIL THE CAR REACHES A CERTAIN SPEED, IN MOST CASES AROUND 35-40 MPH, THE SPEED SENSOR SIGNAL TELLS THE ECU WHEN THE CORRECT SPEED HAS BEEN REACHED.
