OK is around 2000 rpm cruising at 60mph (slightly more uphill) You should be at about 1700 going slower in high gear around town.
What you don't want to see is a "flair" when shifting, or rpm above 2500 at cruising speed except uphill. There are many things that influence rpm while driving...road conditions, uphill, downhill, tire size etc. but these numbers are a good "ballpark" reference. Your own experience with your car is the best baseline. If rpm is different than what you have gotten used to as "normal" you should have it checked out.

2002 Pontiac Montana trans problem


no I don't think so , it is only the torque converter clutch engaging and disengaging due to engine load. if you want to test this. go on steady speed over 50 mph no gas pedal movement. touch lightly the brake pedal but not braking and release . during this see the rpm drop down and raise

hope it helps

2002 rpm goes up to 2,000 rpm when i start it and around 40 mph it feels like it slips and goes up to 3,000 and stays goes up to 4500 rpm at 70 mph burning alot of gas and my engine just started rocking...


Sounds like the clutch, if a standard trans, needs to the be replaced. If it's an automatic, you need to take it in for diagnosis. Your trans. might be going bad, slipping, may just be low on fluid, if it is use some Lucas trans nonslpi and the proper tranny fluid to fill it to the proper level. Add the fluids and test drive bfore going to the shop, unless the tranny is fuul allready.

I have a 1999 Pontiac Sunfire. It seems to be high on the RPM's when i go faster in the car. Is there anything i can check to see what the problem is.


rpms do increase when you push the pedal to go faster....but then if it is an automatic tranny, it may be slipping thus rpms are fast but speed doesn't match rpms. luck to you

When I accelerate it does a fluctuation in gears...the rpm goes up and down...even when im driving at 40 mph it shifts then it hesitates at that speed..could it be the throttle sensor is dirty?


Is the "check engine" light on??? to isolate your problem have you tried MANUALLY shifting the trans (automatic) and still doing it?? check the fluid level and condition of the oil...sound more like the trans is slipping...the "TP" sensor will effect the engine and trans.But not cause over-reving......hope this helps...GL
