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

Is it normal for my 91 miata reads 3900 rpms going 70mph?


It is pretty close, but doing the math....
3900 rpms 5th gear .814 diff gear 4.3 tire rpm = 1114
stock 91 tire size is 185/60-14 circumference = 71.31 inches inches/min=79457 mi/min=1.254 mi/hr=75.23
Completely stock, 3900 rpm gives you 75 mph. not the 70 you were claiming, but you could have smaller then stock tires (one inch less of diameter gives you 72 mph at 3900).
Hope this helps, Lars

My 2000 pontiac sunfire with a 2.4 motor and a 5 speed manual tranny will go in to all gears however if trying to drive the only gears you can move the car in is 5th and reverse , all other gears act as...


Check the cables and shift linkages.If they are all good then it could be time to replace the trans.unless you know someone that is a good trans mechanic.You could price out a used one from the salvage yard.Hope this helps.Good luck.

I just wanted to know the optimal shifting points to do 70mph comfortably. Should the car be at 2500-3000 rpm in 5th gear at 60-65 mph? I typically shift at or around 3k rpm in every gear, and the car...


How many gears does your car have? One of my cars has to do a little over 3000rpm to maintain 70-75 in 5th gear. My other car has to do about 3000rpm to maintain 65-70 in 5th gear.

It all depends on the number of gears your car has and the gearing ratio. The second car I have is geared more optimally for city driving and gets better fuel economy going slower than fast highway speeds.

Having driven several rental cars too I would say anywhere between 2500 to 3000 is reasonable for the average car. If you are driving a vehicle like say a porsche, bmw or audi they may have more gears and may be at a lower rpm at 70mph than your car.

Oscillating vibration around 60-70 mph in 6th gear


sounds like a cv joint to me. That is what usually occurs when one is showing wear. C.V joints usually wear out between 80,000 and 120,000 k.m.

RPM's


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.

4000 rpm at 70 miles per hour


You should have another gear "5th" at 70mph your tacho should read about 2500 rpm.
Make sure you don't need to depress something or push the gear stick against a spring to select 5th.
Is there a gear layout on top of the gearstick knob, do you have 5th gear on there?
The highest gear ratio is a little over 1 to 1 so at 70 mph you would expect 3500 rpm, but, it is a little over 1 to 1 so it will be closer to 2500rpm.
