2000 grand caravan won't go above 70 mph. high rpms

the 4.0L engine?
is this engine cold or hot.
why is 2000 rpm wrong for 60mph., (depends on engine and axle size and what gear you were in , then)

the idle speed for hot is too high
did you scan the PCM yet?
if hot , idle is high, is the thermostat holding water temp 180f or above. ? if not that is the problem.

Caravans can have issues with the sodering on the guage cluster boards. If you can't solder you may need to replace that part.

Standard Shift? Clutch is Slipping

Automatic? It is coming out of gear or slipping

If it is an automatic-- you most likely will end
up having to rebuild it,if it is original since built for yr 2000

I'd have to check your suspension. You think the tires are ok? Did you try rotating the tires to see if it made any difference?

yep,that right,3500 = 70 mph.in5th gear. small engine/high revs.

You need to back off the transmission kickdown cable. It is located just beside your throttle cable near the air intake duct. You may have to remove the black plastic cover to gain access. Just back of the adjusting nuts about one quarter inch at a time until it operates correctly and lock them down at that point. Thank you, Dana

get the codes on trany OBD2. what does the over drive button is saying on the dash Vitally

i believe you might have a tranmission issue. you should get the check engine light check at your local autozone for free

It sounds like the last gear in your transmission may not be engaging. Caravans are actually famous for tranny problems. Furthermore, be sure to check your transmission fluid while your vehicle is idling. That ensures accuracy. But you may have to get someone to physically look at it to ensure your problem gets solved. Kind of risky diagnosing something so big through typing.
