I drive a 2000 Sentra (has about 83,300 miles on it), and just recently I've noticed that when I get up around 65-70 mph, I'm at about 3000 RPM and it doesn't seem to ever drop. I was just wondering whether this was normal or not. I seem to remember I could go 70-80ish and it would always drop back down to at least 2,500 RPM but I guess I could be wrong; I don't do a lot of highway driving.

I checked the transmission fluid and it was a little bit low so I added some, but after driving around for a few minutes and then hitting the highway I didn't see any improvement.

Anyway, I just wanted to know, is this normal, or should it be checked out? Thanks!

edit: I just wanted to add, I have no problem going from 1st to 2nd gear, etc. It's just when I get above 60 mph.

The A/T in your car is a 4 speed with 4th gear being overdrive. It should have shifted 3 times to go into 4th by the time the car is doing 50 mph. Determine how many times it shifts, then report back to us.

I think it does shift 3 times. Once around 15 mph, once around 25 mph, and then it looks like it shifts a third time around 35 mph. When I'm going 50 mph the car is at about 1750 RPM, at 40 mph it's at 1000 RPM. Does this help at all? I don't really know much about this stuff.

From your description, it sounds like everything is operating correctly.
