rpm at highway speeds

[Ldub]

Are you in "power mode" or "normal mode" with regard to the trans control button on the ctr console?

If in "power", try "normal", the TC will lock up at a lower rpm.

3000 at 70 mph is too much. To see if you're getting into overdrive just shift down to third gear when cruising at 60 mph. If the rpm's jump high you were in overdrive. Shift back to drive and the rpm's should drop back to where they were. If you shift to third gear and nothing at all happens then you were in third gear already and you're not getting up into overdrive and something is wrong.

I decided about a year ago to always run in "power mode" and haven't looked back. You get quicker shifting in power mode and my gas mileage has maintained the same 14-17 MPG. When you drive at highway speed the transmission will still shift to OD & lower the RPMs to normal until you start accelerating it will downshift to third gear pretty quickly.

When I was in "normal mode," The transmission always felt like it was trying to shift up constantly & too early where I would lose the power ban going up hills. It may just be my VX, Colorado altitude or larger wheels but my VX transmission feels much smoother on power mode.
