Transmission gearin/RPMs in the Automatic?

[Degnol]

I've had my FJ since Wednesday and I thought that the auto was an overdrive transmission? Yes?
At 70mph I am turning 2750 rpm. Now I'm wondering if the transmission is shifting into the overdrive gear? That seems high to me
Looked in my Owner's manual and cannot find the gearing specs for 5th gear.

EDIT: Using 3.72 for the differential, 2750rpm and 16" radius for the tires, that calculates to 70.4 mph, which leads me to believe the OD is not working.

I just found out why the D-4 gate is so wide. What a dumb****.

Just in case others need the information. This is for the AT transmission.

Gear--------Ratio
1st---------3.52
2nd---------2.04
3rd---------1.40
4th---------1.00
5th---------0.72
Reverse-----3.22

i was gonna suggest making suyre in was in D and not 4, but i felt like that might come off condescending, i know its a mistake i made the first week i had it. stupid gated shifters.

This information is in the Factory Service Manual.

I'll sell you my part-time transfer case from my AT that I removed with 8k miles on it. Then you can have a 6-speed with part-time 4WD. The other option is to install an Inchworm lefty transfer case.
