2013 JKU automatic doesn't seem to have overdrive when on the highway

[Jay]

It does not seem to have overdrive when on the highway. Goes through the gears but never reaches overdrive. Rpm stay between 3-4k. Any suggestions?

Do you have the stock tires on?

So did you recalibrate your speedometer after the gear change and the tires?

 

[Jay]

Correct. I contacted the calibration tool company and they recent updated files that did nothing to help. Was wondering if changing the tire size or gear settings would help? Maybe 37 or 4.88?

Verify what your speedometer reads with GPS. If your speedometer is off it will mess with the transmissions shifting.

100% do this. I had the same issue when I got my 37's. I had used JScan though. I used the physical diameter of my tire to get the correct speed and shift points and not just 37".
