3,100 rpm at 70 mph. Overdrive works. What do i need to check?

2011 dclb 4.0 auto trd sport. Have 32x10.5x17 on it but did the same thing with the stocks on it. Overdrive seems to work so i dont know what to look for? Recent transmission flush from toyota dealership. Also really really slow on the power. My buddy has the exact same setup with the 4.0 and he runs around 2k at the same speed

 

Sounds like a whole lot of torque converter slippage

 

Were you in 4 or D?

 

Power response is normal. And D

 

Something doesn’t add up with your truck.
It’s right for your buddies.

Here is a chart with your tire size, gear ratio, and 3.73 gear.

 

Have you manually gone thru all gears to make sure it is going into 5th? Also check your trans fluid level.

 

How does the speedo feel?

sounds 4th gear to me as well, there really should be a check engine light on if that’s the case.
