I just bought a new TT that weighs 6900 pounds dry weight. I have a 2013 f 150 super crew 4 x 4 145 wb. I put 33 inch tires on the truck with a leveling kit. I just pulled it from Texas to Louisiana. It's about a 420 mile trip one way. I noticed that I stayed in 4th gear a lot. It had plenty of power and pulled it easily. Even in 5th gear. But when I pressed the gas pedal to increase speed, it shifted back to 4th. Is this normal? Also...I have 3.55 gears
Thanks

Did you put it in tow mode? There's a button on the shift lever your supposed to press when towing.

Programmer with a custom tune will make a world of difference, especially when towing.

My 2013 5.0 does the same. Likes to stay in 4 th gear on the highway in tow/hail mode. Specially any wind or small hills,

you must have a 5.0 to have it need to shift down so much. Just lock out top gear and keep it in drive. Use tow haul button if you have to to keep from shifting so much....

Push tow mode and let ford do the rest!!

Thanks to all of you.

I was in tow mode. But wondering, if I go with the programmer, will it void and warranty?

Only if the dealer can prove the programmer caused a failure. www.stage3motorsports.com sells a tuner with custom tunes and an optional power train warranty in the event something failed and Ford denies the claim.

For performance tuning 5 star isn't very good. But their tow tune is pretty good.... Good shift logic too.
