Moved from a 2000 Navi to a 2013. Much more stable towing but not having control of gears from 4th to 6th is horrible. Does not seem to make a difference whether or not using Tow Haul Mode. Towing a 6000 lb trailer plus equipment so pretty well maxed out. When I come to a hill, speed drops and no matter how I work the accelerator, I do not get downshift through 5th, 4th, etc. All of a sudden I am down at 45 or 50 in a very low gear at 4500+ RPM. I know I could have kept it at 55+ if I could have made it to 5th or 4th before the severe downshift.

Any comments or suggestions? Any aftermarket solutions for manual control of gears?

something is weird....mine goes 6,5,4 etc. 2013 expedition (same drivetrain as the navi except has a two speed t-case). What happens if you set the cruise control? Does it not hold speed?

 

I have never noticed it downshift through the gears, goes down under 2000 and then up to 4000+ RPM even with cruise control set. No gear indicator so I never know what gear I am in. I have tried different methods with the accelerator and not much change. One time I did move from D to 3 so know that downshift was from 6 directly to 3 (there was no shift or change in RPM when I went to 3). The only time I know I am in 4th or 5th is when accelerating. I will mention to dealer the next time I am in and see if they can diagnose any issue. I wish I had manual control of all gears!

BTW, it maintains speed with cruise control but bogs way down (slows 5 or more mph), downshifts and then goes to extreme RPMs to get me back to speed. I am sure if I was able to manually shift to 5 when the speed dropped a little, that would have maintained speed so it would not have had to go to 4500+ RPMs to get back to speed and then start all over again.
