My only real complaint with 7.3 is, in tow mode the minute you touch the brakes going down even a moderate slope, it downshifts too low for the speed I'm carrying, so Im going down slopes in 2nd gear screaming at 5000 rpm until I ease into the gas again. I find sometimes its easier to use manual and pick the gear I want. Towing about 8200 lbs with my 3.55 I get about 9-10 on rolling hills. 11 on flats at 65. Otherwise, I have few complaints about the truck. (except that gas cap lanyard.....argh!)
With my Ford I also do a lot of manual control of the gears. It seems to be too eager to down shift when the brakes are applied in tow haul mode and not eager enough to downshift when climbing hills. I would like to have the option of customizing some of the tow/haul settings, including different settings for different trailers. I don't see how that would be hard for Ford to do with everything already computerized.
I would think reprogramming is possible. Question is, will my dealer do it? I don't mind the downshift on a hills coming up. I can pedal it and get it into a lower gear on approach. But when it's screaming in 2nd and the road flattens out after descent, it takes forever to upshift again for no apparent reason. It sure pulls well, though!
Umm there’s zero chance that the dealer or OE is writing or installing custom trans tunes.
If you can’t handle the downshifting (I agree sometimes the downshift algorithms on newer trucks get a little carried away with the engine braking in some scenarios, but largely they are sooo much better than their predecessors it’s tough to pick nits….unless you’re a nit picker…lol.
I suppose you could try some of the tuner outfits but you never read about how they change the grade braking shift profiles. Worth a call though since that’s the only even remote option to “re-program” your trans
