Remapping Transmission on Triton V10?

[lordnorth]

I was wondering if anyone has any suggestions on remapping the shifting on a Class A with the Triton V10. Just purchased a used coach and it just will NOT stay in high gear for ANY kind of an upgrade with the cruise control on. Any slight rise and it downshifts, kicks the RPM's to about 4000 and screams up the hill.

If the cruise control is NOT on, it doesn't downshift nearly as aggressively.

Additionally, I would like to bring the shift points of each gear down slightly as I am more concerned with fuel mileage than in being able to race up a mountain without losing any speed.

I have heard that it can be done... I just don't know what my options are to doing it.

Thanks!
Chris

I can tell you that tbe Ford Cruise Control is "lazy" when it comes to maintaining speed. With my X with the V-10, when the cruise is set and i get to a hill the truck will wait to increase speed untill it has dropped a few mph. By then it is too much and the engine then has to rev to try and get back to speed! The only thing i hate about the X right now!

And i would seriously look into the 5star programmer! It changes the shift strategy so it will hold gears longer. And when it does shift it will keep it in the power band longer!
Some of the best money i spent on the X!

Nope he doesn't. He has the Torqueshift 5sp -5R110W. It was introduced in 2003 behind the 6.0L PSD. The 4R100 was behind the 7.3L PSD.

Tow/Haul will not affect the aggressive behavior of the engine management system to maintain speed while using CC. The tranny will drop gear(s) and rev like heck to maintain the set speed.

You either live with it, turn it off on hills, or put a programmer on it to change the shift program. It does not matter if it's in T/H or not.

Sorry, I actually missed his later post where he identified the year model of his chassis. He didn't state that information in his first post and I just assumed (really don't know why) he was talking about an older unit.

As for the 4R100, it replaced Ford's E40D. It was actually introduced in 1999 in many of Ford's gas truck applications (including their F53 motorhome chassis). The 4R100 also was used with Ford's 7.3 liter Power Stroke diesel in 1999 - 2003.

Thanks for catching my error...

Safe travels.

I guess I should have clarified... I have a 2011 that has the 6.8L V-10. So I guess this means that I have the "latest and greatest" already.

I get what many of your are saying, about letting it rev high and about using the cruise. I admit.. I drive big trucks and max my RPM's at 1500, so EVERYTHING sounds like it is over-revving. But at the same time... I don't understand why, with the cruise off, it will maintain a given speed up a rise without downshifting, but with the cruise on, as soon as there is any slight upgrade (not talking mountains here...) it instantly downshifts.

The previous owner suggested, and it seems to be the best option currently, that as soon as you see a slight rise, you kick off the cruise, get up the hill, cruise back on. Repeat as necessary. It works, but it does make for fairly tiring driving. (Again, coming from someone who is used to spending a lot of time in the drivers seat. I just don't feel that driving a Motorhome should be that much more tiring than driving an dual axle sleeper with a 53' trailer, but it is...)

Again, thanks for the suggestions.. I did look into the 5 star tuning as someone mentioned (see the third post in this thread), and I did look at the Banks system (looks like that is for the older Fords).

Anyone else, please feel free to chime in.

Thanks!

Use the "TOW HAUL" mode and it will change the shift points of the trans.

Chris,

I believe that you have the Ford 4R100 transmission. That being said, while I personally have not used the product found at the link below, I do have two friends that have used it and are very happy with their results. Banks normally makes a good product.

The article at the link is also good reading.

Safe travels.

5-Star

Installed on my 2011 and love it. Fixed the constant 5k scream when the overpass was still 1 mile away (ok, not really 1 mile away but it seemed like it). I still take it out of CC for large hills and mountains as I can control it better but overall I'm a huge fan.

My older (2001), when on cruise control and taking a hill, the speed drops around 20mph from the "set" speed before the cruise control disengages. Different tranny than yours, (OP) of course....
The V-10 likes RPM so 4000 isn't bad, and of course, all these motors/trannys have rev limiters on them so you simply can't blow the motors up due to excessive RPMs. And...when the thermostatic fan kicks in, that makes for a hellofanoise, but don't let that fool you.
As far as fuel "economy"? Laugh. 7.3-7.5 on a gasser is all you're gonna get. Diesels do better...but diesel fuel is 50 cents+ more a gallon...so maybe it all equals out.
Stil not satisfied? Call Ford Motorhome and ask them about a possible reprogamming available for the cruise control "problem." Y'never know.
Enjoy your motorhome.

The Torqueshift 5sp auto is with the cruise control on "AGGRESSIVE" to say the least. My 6.0L PSD does the exact same thing. Hit a hill with it on and the tranny might drop 2 gears to race to the top - goes like a bat out of hell. 1st time it did scared the******out of me!

All I can say is it is designed to do this and if you don't want it doing it either get a programmer to change the shift pattern or kick off the CC on hills, that what I do and it'll save you some fuel.

I used5 star tuning on my 2011 6.8L V-10 and was pleased with the results. If you can wait a month, I can sell it to you for half the price you'd get it new.

Just PM me.

X2 on Banks Trans command 115,000 miles and counting. No more down shifts on overpasses

I have a 99 Coachman with the V10.I bought it when it was one year old.I hated the way the trans shifted.Slow to upshift,slow to downshift,and sluggish shifts.I installed a Banks Trans Command.Best improvement I,ve made to the MH.Not sure if it helped my gas mileage but I love the way the trans shifts.

[chuckftboy]

I often wonder why 4000 rpm bothers most people? Maybe I'm just more used to it riding motorcycles and driving boats but it just feels like power. If the motor doesn't mind it, then I don't either.

I agree with othertonka 100%,
