After towing a loaded 12X6 U-haul coast to coast with a 2006 Screw 5.4l 3.55LS with 285/70/17's, I decided to give it some help for the way back. I am swapping gears for Yukon 4.11's this week. I have an order in to Mike Troyer for an AF1 3.5" CAI, Roush SIDO exhaust, and an XCAL3 tuned. I have been looking at transmission and differential covers. I also need something to monitor temps. I still have the stock 30" tires. I'll probably mount those the next time I pull a long trip if it's not to small a diameter for the 4.11's. Any other suggestions?

 

Leave the tire size alone. Otherwise you are reversing putting in the lower gears. I would make sure you have LT tires rather than P-series tires.

 

Thanks. I went to the higher ratio gear to compensate for the larger 33's. I thought dropping back down to 30's when I tow long distances would help. But then that would probably mess with the tune set up based on 33's and 4.11 gears.

 

Sorry, I meant it would be better with the 30" tires. You would actually have a higher tow rating. But since you towed with the 3.55 and the 33" tires, you should be fine with them and the 4.10. I missed that you had towed with the 33".

 

if you want something to monitor temps take a look at scan gauge II, i just got one and they are pretty awesome. tells you every thing, and is pretty accurate. price is very reasonable !!!

mag hytec tranny pans and diff covers

 

another thing to add would be a good tranny cooler.
I pulled a 8x18 tandem cargo trailer from Wa. state to Fl. trailer weight+cargo= 10,600 lbs.
Oh yeah, and did i mention the mighty 4.6/4R70W done that job for me!
mods for the tow:
-4.10:1 gears(yukon)
-detroit truetrac
-transgo shift kit
-11"x 13" aux tranny cooler-stacked plate design
-New dual core radiator
-Heavy duty fan clutch
-gibson exhaust
-Prodigy brake controller
-Diablo predator
-10,000 lb weight distributing hitch
-hellwig ad a leafs the big ones(2500lb?)
-goofy mirrors that attatched to mine.
Took me 6-7?days, kept speeds about 60 mph, except for those Idaho mountain passes were killer, up around 8000' elevation. then i went about 25 mph.
one thing i wish i had were electric fans, which would definetely help out.

 

Check out http://www.dashhawk.com/ as well as scanguage. Dashhawk has more features/functionality but scanguage is cheaper.

 

look at the info the dashhawk offers versus the scanguage=the scangauge info is more useful

 

I have a Scan Gauge II, and I don't think it will provide tranny temp. Intake air and water temp, but I haven't seen tranny before.

 

interesting- my 04 van with the scan gauge 2 displays tranny temp-check out their website-it's a ford feature-phil

 

Not totally sure how you define useful nor how the OP would define it either. You would do good to look into both further before making statements like that though. I looked at the scangauge before I got the dashhawk and since at that time the scangauge didn't have tranny temps (they do now) it wasn't in the running.

Facts are that the dashhawk offers many of the same info plus alot more and is a lot more flexible in its display of that info. For towing I've found the torque converter slippage counters invaluable as a proactive indicator of which way my tranny temps will be heading. The only thing that the dashhawk doesn't have that the scangauge does are Trip fuel economy and DTE which I don't need, but I do find the instant fuel economy very useful when towing. I can adjust pedal position based off of that and improve overall fuel economy. They are working on trip fuel economy (as well as instant hp and instant tq which I can't wait to play with) and tend to release new features or updates every 3 months or so. Either way they are both good tools, just depends on what you want and need. I would still recommend to the OP to check out both. I don't care which he gets
