Using Tow/Haul with Larger Tires

[Burla]

I'm not saying don't regear though, to be clear, I'd say you will like the truck a lot better if you regear, and you will want a tune with regear anyhow, so leave alfo alone and get a tuner.

Will a tuner enable / disable functions the same as Alpha or is it limited in it own abilities like alpha?

Also great videos. The caravan drum part had me in the second video. Haha typical chrysler.
Also made me want to rebuild my Trans. I only have 44k on it (probably off a bit due to tire size) but if feel like it may be early enough to catch problems before they start.

Update: I purchased Alpha OBD and upped my tire size in the system. Triggered my trailer brake and ABS to go nuts. (thought I destroyed my trucks BCM for a hot second, lol) Read back through the forum and found a section I had skipped over involving clearing ABS faults and the resetting to clear the codes.

Speedometer is now Correct.
MPG average says 12.3
Shifting is much better. (I can tell it wants some new gears still but its not gear hunting like it used to)

I started driving it without Tow / Haul and it feels great.

Thank you all for the input and help. This Forum kicks ass.

I've got 40,000 miles on my yukon 4.56 gear. Gears are the only thing in my opinion that will bring back that performance that lifts and 37's suck up.

If any of you fellas get the chance to ride in a lifted Ram 8 speed with 4.56 gears on 37's its going to open up a whole new world for you.

Truck is about to roll over 108,000 miles. She needs some maintenance but I've had other projects outside of Ram that I've been taking care of.

Marty's truck and mine are almost the same. only 2 difference's power train wise is I have factory 4.10's with LSD and 35's. pulls like crazy, mileage in this cold ass michigan weather is around 10.5 -11 mpg and really have not noticed any gear hunting since going to the 35's.

The only thing ive done differently is i dont use Tow / Haul anymore (unless im towing, lol) i just use the gear limiter. That way im not running extra PSI in my trans unnecessarily and it doesnt get into 6th where it loses all its power. Really gotta save up for those gears. But in the mean time it drives great.

Do you still have to use 10 year old junkyard parts up front to swap gears in a 4x4 ram?

6 speed trans here. I run around town in 4 and in 5 or 6 on the hwy. Tow haul is also a great way to disable the MDS. I think that is a lot of the struggle with these trucks. The MDS chokes it down.

It's too bad mds isn't an option
