So what's your opinion on the best/cheapest route to go for speedo only vs. speedo & shift points?
Maybe this is relevant to your interests.

Yep thanks --as soon as I decided to re-gear, I read that whole thread, & about a 100 more like that over the last few weeks from CTD guys trying to recal for lifts, gears, tires.
So far, I hadn't noted a big shift point difference, at least not enough for me to run out & buy something to correct the PCM/ECM gear ratio until I decide on which & what size new tires.

It's probably less of a concern for you. At some point I'm going to recalibrate but I have to prioritize projects right now.

So it seems AAM no longer makes the 4.88 R&P set at all. Your only two options are 4.88's from Yukon or Nitro gears. AAM still makes a 5.13 but only for the rear 11.5 axle. You will need aftermarket to go bigger up front on the 9.25. So the best from AAM you can really get is what we all have 4.10.

Google the part number and they're available. You use the gm/chevy front gear set with a ring gear spacer.

Ok, but that's not 4.88's it's 4.56. And still just the fronts.

I'm sorry, I remembered you saying in another thread you were going 5.13 and 40's so I thought you were looking for aam 5.13's which are available. Brain fart on my end, I know nothing about 4.88's. But if you're contemplating regearing for 37's or 40's you're much better off with the 5.13 ratio. I have trucks with both and the lower geared truck is better in every way. I'm not trolling you or anything, legit trying to help out.

Yeah,I know 5.13's are out there. I wanted to update this thread on the 4.88 because it seems like they were offering it. USMC and adeluca73 both mention buying AAM 4.88 gears. And now I can't find them. Anywhere. Seems like the current offerings are just aftermarket.
Also on the newer 2014+ trucks the only known programmer that will change gears you can buy now is the AEV ProCal. But it only goes up to 4.88's. So that is something to be aware of. If there is another programer out there, someone post up.
But the AEV is a much cheaper investment.

I've heard reprogramming for gears is unimportant, have you heard differently?

Tell me what I'm missing? What does it do? Apparently shift and mileage is controlled by the wheel sensor calibration. Several RAM techs have commented on CF that it doesn't do anything now that there are more wheel sensors. Older generations were not the case and needed gear ratio updates.

Does the Diablo tuner not have the ability to change gears on the new trucks like it did the old trucks?

I don't read CF, just ramforums and the FB group, so maybe I'm wrong. I was under the impression that you still needed to adjust the computer for the gearing. The comments were about it still being related to the transmission and that the patterns aren't just tire size, but gear specific. ¯\_(ツ)_/¯ But if the shift is based on wheel sensor, and that seems the case for tire size why then even offer gear programming if it doesn't matter?
Has to be a reason. I just don't know it. But if you're saying dozens of techs told you that then ¯\_(ツ)_/¯

Sometimes it's hard to tell the difference between fake and real snake oil.

Looks to me like they're just intercepting the pulse counter and changing the calculated pulse count to compensate for the difference in gearing. What's options setting?

Setting both the gears and tire size will give the computer the final drive ratio...

The truck already has that information based on RPM, transmission gear selection, wheel speed, and tire calibration. The gear ratio is redundant.

Reloaderguy is right. Resetting for gear ratio is pointless. Tire size adjustment does exactly the same thing. Re interprets the wheel speed sensor. Transmissions are programmed on wheel speed and rpm. Not gear ratio. It doesn't care what the gear ratio is. If it wants to know it can take wheel speed/rpm/trans gear and call it a day. This is another snake oil aev mumbojumbo

It all depends on which inputs the coder used when they set up maps for shifting and other controlled features. Sure there's lots of redundant sensors in modern vehicles... and there are different ways to calculate the same values - based on these different sensors.
If you have the option to set gear ratio - there's no sensible reason not to do it. Chances are, there is something in the controller logic that will use it.

If I'm not mistaken it is a holdover setting from older generation trucks that had a single rear wheel speed sensor mounted to the axle center. The newest (best) generation trucks have two rear wheel speed sensors on the ends of the axle. Again, the older gen needed the axle ratio because it was measuring input speed into the axle instead of output wheel speed.
Again, this is how I understand it and breakdowns for new trucks seem to support it.
