So update. I called the dealership, they said 4.10's were impossible because they are not supported... Pfff WTF happened to competency within your field? Anyway I called a different dealership and he was aware they exist, but it would void the entire warranty. Now I am torn.

On a positive note, it does settle me toward getting a full tune. I am contacting a local shop (Texas Drivetrain and Performance) to see where everything sits price wise and mindset wise. I am leaning toward saying screw it, and screw the warranty.

He's wrong. They all say that, but they're wrong. I would just do what you want and if the engine blows up, reload the factory tune and take it in. You can fight them if they try to void engine warranty for changing the rear gear ratio.

Check this out. The second guy, who acknowledged they do exist, said that 4.10's would have the engine and transmission "working harder". I argued the point quickly that it would work less, but only turn more RPM's... I was going to have the dealership do it, but it seems like it would be high dollar (if they would do it), for the same modification, and warranty loss. I hear you on all of that, problem is I am due to Germany next and wanted to do all of this prior to. This would make it difficult to reload the factory tune... Anyone with some ideas so I can have cake and eat it too?

GO to a site with a RPM calculator ........ make sure you know your trans ratio in OD or what ever gear you use ( in a 6spd I plug in 5th & 6th as I tow in 5th) and tire height ........then play with the calculator to see what the cruise rpm at the speeds you like to drive at ........ what rpm do you cruise at now ?

if you have a 5.3 I would gear for 1800-2000rpm at the speed you like to cruise at .....difference at @2k between 3.73 to 4.10 is approx 200-300rpm

Look for yet another, more competent dealer. Warranties can only legally be voided if the mod is proven to have been the cause of the damage. The dealer CAN however refuse to work on a vehicle due to mod. So if they want to take your money to do other work, but refuse to work on a warranty issue, find a new place.

Having just completed the TBSS with 6L90, I'm sold. All the bench mechanics online claiming 4.10's are too much are clowns. This truck ROCKS now. You'd think I had a head cam package...shifts are quick gear drop and I'm halfway around the slower traffic.

BTW, do NOT reflash your ECM, get another ECM and mod that one. GM can track mods done to the ECM for something like 100 start or flash cycles.

How hard is it to get to the new ECM. Also what years will swap over (so I can pick one up).

If you have a 2010 with a 6spd you have a ECM & a TCM so not as simple as buying another ecm ............do some research
IMO the E38 ecm in 2010 silverados do not have that function that tracks flash changes .........some controversy on this topic so do your homework ..yes some GM ecm's do have that function but based on what I know not the 2010 e38 ........... this has been discussed alot on other boards ......check with some experienced tuners

From what I have seen on here with people using the same equipment the dealers use, they can only check the flash history on the new global vehicles (2010+ Camaro, maybe new Regal, etc) and not on the 2011 and older GMT900s. All they can do with the GMT900 trucks is check your current calibration.
