With the introduction of the 10 speed Allison, you may not need 4:10 gears. My thought for a while has been to create an automatic that has a deep first gear (granny gear) that is activated only in Tow Mode. If this is the case, the you will not need 4:10, the deep low will get the load moving. This is just a guess, I have no information...unfortunately!Reports are it will have more than 30,000 Lbs towing also!!!! Looks like 4.10 gear ratio option will be returning finally to the HD Duramax lineup.
Last I looked TH mode does more than change shift points. It also raises line pressure so that the clutches don't get burned because of the heavy load- they have more clamping force to hold the load.10 speed might not even need TH the gears will be close enough together. I would rather have 410s and a taller OD to take some strain off the trans. 30k is a lot for a pickup

I agree, it is stupid that they moved it. I wish they would’ve left it under the passenger door. Now it’s going to be stuck up in the frame somewhere and make getting at stuff harder, and taking up space for things like compressors and tanks and inverter boxes.Sooooo, the DEF tank is no longer hanging below the passenger door? God awful design!
Where they will be sprayed with salt and slush all winter long?? That’s ok, I’d rather have them safe and tucked up between the frame rails where they stay dry.Well you can put your compressors and tanks under the passenger door if its that big of a deal. It needed to be moved.
Ok I am very interested in the 2020. One limit is the virtual cameras. Its limited to 32 feet trailer length. Now why a guaranteed over 30k trailering GVWR and limit visual to TAG trailers as it will not work with a GN. I have a 48 foot GN and I have the Rastra cams. I still would like to zoom up each side for things like bollards in gas stations by fuel pumps, curbs etc. Hope those "bigger mirrors" are at least 2 inches further outboard. How about the cell phone charger in the arm rest, did they make it a larger recess to enable phone cases and make a stronger charger power to charge thru cases? Did they add defrost mirrrors to the fold etc. No one has mentioned fuel milage yet? I like the new we colors too.
I was also wondering if they will fix the camera system so when your backing up, the pull foward you have to re-enter all your camera settings as well as cutting off the tailgate camera when towing as its no use esp on a GN. Did they establish greater clearance between the bed rails and the GN nose. Have they addressed the high possibiliy that trailers will have up to 6 tires on higher GVWR trailers will the truck tires have the same tire monitoring?
