‘20 159 HT window van NH Seacoast
Try moving it more than once to select the gear you want (sorta like double clutching)
my owners manual pages 191 to 199 explains the use of the shift lever.I have a 2017 gas 3500. It's been converted to a camper and is near the GVWR. My question has to do with how to operate the transmission. I can't figure out how to get the transmission to operate in a lower gear when I need it to. When driving up steep hills sometimes the transmission remains in a low enough gear to get to the top without struggling (high RPM with plenty of reserve power). Other times the transmission shifts to a higher gear as I climb the hill, and I end up with the accelerator floor boarded, low RPM, and the van barely makes it.
As you all know, the gas transmission shifter can be moved to the right from the Drive position, and then it's possible to move it up or down. Based on other vehicles I've owned, presumably this should allow the driver to manually select a gear, or at least stop the transmission from up shifting. But apparently I'm not doing it right, because it doesn't seem to make a difference. My owner's manual says nothing about how the gas shifter works. (It has plenty to say about the diesel manual shifter, but ignores the gas version.) Could someone please explain the operation of this gas transmission, especially how to down shift, or stop up shifts, if possible?
Well, on page 191 in my owner's manual it explains how to check the power steering fluid and set the parking brake. Obviously they gave me the wrong manual. (Maybe they have a different one for diesels and I got that by mistake.) So thanks for mentioning the page number in your comment, because it sent me to the Internet to download a PDF of the correct manual, and sure enough, there's a description of the "Electronic Range Selector" for gas engines in that version.my owners manual pages 191 to 199 explains the use of the shift lever.
move it to the left then push it forward to down shift and pull it back to up shift.
it actually says that the gear you select is the top gear the transmission will select. It may downshift on it's own to a lower gear if necessary.
Thanks for the tip. I'll give that a try.Yep, it shouldn't shift any higher than the gear you select. Once you get that fixed, try tow/haul. Our conversion is fairly close to GVW and I find it noticeably improves shift timing on hills. It also works in combination with ERS if you want to downshift further. I often do that going down long hills.
