transmission up/down shift

[jack67]

I actually prefer to keep tow mode on all the time. It won't go beyond 7th. A little loss in fuel economy.

In "Tow Mode", mine will go into 8th but only on freeway straight stretches.

Interesting! I do long stretches of 70+ MPH and mine won't advance past 7th in tow mode. Mine is a pentastar w/ 3.21 gears.

I had a 5.7 in my last Ram. A 2013 Express quad cab. It had a 6 speed with 3.55’s. She would be pretty good with holding 6th even with a little incline. You just had to know how to drive her. Plus it had a HemiFever tune which I think did something to the line pressure which also seemed to help. Now my 2018 Big Horn 5.7 Quad Cab Big Horn with 3.21’s is another story. It has the 8 speed HP tranny and a Pedal Commander set at Sport +2, and yes, when approaching an incline regardless of how I try to ease the pedal ever so slightly, she will downshift to 7th, sometimes 6th depending on the grade. It’s normal and doesn’t bother me a bit. I love my Pedal Commander and love my 8 speed even more.

You will also experience a lot of faux shifting and shifting due to the MDS engagement disengagement. It is an outstanding transmission. For the 1st time this weekend I activated what I'll reference as hill descent mode, I was doing about 45 and applied ample brake pressure and felt it gear down as it will in cruise control to maintain descent down hill. I did not feel it holding enough speed back and reapplied the brakes, only to have it shifted down even another gear in order to maintain a speed I wanted but without cruise control.

This trucks tech with respect to the drive train continues to amaze. From tranny to brakes responding in such a way as to make axles act as though they are locked, i.e. all 4 wheels spin in snow from stop sign take off. To the fact that an open diff rear can lay out twin stretch marks from a stand still or the fact that it will break the tires loose in 1st, 2nd and 3rd with little effort.
Finally the biggest kick I get............15.063 seconds @ 93 mph weighing in at just under 6000 lbs on the track in a 1/4 mile and all bone stock.

My commute used to suck....... Now I know I can run that little ricer down and blow his doors off when he ****** me off so I just take solace in that fact and enjoy the ride.

My 2015 with 3.92s will downshift to 7th or 6th when going up a slight hill or speeding up slightly on a 70mph freeway. Sometimes it seems to hang in 7th and won't upshift back to 8th even after I completely let off. I usually have to coax it back into 8th using the Shift+ button on the steering wheel.

Has anyone had an issue with the 8 speed not holding in 8th gear. mine downshifts to 7th at the slightest incline then back up, kinda like a yoyo
Its a 2019 ram classic 5.7 with the 8 speed transmission.

I just got a 2019 Ram 1500 classic crew cab with 5.7, 3.21 gears and 8 speed. Mine does identical to what you described. Slightest incline on interstate and it drops back to 7th gear then back up to 8 quite often
