When I tried this the first time I really never noticed a change but when I do it now I can feel the downshifts are a bit tamer but still really noticeable.  What are you experiencing when turning off grade braking?  

When I first started using the button to turn off grade braking it did take care of the occasional clunk when downshifting for me. The shifts were a bit snappier when I PULLED THE SHIFTER DOWN UNDER D,  but I long since went the route of a tune for complete satisfaction. I really wasn't looking for more horse power from the tune, just wanted my trans to shift like I thought it should.

It does now.

So which Tune did you purchase and install?

I went with Black Bear custom tune. Justin sent 1st tunes and I asked him to crank it up a bit more. Second TCM tune was a keeper.

Can you still feel your downshifts after the tune when slowing down or not?  What I am feeling is a very firm bump with a 200 RPM rise at approx 40mph, 30mph, 20mph and almost stopped.

I no longer feel any downshift. For me it was only occasional before the tune: Less with grade braking disabled. Now it is gone altogether.

i love it in Manual 4-5, perfect for stop and go city driving. automatically disables the cylinder deactivation, and increases the clutch pressure so the trans runs very cool at 145 degrees. On the freeway i leave it in Drive, it's great for gas mileage , but there is too much clutch slip and the trans overheats and runs 190 degrees.

For those with a 2017 and the 6 speed...

 

How many miles did it take for your truck to shift better?  I am at 400 miles now, and it is very clunky on the downshift, worse than it was at 100 miles....

 

Anybody have any insight as to how long the learn mode takes?  I hope it gets better.

Does it do any damage to drive the truck in manual 4-5 constantly in city driving?

No

Same as a stick shift in 4th or 5th gear.

[No Tyme]

Well, almost the same as a stick. You don't have to downshift just set it in 4th or 5th and it prevents overdrive and the V4 mode. I believe it tightens up the shift pressure also.

Not a bit.  My 2013 1500 and my 2015 2500 spends the lion's share of its time in 4 or 5 manual mode.  Not necessarily because of the AFM thing with my 1500, and my 2500 doesn't have AFM.  Mine is more about the rolling hill rural area I frequently drive in.  Keeping it out of top gear and there is a lot less gear hunting going on and shifting on every little mole hill.  Saves a lot of wear on trans, actually does better on mpg, and trans temps stay quite a bit cooler. Only time I let it go into top gear is on the 4 lane highways.

The 6 speed on this 2017 is a clunky hunk of crap.  I only have 600 miles... but it better smooth out....

[JacobC1983]

Does anybody with a 2017 have a downshift clunk from 2 -> 1?  

 

I know the 2017 8 speeds had a software update, has anybody with a 6 speed had their TCM updated?

[Donstar]

Manual mode allows for more driver input but comparing it to a "stick" is  a stretch,  imo.  Some characteristics (including the name) may mimic a manual transmission.

I feel my 2017 six speed has actually gotten clunkier over time. At 8500 miles, I'm not real happy with highway shifting. When I hammer the pedal to pass, it kind of hunts and hesitates.
