MPG and range

Did you notice it takes a few seconds to register the gear change? I can feel shifts and it is a bit before it shows on the screen. Also some shifts you cant feel at all

FWIW, not the case on our FCA Durango (2015 with 8.4 and 8 speed). It's quick.

So far, I haven't noticed, but I just drove it around the block to check I out. When I do some real driving, I will report back.

I feel the shift and then it's about 1 second before the display updates. I know it before it shows but it's not beyond about 1 second, two tops. I can only count about 1 Mississippi before it shows.
I'm pretty tuned to how the thing feels and detect most shifts anyway but with our hills and wind, it sometimes is shifting a lot back and forth and I lose track of the gear it's in. (winds tomorrow to be about 45 mph)

Of course the easiest/quickest way to see what gear you are in is by using the manual shifting option! Which I am surprised there are very few threads/posts on out there or here

I've not used it yet because in most cases the computer is actually at least as good if not better than me at keeping it in a gear that matches the power and torque for the situation.
My other cars - my Javelins for example (one I sold recently) both automatics and yet I shifted those manually most of the time. No computer, old-school, in the later one a throttle valve determining load against the governor road speed and in the older one matching governor/road speed pressure against manifold vacuum to determine load vs. speed - so I did a lot of manual shifting.
My other car - a stick..... T5 and my WJ I am always popping it out of OD and back again due to our hills and steel inclines here. I can actually get a touch better MPG with it that way. Otherwise when it finally decides it's loading the engine up or lugging it downshifts WHAM and the engine winds right up - so I pre-empt that with an OD off.

I find the manual shift on the JT to be backwards - I mean pull back to UPshift? Give me a break. PRND2L - you move it FORWARD to upshift in older vehicles.
When racing with my 73 automatic, I start out in low - shifter all the way back, grab that T-handle and shove it forward for 2nd, forward again for high. I don't pull back. And high or 5th in my stick - far forward to the right.
Maybe Jeep was thinking the reverse valve bodies put in the older automatics for pure race use?
But to me UP-shifting is FORWARD, not back. If I wanted to downshift I'd yank the shifter BACK.
That may be one reason I don't manual shift - they got it backward.

I manually downshift my vehicles often to save the brakes. Once I'm stopped, shift back to D.

I do that too except with this because I've felt that it has learned to downshift when I use the brakes a certain way. I've noticed if I wanted to slow more than slowly or stop - it seems to drag me back and I've noticed when I relax the brakes the truck is STILL slowing down - like it sensed my wanting to slow or stop.
My brakes have always gone over 100,000 miles so I'm not concerned about these heavy brakes. This thing stops like no other vehicle I've ever owned. The best brakes I've had on anything.

Agree on the brakes. Speaking of gear shifting, I noticed that mine stays in 4th-5th gear even when decelerating to as low as 15mph, it really doesn't go to first gear until after I have stopped. It will spend its time at or above 45mph in 8th gear usually. Gears in between shift really quickly and in quick succession.

I was always told its easier to change brakes than change a clutch, unless you're rev-matching your downshifts.

I don't think I am following what you are intending to convey. You mean shifting up/down as the RPMs go up/down?

He's talking about a stick I bet (we're talking automatics) - but then I've never had to change a clutch out before 80-100K either. If you don't slip it, it's no worse than upshifting in my experience. (I never had an automatic until later years, my AMX, Javelin, first trucks, all sticks)
I also don't downshift a stick into 2nd gear when running 45 mph either. I shift down through the gears according to road speed.
I always downshift my SX4. First clutch went 160,000 miles.

I've noted that, too - it won't hit the lower gears until you stop or nearly stop for sure.

Clutches can last a lot longer than people think. I am the original owner of a 2001 manual BMW e46 M3 Convertible and it has 226,000 miles with the original clutch -- and when it was newer, I used to really get on it, so, the clutch was not always babied. I do practice rev. matching when downshifting.. The clutch is harder to push now, but, it still works perfect. I keep thinking I should change it, but, what the heck, it still works perfect... lol.

PS. I hope I can get the Gladiator Clutch to last that long. I am crossing my fingers.

You are right - they can last a very long time with even moderate care - I changed the clutch in my SX4 only because I changed engines (swapped out the 258 for a 94 ZJ 4.0) and rebuilt the T5 transmission, replaced the bronze pilot bushing with a sealed ball bearing, put in a NOS transfer case, etc. and didn't want to hassle with taking that 4x4 apart again - what a pain. Since it was apart at 160,000 miles, I put a clutch disk, pressure plate and more in there. Do it right, do it once.

yeah I thought you guys were downshifting a manual transmission to engine brake, to save the brakes.

I've known people that do this with just slowly letting the clutch out, so it wears the clutch then engine brakes.

if you rev-match your downshift in a manual it doesn't beat on the clutch.

Didn't realize you meant automatics.
