It's actually more efficient. As a matter of fact, you can see it in action on the fuel economy display in the cluster. It's the same with the manual; fuel economy is observably better when you downshift to a gear appropriate for your speed of travel, even when coasting. The eight-speed auto does it for you.
My rams work the same as this JL, neither one of them is more aggressive than than the other. There is a allot of posts about this same thing in the ram forums, when ever someone gets a new 8 speed.
Nothing on Google about a recall yesterday. There was a older recall on the 6 speed auto 2500. The 8 speed is a hell of a transmission. Allot of the problems with the 8 speed and dial shifter is user error. All the JK guys would probably loose there mind ,if they would of put a dial shifter in JL .LOL
I mean, this is obvious and we all know it, and it doesn't really touch on the topic at hand. The JL aggressively comes to a slow down when you're off the gas and coming to a light. This doesn't feel like no gas is burning, it feels like it's actively using regenerative brakes or something else from a hybrid. It's far more aggressive than the 50+ "It's been that way since the early 90s" cars I've driven prior to the JL. The difference in your analogy is that if I attempt to coast without pushing the gas the Jeep will feel like it's literally braking for me at the same time.
I have yet to see this aggressive engine braking in mine. Is it something that's specific to the Rubicon? Because if I go downhill and I need to engine brake, I have to go into manual mode to make it downshift (usually from 8th to 5th) for me to feel anything. Or maybe I got too used to my old Ram's excellent engine braking that the v6 doesn't feel like it brakes quite as much.
I'm not really sure, it's my first Wrangler and I've only driven the Rubi JL so far. It's super aggressive. Best way to explain it is if I plan to coast up to a stop light where cars are sitting I usually let off the gas and roll up 5-10 car lengths, except with this I'll hit about 1-2 car lengths and almost come to a complete stop with 8 car lengths to go. I have to push the gas again. It feels exactly like regenerative brakes in the Hybrids I've driven where they're basically pulling you backwards.
Maybe I should sneak a test drive with a Rubicon to see. lol
I guess maybe that's what I'm not understanding. You say your Ram is good on engine braking, so I'm guessing you see it as a positive. Is this not more wear on the transmission? For instance in all of my cars (DCts/manuals) I go out of my way to wear out the brakes instead of the clutch/transmission because it's way cheaper to replace brakes than any driveline parts, especially $3500 clutches on a DCT.
Engine braking does no more wear on your driveline than accelerating and cruising and is a normal function. Aggressively using your brakes will wear those down faster than any downhill engine breaking will do to your transmission. All it is is using the compression stroke to provide some resistance to unwanted acceleration when you're going down hill. Now that being said if you downshift too far you'll damage your engine if it revs too high. Modern automatics won't allow this but in a manual I don't think there's anything to stop you from doing a 6th to 2nd downshift and that will ruin your day pretty quickly.
Same here in my Sahara. I actually prefer engine breaking and I am shifting into manual mode to down shift when coming to a stop.
Well hell, thanks. Stupid me always assumed "engine braking" was just a misnomer for using the transmission as your brake but that explains it.
Ah its no worries. Coming from a hybrid your experience is going to be different, and I've only driven one a few times.
