8 speed transmission review

I want to find out what others think of the new 8 speed. I have about 2200 miles on my 5.7 8 speed and I think while the transmission is smooth for the most part it can be improved. The through gear operation going up through the gears is good 1st to 2nd could be a little better but not bad. The area where it needs improvement is when slowing down at lower speed. I think a couple of the shifts going down are too soon and I think when driving at low speed like through a parking lot it feels and sounds like a manual transmission sometimes. So I though I would see how others felt about it? I would expect at some point they will have a flash to improve this.

Re: 8 speed transmission review

We have 1300 miles on ours and no problems with it so far although I'm still not comfortable with the electronic shifter. I don't notice anything at low speeds, is it like a lag between shifts?

Re: 8 speed transmission review

I find the 8 sp in my V6 sometimes slow down-shifting into the lower gears while coming to a stop...and up-shifting accerating from a stop.

This all while in "Eco" mode.

Re: 8 speed transmission review

Overall I am happy with the transmission. At very low speeds "ECO" mode interferes with it. It seems to force a shift into 4th too soon.

I still think the shifter is a mistake. This is the only car I have ever driven where I have to always double check to see if I am in park. I don't understand why Chrysler couldn't keep a conventional interface even if the lever was connected to switches.

I know many folks have said they are used to it. My question is what advantage, to the driver, did this change accomplish?

Re: 8 speed transmission review

Is there a mechanical linkage between transmission and the shifter? Maybe it was done for "packaging" reasons to compact things.

Welcome to the 21st century my friend!



No real advantages to the owner, but a cost advantage to the manufacturer (less parts to worry about). Expect to see more "fly by wire" systems in automobiles in the future...for instance the V6 models have electric assist for power steering as well (but retains it's redundant mechanical linkage as backup).

When it comes to the shifter, I've found it's easier to know what gear you've shifted into by adjusting my dash readout to display only the current gear selection...not the whole "PRND", and I've learned to just push the button on the gear selector, and push/pull & hold until I see the gear I want displayed on the dash readout.

Every time I turn around somebody is trying to drag me into the 21st century.

One of the first things I did was switch the display, and you are correct in that it does help. I just think it's a step backwards that after 40+ years of driving, I now have to look at the dash to shift an automatic transmission.

I don't mind the technology, but how hard would it have been to use that same lever and have 5 distinct detents?

Re: 8 speed transmission review

I actually like the new shifter and very rarely will I miss a shift. The detents feel just like a traditional PRND pattern...

Looking at the center display to see what gear you're in reminds me of the old automatics that had the gear selector on the steering column...

Re: 8 speed transmission review

Growing up on standard shifters, it's an adjustment, but I'm getting used to it. My biggest problem is shifting too far because of the short throw.

I generally love technology in general, but in this case I absolutely agree with you. I just want to change gears and be on my way. I'd say this is the only thing that annoys me about my GC (besides my other documented issues of course). I'm getting better at it, and perhaps if I had my Jeep more than a day or two in between a week of dealer visits I'd be more used to it by now, but I still have to really look and see what gear I'm in because sometimes it's neutral, sometimes it's drive, sometimes it's reverse. And the amount of effort taken to put in any of these gears doesn't seem to be the same each time.

As for the transmission itself, I did notice once I got it back from the dealer all the shifts were buttery smooth and if this was "regular operation" of this transmission, I'm really going to like it on our replacement GC as long as it works this well. Something they did at the dealer changed it, because it wasn't that smooth when we first got the Jeep. Downshifts were sometimes abrupt, and it seemed like the early gears sometimes didn't shift soon enough. But after we got it back, it was buttah.

How does the V8 or Diesel differ?
