I figured since everybody wants to know about the 8 speed with the hemi I would start a thread for the 8 speed hemi owners, test drivers, etc. to let everybody know how it is!

My review is just after driving it for about 4 hours from the dealership to the garage! Here is all the info on my truck.

I know everybody is going to be looking for the MPG stats so I will post what I have so far. And it may be different for others because I have the factory tri fold tonneau cover. I got the truck with 18 miles on it and after the 250 mile drive I have averaged 17.4 mpg. ALTHOUGH before you start raging about how much bs the mpg claims are. It is brand new and for the first 1/3 or so of the trip I was having trouble even getting 15mpg. And by the end I was getting around 20mpg going 70-75mph. So I am sure it is only going to get better if anything. Also I could have got better mpg if I didn't get as many smiles per gallon :LOL:.

And the second most important thing! The power! I test drove a 6 speed sport with almost the exact same options before and I must say, the 8 speed makes a pretty big difference! I have not launched it hard or anything but I did get on it a few times, the power is unlike any of the GM trucks I have driven, this truck seems like it is much more ready to go. And I am not sure what the governer stops at but I know it is 105mph or higher. And I was not trying to top it out when I hit 105 I was actually just passing a truck and decided to see how easy it was. Lets just say I was thinking I was at 80-90 when I looked down and seen 105mph and this was my exact face :SHOCKED:. So basically, the 8 speed definitely adds a lot of power at all speeds! :smileup:

And now the other stuff! The shifts are very smooth! I honestly expected to feel the truck shift a ton of times and was a little nervous, but I never even noticed the shifts unless I was in the throttle fairly hard. And the manual shifting buttons work exactly how you would expect them to so I don't have much to say about that.

Sorry I do not have more info, I haven't had enough time to play with it yet! I will be sure to make a much more detailed post later on! Also I will add some pictures once I clean all the bugs off!:smiley_thumbs_up:

Thanks for the info! I can't wait until someone tests one of these 8 speed trucks 0-60 and 1/4 mile. How are the shifts at full throttle? Are the quick/crisp?
 
#3 ·
I will try to test 0-60 and stuff later on, I don't really want to drive it hard until I get some more miles on it. I have not really tested at WOT much yet but from what I have done they are very good. It feels like the transmission of a luxury sports car! Oh wait... :LOL:

i test drove the V6 + 8speed and the V8 + 6speed and personally i thought the V6 felt more responsive then the hemi. wondering if the V8 + 8speed makes much more difference. if it does i may stop hunting down a pentastar i want and pull the trigger on the hemi

Go ahead and launch it hard; don't be afraid.

I've never been an advocate of the "breaking in" garbage on any new vehicle I've purchased.....or practiced it. Not a single problem in almost two dozen vehicles over the years.

I enjoyed reading your post.

Thanks.

I also enjoyed reading your post. Great review!

I personally drove the sport CC 4x4 in the V8 6-spd as well as 8-spd and I don't want to sound so exaggerated here but the 8-spd did do an actual difference for me. Punched in harder and quicker and the shifts weren't even noticeable at all. I really enjoyed it. I just wish I test drove it with the air ride. I tested the Laramie's air ride and loved it but it was with the standard 6-spd hemi. Great powertrain nonetheless.

Sorry I should have said acceleration/responsiveness.

I am glad you guys like it! Here is a picture I took after washing it, sorry it was a bit dark. And yes I did wash my truck the second day of owning it :p. Had a ton of bugs on it, also the dealer had armor all on the tires and it decided it would rather be on the side of the truck then on the tire.

(sorry the pic is kind of blurry)

Congrates and nice truck even in a crappy dark pic it looks good:smileup:

I knew when I looked at the specs of the 8 speed that it would be a great upgrade over the 6 speed. after test driving one I confirmed it as has every one else who has gotten the Hemi/8-speed combo.

Got a little feel of the hemi power today. I had a little "encouragement" (couple of girls :smileup:) Well I turned off tcs then held the gas and the brake until I heard the tires start to spin and I let off the brake and floored the throttle. Spun the tires up until about 30mph and continued up to about 95mph before I let off. I have no 0-60 data or anything from it because I did not want to sit there messing with my phone for a minute. Not sure who was more excited, them or me! :LOL:

Nice truck, Squirrel!! I'm looking forward to test driving the hemi 8 speed. A few questions:

1. How is the going from 8 cylinders to 4 thingamajig working? Can you turn it off? I want all 8 pumping all the time.

2. What about the "3/4 tank of gas bump" that drives people crazy sounds like you are getting rear ended problem with new hemis? Did Ram put baffles in tank?

3. How is your paint job? Some had bad paint up to 2012 models.

One more thing: heheheee, this spinning rear tires not moving phase will stop when you realize that you need to save every penny you can for your future. At my age, my advice is to - STOP DOING THAT MESS AND SAVE YOUR TRUCK AND MONEY! If you live long enough, you'll wish you did, believe me!

Good post & for that you deserve a Gold Star, but i don't have any, so here is what i do have
:REP:

now i am just waiting for someone to run through the HEMI w/ 8 speed gears manually :)
 
#15 ·
I agree, I don't notice the shifts at all! Also my mpg is 16.7mpg right now and I have not been driving conservatively at all. Also I love the high ratio first two gears, they make this truck move QUICK from a stop. And that is with 3.55 gears.
 
#18 · (Edited)
You guys that think you have the 3:55s with the 8 speed I have to ask, are you sure you have the 3:55s?

I ask because I though I had 3:55s until I saw my build sheet, here is what I saw:

RPO code: DMCP
3.21 Rear Axle Ratio

The window sticker said 3:55s but that can be overridden by an option, in my case, the 26H order option. With ratios the 8 speed offers, 3:21s do a good job of balance between performance and economy. At 55 MPH the RPM is around 1100 to 1200.
 
#19 ·
So, just punching it from a dead stop, (no power brake) will it burn out with the 8 spd? cause my 6 spd dogs it off the line till about 20mph.
 
#21 ·
The regular cab sport eight speed 4x4 I have ordered says "Customer Preferred Package 26L" on my POC sheet. Does anyone know exactly what the 26L package contains? I tried an internet search, but could not find an answer. I hope it is with the 3.55 gear. I did not order the 3.92 gear as I felt the 3.55 would be enough with the eight speed.

Squirrel, a corvette? Why not a Charger?

Anyway, you give me hope for younger gen!
 
#30 ·
I actually love the SRT-8 challenger, I test drove one when I went to test trucks. Thing was very fast! As the sales man found out:LOL:. Only reason I want a corvette is becuase it is more of a performance car and it is fairly cheap compared to a 392 charger or challenger. Also the corvette will get better mpg and they are less common then the chargers or challengers. Sorry, I am not a one brand man. I just pick the vehicle that fits my needs and wants the best! Although I will never own a ford, other than a GT500 or a Ford GT.

5 of the 6 Hemi/8-speed 4x4 Rams that Earnhardt Dodge in Gilbert Arizona has all have 3.21 axels. I didn't think you could get the 3.21 on a 4x4, but they must have changed it due to the 8-speeds better gears. Even the SLT with Big Horn equipment group comes standard with 3.21s. They did equip one with 3.55s though for an extra $50.
3.21 would be pretty nice for the guy who never tows. I cant help but notice this on the sticker though-
This window sticker may or may not match the actual window
sticker on the vehicle itself. We reserve the right to make

Is there a tag denoting axle ratio on the axle itself?

Squirrel, that sounded great!! I understand about the brand loyal, I'm that way too. Having said that, to me, Chrysler makes the best looking vehicles! But hey, I'd get a Yugo truck if I knew it was the most reliable! Trouble free is what I like!! But, all of them are just man made machines - that I happen to like! I've never seen a truck I don't like!

RCSB with 8spd and 3.55 in the rear

MDS is hardly noticable and only seems to come on at very low rpm/load...

even with my Magnaflow I don't notice...


To disable MDS either press "gear -" and put it in manual mode.. or drive with Tow/haul

no gas tank bump for me.. but I have the smaller 32Gal tank..


my silver Paint seems ok...

but my brakes do moan and groan which is quite annoying

The answer to the engine running 8 cyl to 4 cyl and back. You will notice it when you stomp on the gas especially when doing about 60 and then flooring it. When city driving in the 30-40 mph, you feel it but slightly. I had a Chev with the 5.3 and you could feel it all the time in that truck. I have 3:92 gears with the 8 spd and it will put you back in the seat when you stomp on it. I didn't drive a 6 spd because the articles I read about the 8 spd were favorable. The 8 spd is made in Germany by Mercedes.

I am overall thrilled with the 8 speed. One thing though: Say you make a 3 point turn and you're trying to do it in a hurry. The switching from D to R and back to D takes a second, or two, for each change. It won't do the switch until everything has come to a 100% halt, which is a good thing for damage control.
