Re: 8 speed tranny? Dream on...

according to some of the reviews for the 2012 300 and Charger with the v6 and 8 speed....performance is better and gas mileage is way up. Ive seen the chryco commercial for the v6 8 speed 300 claim 30 mpg's

And my Jeep SRT8 came from a dealer who is a large SRT8 dealership and his got cancelled.

And no 392 has been mathched up to any 8-speed and no info to date suggest otherwise.

The rest of this post was my opinion as to it's durability and capabilities WHICH STILL HAS NOT BEEN PROVEN BY THE WAY.

SO BEFORE YOU PUT SOMEONE DOWN (which some jackasses are good at) post up some facts and documentation to the contrary!
Name calling is totally uncalled for. I shared my observations and you didn't agree. Fine. You asked for additional details....here is what I remember. I haven't followed this topic since my vehicle arrived. The orders situation may have changed, my data points are all from the June - December 2011 timeframe.

I ordered a Jeep through a dealer that recieved my order and one for dealer stock. I can provide the VON of the dealer stock order if you would like to verify. The one ordered for stock was on the lot for approximately one week before it was sold. There is a chance that a customer name was added to the order before it was delivered (no way for me to verify at this point). At the time that I ordered my vehicle that was not the case (I believe I still have a copy of the stock order that they printed out for me to give me an idea of what they had already ordered). One thing I picked up on reading all the demand related quotes - They always mentioned they were sold out for the 2012 model year. They never said each order is "Pre-sold to a customer or end user". If you have facts and data otherwise, please provide a link or post the info. Jeep sells vehicles to dealers...dealers sell to us. I have no doubts that dealer demand exceeded the number they planned on building, again...my point is that not every order was pre-sold to a customer.

Another point to consider. Up until late 2011 there was a method for inserting a VIN into a link to which provided order and vehicle status information through the Insight Logistics system that the dealers and Jeep use to track vehicle movement. I checked some of the VINs from eBay listings and Dealer listings (verifying dealer info match to the listings) and noticed that there were at least 10 of the first few hundred delivered that indicated they were not Sold orders. My interpretation of that information is that the vehicle was not pre-sold to a customer. There are various conversations on this topic from that time period on both this site and the red site. External access to the Insight Logistics site was shut off in mid-November of last year otherwise I would just send you the links that I used at that time (you can verify this also through reading through conversations on both sites, people were bummed that this method for information gathering was shut off).

My personal experience was that you cannot rely on the information you get from calling customer service (who told me I was in D1 status while my vehicle had actually reached Built status) or a one line quote from a promotional video. Time and time again I have learned information from this forum that ended up being spot on after I had a dealer or customer service tell me something different.

We agree on one thing....I don't think we will see the 8 speed in the next model year.

Re: 8 speed tranny? Dream on...

I have to agree with 12jeep. I had ordered one on May 30th and at the same time the dealer order 3 for dealer stock. The first one for dealer stock came in on Nov 16th and the one that I had ordered has still not been built.

I literally called every dealer in SK, AB, and MB. Probably 75% of them had jeeps in transit that were not sold but dealer stock orders.(asking above MSRP though)

As a matter of fact the jeep that I ended up buying was a dealer stock order and the one that I ordered still sits in C status.

Re: 8 speed tranny? Dream on...

Not that this really matters, but the new Merc M63 has a 7 speed with 518 horses and 516lbs of torque running through it. I find it hard to believe that the SRT boys couldnt build a tranny to handle the lighter powered 470 horse Hemi.

From my observation 1 gear is too tall and 5th is too short.

the reason i see alot of people wanting an 8 spd tranny is two things. 1. the current Mercedes sourced W5A580 (Chrysler NAG1) is slow and sloppy at best. when the brown top solenoids in this trans are replaced with the AMG Blue Top solenoids the performance is much better but its still slow. shift times are greatly reduced with the ZF 8HP45 , and the second being more efficient means more of that power at your crank means it can finally reach your wheels.

SRT team is not going to develop a new tranny for them selves tehy will use one that is allready being produced, like the 8 speed that is being sourced from ZF friedrichshafen in germany, The ZF 8HP, it is being licensed to Chrysler to be built in us as a chrysler 845-RFE, this trans is only offered in the V6 models as of right now because it can only handle 450Nm Tq. if Chrysler gets the ZF8HP70 or *80 we could see use in V8 apps and SRT apps. until then MR.Jason is correct in his statement that this trans cant handle the power.

There are several new 8/9 spd transmissions under development in addition to the current "light duty" 8-sp, this includes medium duty, heavy duty and extra heavy duty variants for Ram trucks and Hemi vehicles.

SRT8's may be "low volume vehicles" but the same transmissions are used across the lineup, so 4 vehicles x several model years = more than enough volume to justify a custom transmission variant or two. Note that SRT built almost 80,000 vehicles for the 1st generation of V8 models.

Re: 8 speed tranny? Dream on...

I borrowed this tidbit of info:

Chrysler may have overpaid for the NAG1 but it is hardly the slow shifting, unreliable transmission that the auto mags love to call it. Compared to a manual transmission, a human cannot shift faster than a NAG1. The NAG1 has powered some incredibly high horsepower LX vehicles with very little problems. Treat it badly and don't maintain it, and it will break like anything else. There are plenty of LX/Jeep owners who have had absolutely no problems with the NAG1/WA580.

Early reviews of the transmission actually praised its relatively fast shifting, indicating that the “slow shift”*issue may have come later, perhaps due to the torque management intended to prolong transmission life.


Anywho, and my other thing I was gonna say. I sure hope an 8 speed shifts quicker because it's shifting more than my 5 speed to get there lol

NAG1/W5A580 is an overall great performing tranny. i aso have an 06 Chrysler 300 AWD, the part i think is slow is going from reverse to drive there is like a 3 sec pause until it goes you put your foot on the gas and its like 1..........2.........3....... go. i find the 545-rfe in the jeep to be a faster tranny.

I assume you don't come to a complete stop after reversing before switching to drive?

I know the delay you talk about. I try not to go from reverse to drive while rolling. Even the owners guide points that out. It's the tranny doing its thing to protect itself.

Either way it doesnt matter. 6, 7 or even 8 speed would be a step above what they are using. IMO, for 65K the thing should have a double clutch setup.

i usually do use the brake before going from reverse to drive. but i am more referencing those spur of the moment quick 3 point turn on a street and traffic is bearing down on you to move. its like c'mon lets gooooooo!!!!!!! its like your in drive then complete stop slam in reverse hit the gas and 1.....2.....3....and your going then off the gas bang it into drive 1......2......3....... and were back in action. this is the thing that kills me about the nag1.

I prefer the autostick in first, traction control off, and whip the ass end around lol. No 3 point turns

I hear ya though. In my WK1 SRT8 I'd get the delay going into neutral to rev it up (while moving at speeds) and it took a couple seconds to engage drive once shifted back. The Nag1 doesn't like that. But it does it to protect itself.
