Which will skip shift? |
|
Jack Mayer 08 June 2011 01:22 PM |
A FreedomLine trans will skip shift if it does not need the gear above it.
Which other trans will skip shift. AutoShift Gen 1 NO I thought an Ultra would if programmed to do it, but is that correct? |
hjsdds 08 June 2011 01:30 PM |
Autoshift Gen 1 does in manual mode. You give it two thumb clicks. hjs |
Jack Mayer 08 June 2011 01:38 PM |
Yes Henry, but I'm talking about on its own...... |
SuiteSuccess 08 June 2011 01:41 PM |
Ultrashift-NO! or at least mine won't. Could only reprogram mine to start in 2nd and no higher. It goes through every gear to get to 10. |
Jack Mayer 08 June 2011 01:43 PM |
The Ultras I have driven did not skip shift, but for some reason I thought they could be "told" to do it, guess I'm wrong.
I've never driven an I Shift, but they are pretty "magical." Wonder what they do. |
campswithcritters 08 June 2011 03:31 PM |
I'll back up the statement on Ultrashift, have not plugged in to see if options are available but mine starts in 2nd and hits every one through to 10th. |
maynardga1 08 June 2011 03:38 PM |
Jack The I shift has three different modes that you can select from: 1) full automatic and it grabs every gear up and down 2) manual and you shift it 3) automatic and it selects the gear based upon load and grade in essence it will perform a skip shift mode just like the FreedomLine |
Jack Mayer 08 June 2011 06:47 PM |
Excellent. Thanks for the information on the I Shift. I hope to get my hands on one of those some day. The few drivers I have talked to that have them absolutely love them. |
TomMarik 08 June 2011 08:32 PM |
I was surprised that under easy conditions, my FreedomLine occasionally shifts 3, 7, 10, and 12. |
MCraven210 08 June 2011 08:51 PM |
Can the Gen 1 AutoShift be reprogramed to start in 3rd? Mine starts in second after start up but when you put it in 3rd it remembers until you shut it down. Thanks |
Rif 08 June 2011 01:30 PM |
Yes. I had mine changed to start in 3rd. IIRC it can be programmed to start in any of the first 5. |
hone eagle 09 June 2011 05:08 AM |
Yes Henry, but Mdrive built in Sweden- hummm even looks the same as the Volvo product talking about on its own...... |
Jack Mayer 09 June 2011 09:10 AM |
As Rif said, a Gen 1 can be programmed to start in up to gear 5. A Gen 2 can only be modified to start in gear 3. This is for a "default" setting. |
Jack Mayer 09 June 2011 09:11 AM |
Mac Does the I-Shift have the National Network gradient info in it by default? |
Hogrydr 09 June 2011 10:23 AM |
Jack I don't know about the gradient, but the I shift will shift according to the weight of the load and learns the pattern. |
Jack Mayer 09 June 2011 12:21 PM |
Anyone know when they stopped putting FreedomLines in? 2006? I don't recall seeing any 2007 FreedomLines.... |
HERO Maker 09 June 2011 01:11 PM |
Jack I see there are a few 2007s listed on Truck Paper but no newer years. On edit, looking further at the pictures two of the trucks, a 670 and 630 look like they have Ultra Shifts in them, not FreedomLines. Although the write up shows FreedomLine. |
HERO Maker 09 June 2011 01:37 PM |
![]() Not going to try and post the pic this time, but here is a 2008 - 670 |
maynardga1 09 June 2011 04:18 PM |
Rocky That is not a FreedomLine; it's an Ultrashift, I believe ZF pulled out of the North American OTR transmission market around 2006 prior to the economic turndown . |
HERO Maker 09 June 2011 05:53 PM |
![]() My bad!! Jack, then there are a few 2007's listed on truck paper with FreedomLines. |
D and J 09 June 2011 08:11 PM |
No,
Ultrashift console looks just like the Gen II AutoShift console. I just got an e-mail from Arrow that they have a "program" on 2007 780's |

Jack Mayer 09 June 2011 09:08 PM |
Doug, that is probably because no one wants those new engines..... |
waylandlong 09 June 2011 09:22 PM |
A 2007 is not the new emission. They did not start until the 2008 year models. ( Has to be 2008 on title). There are actually a few 2008s running around with pre-emission in Internationals and Freightliners. |
Scrap 09 June 2011 11:52 PM |
They've changed the touchpads again as well. They are now black and don't have that fan or half buzzer or whatever it was inside that annoys the heck out of me. The DM's will skip but they have to have 7 prior low load shifts and then be able to land at over 1K RPM after a skip. So with a 10 speed and an 1800 motor you'll be hard pressed to get it to happen. AS3's will as well, and have to land at 800RPM. Similar situation. I really don't think you'll be happy with a DM Jack. The Plus or I-shift is gonna be your thing. Selectable modes was an option, wasn't it? I'm not sure every truck got it.
Controller grade road slope data isn't complete enough for a production system yet. Supposedly by the end of the year it will be. I don't know how they do it but the I-shifters have to be figuring the road out somehow else. Not to discount it because it is a good system, but calculating truck load and stuff is kind of ho-hum anymore. All engines do it now and pretty much nobody will buy a highway truck nowadays without it. Four years ago it was a big deal and quite marketable though. You can see all the various FreedomLine ending years in the latest of the lawsuits here |
army 12 June 2011 10:42 PM |
Do any of them have a more predictable clutch engagement than the FreedomLine? Any of you that read my previous thread about why I sold by 2004 will know what I am asking. |
hone eagle 13 June 2011 05:16 AM |
I understand the I-shift will creep - they call it 'the urge to move' in the video's. |
hone eagle 09 June 2011 05:08 AM |

Scrap 13 June 2011 09:17 PM |
The Plus is pretty normal feeling but is best with HSA option. Add ATC and it does everything for you. Just look ahead, tip in, and it goes. |

So my truck has the Meritor 12spd, it skip shifts (when in auto) based on load - but here is my question, is it an Autoshift or Freedom Shift (what's the difference)? and what are the generation time lines?
I've got the large <ugly> paddle/stalk off the steering wheel - it can be shifted <even in full auto>, my experience is limited <until Friday when I lay out 1000 miles, and even then ill be dangerous in what I know> but I'm impressed w/how "smart" the transmission is, at least in gear down, sensing the speed and dropping gears meant there was almost no need for brakes (and that was w/out the exhaust brake on)> The Meritor seems to get good reviews, and i haven't read about too many problems (I've heard that there are some connector/moisture issues - but I don't know if that applies to mine or not). I'm wondering which generation I've got and when/what the differences are and what precautions I may need to take to prevent any issues |
Eskimo 14 June 2011 05:43 PM |
The ZF 12-speed I drove in the 2005 or 2006 Volvo coach skipped gears.. started in 3, then (IIRC) to 7, then 9, 10, 11, 12. |
DonF 26 June 2011 01:19 AM |
Meritor two-pedal is the ZF (aka, Rockwell) FreedomLine transmission. It will skip gears, depends on load sensor, etc.
Donnie tried for an I-shift when he ordered his 2008, got the FreedomLine instead -- 'Because that was what they could get at the time of his order (IIRC). This is the one with the rocker control mechanism (rather than the touch-pad arrangement used by Eaton-Fuller for the UltraShift & AutoShift. So, again, he has TWO Volvo's, each with As the story goes, E-F ran Meritor outta the business with their lawsuits (which, ultimately, got thrown out), so Volvo (in 2008, or late 2007?) brought their independently-developed I-Shift to US production (from Europe) and is having great success -- though it's highly tuned to "talk" (aka, negotiate) with the engine to optimize performance & economy. Anyways, that's the story I'm repeating --- and I'm stickin' to it. |
BushPilot 26 June 2011 06:35 PM |
Mine says "auto shift" and its a 12 speed - its a beautiful thing ! |
BushPilot 26 June 2011 06:49 PM |
Hey does anyone know where the fluid dip stick is for these auto-shifts is ?? i can NOT find the damn dip stick, if there is one. |
Phil D 27 June 2011 06:16 PM |
BushPilot, on 26 June 2011 - 06:35 PM, said: Based on the gear indicator in the picture on your gauge post (along with the fact that you know that it's a twelve-speed), you definitely have a ZF Meritor FreedomLine transmission in your Freightliner, not an Autoshift (an Eaton-Fuller trademark, although often used incorrectly to describe almost every automated HDT transmission). BushPilot, on 26 June 2011 - 06:49 PM, said: There is no dipstick. Since it's not a fully automatic transmission it has a fill and a drain plug, just as any manual transmission would. Based on the drawing in the FreedomLine Parts Manual, it appears that the fill plug is high on the passenger side, while the drain plug is low on the driver's side. |
BushPilot 27 June 2011 06:30 PM |
Sweet - THANKS Phil !!
As I was under it last night I was wondering, 'specially when i saw the CLUTCH (inspection holes), so what fluids does this thing take (isn't it always easier to ask then go read ? Any known issues w/ the ZF Meritor that i can head off (connector/ moisture issues etc. ??) |
campswithcritters 27 June 2011 08:08 PM |
My UltraShift is fairly predictable, especially without a load like during hook up of the trailer. I do 2 foot it by keeping a light brake on it creeps well. Can get bouncy on engagement when trying to creep with the trailer. |

Jack I had a 2004 with a D-12 and a 12 speed FreedomLine which I recently sold to another "horse person." I did not care for the tranny at first for hauling horses. I thought it was too rough through the down shifting for horses. However, in the end two things helped me to really like the tranny and I would definitely have one again. 1. The FreedomLine people helped me change out the clutch fork to the 2008 model that has rollers on the end of the fork for smoother shifting. 2. Practice!!! I found that for hauling horse I needed to keep it in manual for the smoothest most predicable shifts. The FreedomLine can skip shift 2 gears in manual and up to 3 gears in automatic. I shift it in manual most of the time even if I am not hauling horses. The shifter is so well placed and easy to use I just prefer it. |
