Had the update done Tuesday. I put 200 miles on it since. Mileage jumped from 19+- to 26 :shock:

I was really unhappy with my MPG but this seems to have done wonders for that. I can feel the gears shifting now, never could before. It could be summer fuel is finally here but I don't think that would get me +7MPG.

I also noticed a jump, but mine went from 24mpg to 27mpg. My trip computer is now reading 28.8 over 150 miles.

Mine has jumped from about 19mpg to 24 mpg just in the past two weeks. However, FlyingJ truckstop told me they finally switched back to summer blend of diesel. I suspect this is the reason for my return back to my original mileage from last year...

I have never heard of winter blend causing a 30% to 40% drop in MPG's before, but I guess anything is possible.

My mileage here in Kentucky went from 19 to 24 over the last 4 weeks also. Winter blend diesel sucks.

The general rule of thumb used to be about 5% to 10% drop in MPG's, same for my 83 MB as our '02 VW diesel. The 20% to 40% you guys report is/was unheard of and seems unreal to me. That's not to say the CRD engine is a whole different story due to radical different fuel delivery system from the old MB or VW diesels.

I mentioned that on mine, the engine noise level is noticeably reduced

I just returned from having TSB 18-009-06 done, and I noticed the same thing - engine noise is much lower, also better acceleration off the line, and much smoother. The transmission had recentely started a slight jerking, but it's gone now. Much, much smoother shifting and the engine feels a lot smoother at the same time. It definately feels like a different engine. It also took an hour and a half to download and perform both flashes. Well worth the time.

Had mine done today here in Australia, and I agree with everything above. Makes it a much better drive.

Having said that when I got it back last week.....today it did something weird. From a standing start I had the O/D turned off, and then I accelerated foot flat to the floor up to 80km/h and then backed off to cruise at 80km/h when the tranny seemed to suddenly 'stutter'. I flicked the OD on and it changed up and it stopped. Hasn't repeated the performance on the way home. I must admit I rarely accelerate 100% through the gears but this kind of felt like the the shudder everyone is experiencing. If so, seems the TSB isn't fixing the problem..... :roll:

Same here. First few days, no stutter, but today, it started again, very slightly, nothing like it was, but it seems the tsb didn't fix the transmission problem completely. Will wait a couple of weeks to see if the tranny adjusts a little more.

Ripster · **Posted:** Fri May 05, 2006 8:53 pm

I went out on a trip today and I have had the latest flash, I have only 800 miles and I was able to accelerate hard
when merging on a ramp and it did the famous "shudder" but if I accelerated slightly it would quit and settle down.
Amazing, I wonder after reading several different diesel magazines, if we need a different torque converter.

Has anyone with a CRD had either a TSB or new converter, etc that has conclusively settled and fixed this issue?
Now if I don't push hard and then let off, I will never feel it again, but something is not dialed in correctly. I can do
it on command. Normal driving I do not have any complaints, but hey, you do pass once in awhile and I do see
a freeway from time to time. There has to be a solution to this somewhere.

Anyone fixed this entirely yet? I am about ready to talk with transmission converter after market tuners.

I have had the filter TSB and the trans & ECM update done and have had none of the problems you describe. I however had them done with less then 1000 miles, also the Liberty was always allowed a to run a good minute before being put into gear. Also it is garaged and never in any really cold starts and drive off's, if 20*F in am it usually warms up to mid or high forties in the pm. I still think you all have damaged the torque converter and or possibly other internals from having to suffer too long the shudder the improper filter and possibly put into gear to soon. I have never had the shudder problem and when the Jeep is floored it goes straight through to red line with no shudder or bogg down. Of course tomorrow the tranny could puke it's guts out all over the pavement.

Well, I used to say I had no shudder, but now it's here. Does not require heavy acceleration, just trying to maintain speed in the 55 to 62 mph range with gradual acceleration and deceleration due to traffic.

Happened three times yesterday, and now four times today. I don't know what to think. I can still accelerate moderatgely, or aggressively, through all the gears up to and beyond 80mph and the transmission shifts perfectly, but in the range listed above, I'm getting this shudder. I always idled at least 30 seconds prior to taking the transmission out of park, and it's always in a warm garage, so no cold overnight starts.

When I had the filter TSB done, the fluid and transmission pan were clean at 7000 miles, no real metal shavings-according to the technician. Now at 10,400 miles things are acting up. I'm just going to drive it until something breaks as I can't waste time chasing a ghost problem.

Any ideas? Someone one this board made the comment that the manufacturer of the CRD engine stated a while back that our torque converter was not up to the task of the CRD low rpm torque - but I can't find this statement anymore...

Ripster · **Posted:** Fri May 05, 2006 10:37 pm

If you look in truck publications the torque converter is one of the first things they change. Old Navy, I have
800 miles on the vehicle and after 2-3 hours there should not be any issues reference letting it warm up etc.
Too new, it has not even started 20 times yet. So the updates you have done are replaced both filters in
the tranny and did you get a new torque converter? Has anyone replaced the torque converter and had this
go away? It is almost like it, how did the publication I was reading state it, they call it "torque stall" which I am not sure all that it means
yet, but the converter is not up to the task, or not tuned correctly, this should be like butter, not clunking in or out.

I mentioned at the start of these problems that even though this tranny is used with the Hemi PU that has more torque the CRD, I stated but not at 1600 rpm and at that RPM the Hemi may only have 100 lbs of torque. It may not be up to the low end torque as the NAG-1/ MB 5 spd tranny used in the Sprinter and LX series of cars. This just may be the problem, however I still not totally convienced as yet.

I think they just had bad batch of trannys, I hope. :roll:

Ripster · **Posted:** Fri May 05, 2006 10:46 pm

Love the vehicle though, 26.6 while driving 70 on the freeway to Milwaukee today, love that diesel sound.

I didn't have the TSB for torque converter replacement done, just the one filter and fluid. Also had the software updates to tranny module and ECM. I think the problem is also worsened by the new owners driving at about torque converter lock up speed, the improper programming to start with in the Jeep, wrong filter, and finally people starting the Jeep and putting it into gear before the tranny can pump fluid up to torque converter.

All that said It still might come down to not enough tranny for the 300 lbs of torque hitting the torque converter so quick. However I am of the opinon that we most likely may all only need improved torque converters and software updates to go with the change. Also understand I am not by any means even close to being a tranny tech. Also I was supprised they didn't use the NAG-1 MB tranny that is used in Sprinter and LX car and has a torque handling range to 650 lbs.

Ripster · **Posted:** Sat May 06, 2006 8:59 am

I will try changing the filters and fluid, I have had the flash updates done. I got the stutter when running up to 70 or 80
when merging with traffic, then letting off easy, and you would get it unless you kept pressure on, so I was
past the lockup, but it was trying to shift into the last shift. Definitely some little issue here, but I believe this
board will eventually solve it, one way or the other. I was not disagreeing with you Old Navy, just narrowing
down the common factors that would apply.

I have not installed my Transgo yet but I have been helping a friend in Sweden get a transgo and he did all he could with the trans in the vehicle. Hopefully he will post to the list his findings. He did not do the pump mod to raise the line pressure as it required the trans to be pulled from the car and partially dissasembled.

He did say there is a marked improvement in shifting and that going into 5th was sooner, about 50 mph, and there was no shudder.

Wow, I got to get off my dead butt and get mine installed.

Ripster · **Posted:** Sat May 06, 2006 7:14 pm

marauderer you may have the answer and don't know it yet. May the force be with you.
Let us know, inquiring minds are fed up with the current shift points. By the way
what is the cost of the upgrade kit.

Ripster · **Posted:** Sat May 06, 2006 9:25 pm

marauderer get that kit in your tranny, after reading on another board the results of
someone who did it today, I believe you have the answer in your hands, I am ordering
mine on Monday.

I can confirm that the stutter is still there after the latest TSB on my 05, just got back from a 400km round trip and it did it 2 times during the trip. Once was coasting after accelerating to pass, another was just cruising at around 80km/h with very light throttle. Its annoying when it does it, but it doesn't do it every time you try and reproduce the problem by driving the same way when it last played up!

To anyone who already had TSB 18-009-06: What is written on the sticker under your hood?

Questioned my dealer again today, they insist I have latest software update (done 4/17/06) but they marked the sticker as 18-018-05 (old TSB). Claimed they connect my Jeep directly to DC to do the download and install whatever the system tells them is current.

I did mine about 4 weeks ago and it was the 06.
