·Hi. I'm new here but this thread has made my day. I have exactly that problem. Seems like an easy fix. Just traded an 05 Dak with tranny issues. I was beginning to think I had made a mistake.

I agree with the majority.
This flash is perfect for me.
Got revs got power.
Mileage improved on highway.
When I meet some one that complains about the Nitro power, I ask them if they had this flash performed.
Usually the reply is "no"
"GET IT DONE"
I reply

·Had the "Flash" done today. Dealer was decent enough to split the cost with me so it only came to 38.00(CAN). It seems a whole lot better in the city. No more growling and lack of power. I haven't had it on the highway yet but hopefully the milage gets better. I was little scared the last time I filled up--- 15MPG ---. Since then I have dropped in a K&N filter and changed to Synthetic oil. Still happy otherwise.

You should be very happy with it now that you have the Flash done!
My mileage has dropped just a little bit (maybe 1/2mpg) ... but that's combined city/freeway driving. (About 16-17mpg) I need to do a good road trip to see if I get 20mpg (or better) like I used to!
The 09 should already have the latest flash from the factory, but it wouldn't hurt to have your dealer look into it.

Sorry, new to this.
No worries, and welcome to the forum. :smileup:
What Nitrover was saying is that if you add your trim and year to your details then we will be able to see it on all your posts.
If you go to the "UserCP" (control panel) and select "Edit Your Details". You can then enter the year, trim level and other details of your Nitro.
If you look in the upper right of my posts, my details have the following.
Vehicle: 07 Nitro,4X4,6sp-man,3.7L
Trim Level: SXT
Color: Light Khaki
This will help members that are trying to help you with questions on your Nitro.
As far as your question...
The best way is to contact a dealer and have them pull up the history on your ride, to see if it has been done.

I had the reflash done earlier this year. Just came back from a 1700 km road trip and it drove like a charm. This certain highway we take(Coquihalla)on our holiday every year a tough hill which goes steadly up for at least 60 km and some spots very steep. In the past the transmission would be jumping gears if i did not put tow haul on. It would never make its mind up. It would whine very loud. This year it drove excellent. The transimission knew what to do it would shift when it really needed to and did not whine I did not need to use the tow haul button once.

Im just curious. Haven't visited this site in some time (feels ashamed) but I just took my Nitro in for a vibrating while driving specifically at 40Mph. In my case it would happen even if I dropped into neutral while driving 45 and let it coast down to 40. The dealership said that they would have to replace the spider gears and ring and pinion (covered under my warranty). However, I wonder if this might be the underlying problem. I am by no means a mechanic of any kind and do not claim to be so. Does anyone think it could cause undo wear on the parts they are replacing? Or could it really be the issue all on its own?
I should also note that I do not primarily drive this vehicle, its the wifes, and she is the one who mentioned the noise to me after a recent set of tires was installed.

Welcome back to the forum! In order to get better gas mileage, manufacturers added a clutch to the torque converter on the automatic transmissions. This was to decrease slippage, and give the driver slightly better mileage. So, what this TSB addresses is when and how this clutch engages, and I am not sure that there would be a correlation to this issue and your rear end gears having to be rebuilt.
Since this is being repaired under warranty, I would be more apt to blame a bad part, assembly or casting, from the factory.

Thanks for the input. I wanted to get the input from you guys because ya'll have always been a reliable source. Thanks for the quick reply.
Parts are on order for the repair so I hope that is what the issue is. I am so glad it is under warranty because I think they quoted me about a grand to do it.
All in all my nitro has been absolutely great!

I have a 2011 with a 3.7L. I have a 3yr/36000 mile warranty. My tranny skips when shifting from 1st to 2nd.Then it hard shifts when going from drive to overdrive. Generally it does this around 40 to 50 mph. Could this be the fix that I need

I have been experiencing this issue as well. I don't have a warranty, and after a quick call to the dealership, they quoted me $50 for the flash, but said it could be up to $100 depending in how much they have todo... Does this sound okay? I have no idea how much the flash should be.

I just got this flash done a few weeks ago. I was charged $100 by the dealer to check for/and update any flashes for my vehicle that were not previously done (there were 4 flashes for my Nitro, but I was told the $100 would be the charge even if there was only 1). I have heard anywhere from $50-$100 for this service (which only the dealer can perform). IMO it's worth it; Nitro shifts much better now, and no more lag or indecisiveness between 3rd and 4th gear with slight acceleration. I've heard from other members that they saw an increase in highway MPG but it's hard to tell with mine as I have been doing other things to it as well.
