Gotta love the emissions god. To jkern, Ryan at Hardway Performance worked at H&S now has his own shop. He custom tunes H&S and emails the tune to you. He did an engine and trans tune for me and woke the truck up. I believe he can get trans to do exactly what you want. Probly has a fix for all years.

Well, if you do your own pooping, You can't blame your transmission. Lol

TCdiesel. So the dealership has this flash?

 

[TCDiesel]

Yes..........

What exactly is the "weak spot" on the 68 RFE when you add torque over 800 and more hp that aftermarket guys claim to be able to make it bullet proof?

At a cost of 6-8k? My Aisin cost $2395 more than a 68RFE! 6-8K OR 2.395K???? SNOKING

Cummins is a must. Thats the ONLY reason I buy RAM/Dodge. I'd buy a AISIN in a heart beat so I would have a bullet proof truck. One thing is for sure, your engine and transmission will NEVER go bad!!!

Aisin AS69RC was new for 2013?
Might be bullet proof?

But not as tested as the Cummins

Mercedes advertises customizable shift pionts. Maybe that is in the future for Ram

Both EFI live and H&S can recalibrate trans to your needs. Relatively inexpensive. If you want a " bullet proof" ha.ha. transmission instal an Allison or eaton. Trade your truck for a new one with an Aisin will cost you more than the upgrade cost on the sticker by a bunch. You could get a Pact built trans that would last a lifetime of abuse for less.

Best suggestion I've heard in a long time.

Another grumpy new Ram/68RFE owner: 2015 DODGE RAM 2500, Cummins diesel 6.7L motor Transmission 68 RFE automatic: I am extremely disappointed in the shifting performance of this new transmission. The shifts between 2-3 and 3-4 feel like everything is slipping. Feels like the transmission is getting a run @ each gear and slips and it is more pronounced when pulling my 5th wheel. I recently drove a 2012 Dodge Ram 2500 with this trans and it feels great. I am wondering why the Dodge Chrysler corporation allows this inferior performance in the new Rams when the older 68R feels far better? Also why does Dodge place such emphasis on performance, high horse power and motor torque but then have this 2015 transmission slip like mine does. I have spoken with several other truck owners who have experienced this same disappointing trans gear shifting performance.
Do any of you TDR subscribers know of a “fix” for this transmission slippage feeling other than the “reflash” you can get done at the dealer? I have had that done and there was no improvement. Appreciate any knowledgeable feedback.

Because smooth shifts don't spill the urban cowboy's cafe latte! Put in a Trans-Go kit and let the transmission shift like it should, but don't complain about hard tire chirping shifts! a middle ground is a tough deal to do.

There is no "fix" required, as it's working just as designed. What you're experiencing is "shift flare". It promotes smoother shifting and helps save the transmission with the 800 lb-ft of torque behind it.....

Sorry to her they have not fixed the "DELL Tech support" shifting flare issue. Like I said in a previous post, my 2012 shifted great, 2013 like a sloppy slip n slide.My latest 2013, shifts fine with a little "flare" in Tow haul mode" of all things. Maybe Trans engineer will pipe in with some info. He's a engineer with Chrysler and knows these trannys inside and out. Its a long process to get a change, but it was supposed to have been fixed in the fall of 2014.

From the "What It's Worth" Department.....the Aisin has similar shift flares......it really just depends on the amount of throttle input. It's never been an issue for me....personally. I'm at 115k miles and I reallllllly am pleased with the performance of my Aisin.

Well, it's hard to please everyone at once. A shift that one person calls "smooth" will be perceived as "mushy" by another. And a "firm, crisp" shift for one person is critiqued as "harsh" or "rough" by another.

As far as shift "flares" go, typically an actual flare (engine RPM increase) during an upshift is caused by a change in the Torque Converter Clutch (TCC) slip rate. For example, if the TCC is locked in 4th gear (no slip), then a 4-5 upshift may actually use this sequence:
• Unlock (or change to partial lock) the TCC (this will raise engine RPM)
• Perform the 4-5 upshift (engine speed will drop)
• Wait a second or so
• Relock the TCC (engine speed will drop further)

In this case, the TCC unlock (or partial lock) is used to avoid a harsh jerk that might be felt if the 4-5 upshift was made with the TCC fully locked. So the "flare" is deliberate, and produces a smoother upshift.

To diagnose shift complaints, get a scan tool that can display current gear, target gear, and TCC state. You can then watch the display during a shift sequence and see exactly what's going on. For example, you can verify whether your "flare" is actually the TCC changing states.

I guess too many owners complained of hard shifts when towing, but the 2011-version 68RFE in our truck shifts fine when towing our 19K GVWR 5th wheel. I don't notice any shift flare on the upshifts - yes, you can feel the torque converter unlock and lock in the upper gears, especially on the upshifts and downshifts between 5th and 6th, but the upshifts when accelerating while in T/H and pulling the 5th wheel are (in my estimation) nice and firm with no flare. I can see where someone who wants it to shift like his Lincoln might complain of "hard shifting", but it suits me just fine. And, yes, I'd likely buy the Aisin in a new truck simply because when I order a truck I normally get the most payload and GCWR that's available, but until then, the 68RFE has served us well so far.

I understand that the later 68RFEs (later than our 2011) have a revised (softer) shift schedule. That's too bad.....
