Eaton too , I have changed harness In dash alll sensors all that's left is x y shifter and computer but scared to spend $2000 on it cause nothing that has been done has fixed it ! This has been hell since day one ! And my dealer didn't stand behind me on this ! thank god for northland credit ! and Pete gensmar he has not hit me on payments and paid for repairs funny finance company backs me but not the dealership a holes ! well I guess tomorrow I have no choice but to do computer praying it will fix problem !

Just joined the forum after bumping into this thread. I bought a truck a few months ago(2005 FL with Detroit 6014L 10spd autoshift) that had/has the exact same problems outlined in this thread and virtually everything has been changed short of a new TCU. Clutch, X/Y shifter, all sensors, all harnesses. Last word from Eaton was that "maybe" a new TCU would fix it. Gave up on FL dealer and Eaton and decided to just rip it out and put in a manual 10 or 13spd to be done with it. But, after all that work, it got better and would only act up after 3 or 4 hours on the road. I would then go to manual(paddle) shifting and it would only occasionally do the throttle blip thing in 10th. Manually shifting seemed to reduce the problems but that could have been coincidental. The truck never ever did any of this until it had been on the road for at least an hour. Almost seemed like it was heat related and I always suspected a bad ground somewhere. About the bad EGR. The previous owner had the EGR delete/tune a couple of years ago so that cannot be it but are there any other electrical connections related to the EGR or is it all mechanical routing gas back into the intake? I am reluctant to spend money on the manual conversion when I might be just one little fix away from the solution. Sure seems like Eaton could have figured this mess out long ago. Any ideas would be greatly appreciated.

An update on my problems with the 2005 junk Eaton 10 spd. Two long trips and the same event sequence of events of quick reshifts in and out of 10th after about two hours on the road, then more frequent 10th gear studders, then speedo drops to 0, fault light in 10th and then eventually total lockup stuck in 10th. 4 times, like clock work, if locked in 10th after 4 hours of running. Using manual mode seemed to delay the lock up to some degree. After the truck cooled down, or after pulling battery cables and letting TCU reset, or clearing the multiple codes with OBD II, it would crank up and run just fine for a period of time and then start the Eaton Crap all overa gain.The original owner sent me his repair records and discovered that the truck had been worked on by FL dealers all over the country over the last two years and every single part had been changed on the trans including a new clutch. TCU, XY shifter, every harness and every sensor. He had also pulled and cleaned every connector and Pos and neg cables. After seeing that all efforts had failed, I now have it at a shop in Dallas to convert the junk to a conventional 10 speed manual. ~10 K was spent over the years and the problem was never resolved. These Eatons autoshifts are a nightmare and problems like this are fairly common. But, I am done with it! Even the Eaton factory does not know how to fix their own transmissions. My guess is that Eaton no longer cares. Out of warranty, no longer their problem! So my advice is, do not toss money at it if you are having serious problems. Convert it to manual and end the nightmare!

Which computer did you change? The Eaton transmission computer?

I'd have probably given up before the $2500 computer myself.
