Re: Newest TCM flash. Don't get it if you're not having issues

If this is being seen in our JGC you know damn well it will for the Ram 1500 as well which is too new to see a problem with the ZF 8 spd algorithms. I plan to stick around for a while and see how this goes with the Ram and Jeep.
I don't have but 4800 miles and no issue with shudder yet but will see if it shows up as reported by others.
Plan to instruct my dealership to not do that update.
My mileage is 28 plus on the interstate and don't want that dinked up.

Raven hope you find the perfect truck because I have not in any of the makes that the produce diesels. My SuperDuty was about as close to it as I could get but it still handles and stopped like a pig had the turn radius of a battleship but never one mechanical issue transmission and engine in 180K miles...

Re: Newest TCM flash. Don't get it if you're not having issues

Jeep released two TSBs on Friday relating to transmission shift adaptation. The procedures suggest that certain kinds of work on transmissions may cause shift patterns to be unacceptable but that, as I read the TSBs, they will eventually self-correct. But for the impatient there are a couple of ways that the techs can goose adaptation in the right direction. All of the procedures require update of the TCM to the latest software first before going through the adaptation procedures.

I have 600 miles since that flash... still garbage mpg. They detuned the tq out of the low rpm in high gears, not going to get better. Makes buying a diesel useless if you tune out low end tq

I'll consider the source. So dump the car already and comment on the Duramax forums.

Re: Newest TCM flash. Don't get it if you're not having issues

Well...I guess if we aren't going to be tolerant, nobody but coolaid drinkers will be left. Raven is a tuner who has spent his time and money cracking our ECU and datalogging. He still has his Jeep but I guess we just helped him decide. This is his thread...and Jeep did just what he said...detuned the bottom end to force an early upshift.

It would be different if he didn't know what he was talking about.

Sorry, ExcursionDiesel. Can't say I agree with you there. I wasn't questioning his knowledge or intelligence. And even the boy who cried "wolf" in the infamous Aesop's fable was ultimately and completely correct--just before the wolf ate him. The world is a tough place for petulant children.

I Agree!

How would you know what "most" think?
