I remember the days when if you had a problem with a radio, you brought it in and said "listen" to my radio. Those days are gone.

Good luck today.

Re: I Think I Fixed My Rough Shifting 8sp Transmission

Well funny thing 5 minutes in. I printed off the TSB for the transmission and it had the 3.7L. The service manager comes out and says that it doesn't pertain to my vehicle. I tell him that it does and I will show him the TSB on it (granted he didn't look at the TSB long enough that it says Grand Cherokee on it). So I go to wk2jeeps.com and show him the TSB with the updated 3.6l instead of the 3.7l. He writes it down and says they will look into it. I also gave him the Star Case for the radio. I don't think he completely understands what is needed to be looked at here..We shall see what happens in the next hour or so.

Re: I Think I Fixed My Rough Shifting 8sp Transmission

Update: They didn't do anything to my transmissions as they didn't even know about the TSB on it. They said without the software on it, there was nothing they could do at this point. So they want me to call back in about a week.

You can do the Radio update yourself to 13.19, don't need a dealer for that.

Re: I Think I Fixed My Rough Shifting 8sp Transmission

I plan to go into the dealer in the next week or so. For those that the dealer is saying they do not have it, I would challenge them.

They should be able to logon to their systems with Chrysler and get these updates.

I was in last week to have a number of items addressed and he tried convincing me the Uconnect version I had (13.10) was the latest. After telling him that is wrong, he went back into their system and came back 20 min later and figured it out.

All of these updates should be available, it is a matter of having them look for them.

Best of luck

SUBJECT: Flash: Transmission Shift Enhancements

SYMPTOM/CONDITION:
i. Harsh second gear to first gear/first gear to second gear shifts while using the paddle shifter when the vehicle is not moving.
ii. Inconsistent and/or harsh upshift quality during light throttle/low speed upshifts.
iii. Inconsistent and/or harsh downshifting quality while coasting down.

REPAIR: Reprogram the TCM with the latest software

thanks Milhouse for the great info..going to the dealership today for a discussion...a5t least my tech knows that the 8-speed is a little clunky (his words) and he was expecting an update soon...he will be glad that they got it figured out...as well about a 1000 or so of us too. Great info

thanks again..Ron
