Re: New TSB - MAJOR shift enhancements/improvements 08/27/14

I'm going in for this next week as I literally, just this morning, started experiencing the "2 - 1 downshift rear-ending sensation" for the first time in 8000+ miles. "Bump" is too euphemistic a term: the entire vehicle lurches forward. This can't be good for the mounts or transmission. It does it every time... it went from "never" to "always" with a flick of a switch. That definitely seems like a software problem to me.

Glad there's a flash, even though it was only released two days ago and I wonder what would have happened if I had this crop up a month ago.

I got the day it released. All fishbites, shudder, and thumps are gone. It does bump on downshift when deceling but in a manner you would expect. Very smooth. There seems to be less lugging in ECO mode as well. The difference between Sport and ECO is not as drastic at partial throttle.

Re: New TSB - MAJOR shift enhancements/improvements 08/27/14

I only picked my new JGC last week a day before this release. Is this update added as part of the normal scheduled servicing or would it be on request only?

I haven't experienced any issues as yet so would you guys advise that I attend the dealership proactively to have this update applied.

Typically TSBs are only applied upon request.

Typically, yes... unless they also happen to be tagged as a rapid response transmittal (RRT).

This particular one isn't.

Theres the key words you used "haven't experienced issues"....you need to have a symptom to qualify for the cure because its warranty work. If you want the TSB, tell them it shifts rough while slowing down.

It's probably the truth, too, even if they haven't noticed it because it was just presumed to be "normal". People can say this with a straight face and clear conscience even if they haven't noticed anything "out of the ordinary".

Besides, there's a definite Jekyll and Hyde persona to this transmission. You want that fixed before Hyde suddenly crops up one day and literally starts jerking the whole vehicle around.

Awesome! Since last time I mentioned the horrible "jerking" at slow down they said they could not recreate it. So I'll be going in for this TSB soon.
