Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

Well took it back to the Dealer this morning and after 1.5 hr they re-flashed it and suggested that it was the eco mode and I should not use eco mode except when I am driving on the highway.

In all fairness they are at a big loss as to what could be causing this and are pulling at straws.

They also did my oil change, and I will have to watch how long this one last.

I must say that the Dealer (Airport Jeep) has been very responsive.
That is a far cry from where I purchased my Jeep (Central Florida Jeep) who lied to me and did not do any work when I brought it in.

I will have to wait to see how it reacts tomorrow and hope for the best.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

I'd like to change my position on this latest transmission reflash from Chrysler...the tranny nows shifts like it used to, PLUS it now sticks in first and hunts for a gear a bit after a cold start.




I'm going to disconnect the negative post of the battery to see if that helps.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

Does this look like the 2nd Transmission TSB (Issued in Sept with Aug 12 Build date) was applied correctly?

How do you know for sure?

I am having the same transmission problem with my 2014 JGC SRT, even if it's a 6.4 engine it has the same issues. Do any of you guys know anything about this? Is there a TBS for my Jeep?

Thanks

There has been almost 0 complaints about the HP70 Transmission in the SRT/Diesel/V8. If you have clunkiness, you need to see your dealer.

And that one is build by ZF as opposed to Chrysler.

Curious. How does it run with ECO Mode off?

This crap about who built it is a joke.

When ECO mode is off, is it now suddenly a ZF transmission and with ECO mode on it's a Chrysler. Because the TRANSMISSION is great when ECO mode is off for most people (that complain at all).

The transmissions are mechanically fine, who ever built them.

I had my car in Non ECO mode this morning and it was running like a champ.

Also noticed from a stop it shifts up damn nearly as fast. Almost too fast to even measure accurately. You can also feel it before the display even updates to the next gear.

It's what they are telling the Engine to do in ECO mode that is causing most problems.

My biggest complaint is they don't allow the owner to default ECO mode off. There is absolutely no reason they can't offer this.

ECO mode does indeed get amazing MPG. My suburban commute the other day I got 32 MPG in ECO mode. I got around 22 with it off. So I sure would like to leave it on. But perhaps you just can't have it both ways. It sure feels like it could. Like if you quickly stomp on it, automatically switch to non ECO mode, then after cruising switch back to ECO mode.

Actually, I never use ECO mode because I forget, I just got my vehicle 2 weeks ago. The clunk I hear is from speed 1 to speed 2 or when I accelerate and then release the gas pedal and then accelerate again (clunk!).

It really sounds like there are two problems.

The Lagging/Stuck in Gear/Over Downshifting in ECO mode (definitely software because ECO mode off this reduces 98% for most people).

Clunking.

I've never had a single clunk in any mode. But it is frequently reported.

I wonder if the clunking is a mechanical issue?

All issues could be what the adaptive system has learned by individual drivers. Not that it's right. But could explain a lot of variability in opinions.
