Dropping from 8th to 6th doesn't make it harder to get speed, it makes it easier to get speed. You seem to have it stuck in your head that a higher gear means more acceleration, it doesn't. Dropping down gears brings your revs up allowing you to accelerate more than staying in 8th does. You just have to keep putting the foot down and stop backing off because you think its doing the wrong thing.

Been there with keeping foot down on gas pedal but not translate into speed on big uphill...revs and fuel consumption up and up with gas pedal down and down, the only thing difficult to get up is SPEED, in particular on steep uphill. On light uphill, e.g, the one i mentioned in 80kph zone, after PCM update, the car can hold or increase speed when pressing gas pedal, so im ok with that.

In addition, how do you explain experience i had before TCM muck up: 1) speed limit on Mt Ousley Rd is 80kph. My speed was 80kph at 8th gear before climbing, i pressed gas pedal to keep speed at 80kph during the entire duration of climbing yet gear NEVER drop from 8th. Actually i had to ease back gas pedal to prevent over the speed limit. The same experience when climbing hills in Bulli, speed 60kph with 6 gear before climbing and keep it during climbing, and if i press harder, speed would increase to 70kph with 7th gear.

Another note, on mt ousley rd, i could only push speed up to somewhere between 50-60kph before PCM update, and can push up now (at best) to around 75kph after PCM update.

Thanks for telling us your story of your car working as it's designed mmcrh.

It's a perception issue mate.

Perception! Did i hallucinate while driving on Mt Ousley or Bulli? As designed because it cant not deliver speed? What type of 'Jeep Design' is that!

IF what you said is true, it would follow that the car i have before the TCM flash was not as designed because it could deliver speed promptly on any terrain as commanded.

You see this is where your info is confusing, because on one hand you say you are flooring it, then on the other hand you say you are trying to balance and trying not to let it change down. That to me is a bizarre thing to do, let it change down.

Your description of pre-TCM update makes zero sense to me, it certainly doesn't sound like a properly working car. You described it as uphill 80kph, 8th gear, revs going up to 3000rpm. That sounds like a broken car. 8th gear and 3000rpm is almost 200kph, if you are only doing 80 with that gear and revs, the car was broken pre-TCM. But I am so confused by the info you have provided, I don't know if that is really what has happened. I'm expecting the car actually was changing back to 6th, and you mistakenly thought it was still in 8th. Thats the only thing that adds up.

And the same for your description of Bulli, what you are describing is a transmission that wasn't working properly, if the info you are giving is correct. In 6th at 60kph, going uphill the trans should be downshifting. 1500rpm isn't enough to get you up a steep hill, it should be going back to 4th and bringing revs up.

So all your descriptions of what you thought was a working car pre TCM update, actually sound like an awfully broken car, or that you don't have a good recollection of what the gears, revs and speed were doing.

I'm not saying your car didn't have a problem, I'm just struggling with the bizarre info you've provided.

No way in the world your Jeep maintained 8th gear at 80kph going up Mt Ousley. Doing a 120kph...maybe...150kph....most likely.

I drove mine this morning thinking about your alleged problems. (to Tempe from Bargo - Ikea trip, had a hankering for some Swedish meatballs).

On flat road doing in 8th at 80kph, even if I apply the slightest pressure to the accelerator it kicks back to 7th.

115kph in 8th it kicked back to 7th with the slightest increase in pressure on the accelerator.

When travelling to Mittagong up Catherine hill I set the cruise control to 120kph and it will hold 8th with just me and my son in the car. Add the wife (60kgs) and daughter (40kgs), it will drop back to 7th to maintain the 120kph.

If your saying that you cannot maintain a speed of 80kph up Mt Ousley than your car does have problems and sounds more like a engine problem.

Sure it's not in limp mode, with a DPF full???

Seriously if you want to drive to Bargo one Sunday arvo we can compare our vehicles. But from what you have described sounds like mine is the same.

Re: 2014 Grand Cherokee information - Australia

Snuke's picture tells all......LOL!

First of all, thank u all for taking time providing inputs, and apology for causing confusion.

Lets set aside what speed at what gear and at what rpm, and simplify the issue at hand. When a driver pushes gas pedal, s(h)e wants to either maintain or increase speed and a car shall respond promptly. Its as simply as that. I don't think everyone would dispute this.

Reading members' comments along with my research on google regarding electronic throttle control, I would concur wholeheartedly that pressing gas pedal triggers gear downshift and increase in rpm which lead to INCREASE IN SPEED. Bigskiddy kindly proved that with his driving.

In my case, before TCM flash, i pressed gas pedal and the car responded with increase in speed promptly regardless of terrain. After TCM flash, when i pressed gas pedal, gear did drop, rpm did go up, and 1) on flat Rd or light/moderate uphill, e.g, on motorway either merging or overtaking, it struggled to increase speed promptly compared to pre-TCM flash; 2) on big uphill, e,g, mt ousley, i could only push speed up to somewhere between 50-60kph, fall short of wanted speed of 80kph. It begs the question why increase in rpm and drop in gear does not translate into increase in speed? Where is the missing link?

After PCM update, i feel immediate improvement regarding increase in speed: on point 1) even though the speed increase is not as prompt as pre-TCM flash, I'm happy; 2) on point 2) above, i can only push speed up to 75kph, not happy jane. IF why the PCM update makes the car tick can be answered, then a solution to my problem would be on the horizon....

What's it like doing 0-100kph? Time it and see how it compares to the stated.

If you can't get it to reach 80kph regardless of which gear your in, there is a serious problem.
I can do 100kph up Mt Ousley pulling a 2 tonne caravan.

Re: 2014 Grand Cherokee information - Australia

MMCRH - I don't understand your reticence about allowing your fellow JG members to help.

They have requested a video showing what you say is happening.

You say you cannot provide that.

A couple of times it has been suggested that you meet up with someone that is willing to drive it with you and compare vehicles.

BigSkiddy has just made that offer again this afternoon.

You have not acknowledged that offer.

It doesn't matter how many posts or explanations of revs or kph's or declines or inclines or whatever you post, the written word on a forum is no substitute for the real experience.

If I were you and experiencing what you say you are and I truely thought that this was an issue that Jeep Aust did not have a handle on, then I would be champing at the bit to meet up with other GC owners who could substantiate my claims.

I don't understand why you seem (to me) to be blowing the guys off when very real offers of help have been made.

Re: 2014 Grand Cherokee information - Australia

Oops, my oversight. Appreciate Bigskiddy's offer. Thanks Mate. Will keep your offer on my radar for the time being.

Jeep Aus has the full car scan report and the dealer awaiting their response. Hopefully the service guy can provide me progress update next week If Jeep's response is 'it appears to be normal', i will request the service tech to drive up big hill in person. Experiencing is believing.

Any idea on possible culprits as to why it only occurs on big hill?
