Re: Awful shift points. Will we ever be able to do anything about it?

You know, I can't say that my Jeep ever is at 1000rpm while under load. Coasting or idling sure, but I'm pretty sure it downshifts before 1000rpm.

Re: Awful shift points. Will we ever be able to do anything about it?

Well it was close to it whatever it was. Hopefully I didn't make it sound worse than it is, it just seems that in some situations the tranny should be shifting at better points. And like mentioned above these better shift pouts IMO would be more beneficial for economy reasons. I agree with what was said above, how could bogging the engine up an incline, then have to push the accelerator more to get it to downshift be good fr economy? If it would have just stayed in the original gear to begin with would have been perfect (just as an example).

Re: Awful shift points. Will we ever be able to do anything about it?

I agree with you guys 100%. I love our new 2012 V-6 Grand Cherokee but, I am worried that the dead spot in the shifting is going to cause a safety issue for the wife when she is driving it in traffic. I notice it especially when I am moving at a slow rate of speed and try to accelerate and nothing happens. Sometimes you need that shot of power NOW to slip into a gap in traffic or get across and intersection. The delay created throws the timing off and will no doubt cause issues if not remedied in short order.
It is better in sport mode around town but, once on the highway mine doesn't seem to want to go into fifth when I have it in sport mode.

Re: Awful shift points. Will we ever be able to do anything about it?

I suspect part of the problem is that the torque of the v6 is produced fairly high up in the rev range and to get a couple of ton mobile to get in a gap in traffic or whatever, the poor little v6 needs revs, and when it gets over 2000 or so you can really hear it working, mine sounds quite harsh over a couple of thousand revs, funnily enough mine climbs hills ok once it gets in its torque band.Maybe we will get a transmission shift update before too many people get pissed off.But as i said before it is definitely better than it was before, the adaptive learning is happening or i just compensate more with the throttle. My shit box standard work Falcon ute is better at deciding what gear to use, just sit back and go with the traffic and not give it a thought.

Could you elaborate on this further? And does this happen immediately after the transmission shifts, or...?

I'm hoping to buy a V6 when the 2013s come out, but if that sort of transmission / other behavior -- which I agree could potentially be a safety hazard -- is normal and unfixable for this transmission via a software update, then that makes me a little wary.

I do not notice a difference in sport mode. Tow/haul mode makes a big difference though. I have got in the habit of hitting the tow/haul button every time I drive it.

I just wish the tranny shifted normal without tow/haul on. My hemi gets to 4th gear and just kinda stays there. If I come up to a hill, it lugs down until I either hit the gas and force a downshift or it finally decides to do it on it's own. Both situations cause for a very jerky downshift followed by everyone and everything in the jeep being thrown to the rear of the vehicle.

My uncles, dad, and brother are all Ford guys and I get to hear that "My Ford doesn't do this..." everytime it happens. It's quite annoying.

I do think this is my first and last Dodge/Jeep for a daily driver though. The vehicle is very nice but it's the little things that are annoying as hell when driving it.

Re: Awful shift points. Will we ever be able to do anything about it?

I used to notice it most when exituing a slow speed turn. I would go to accelerate and there was a dead spot in acceleration. As you slowly push the gas pedal down nothing happens. You have to jab the throttle to the floor (or use the gear shift) to force a transmission shift or you basically are moving at 20 mph in 4th or 5th gear with zero throttle response if you don't. Trying to merge into traffic is a crapshoot without immediate throttle response and unfortunately, it's just not there right now unless done manually. I have high hopes Jeep can get this fixed.

Re: Awful shift points. Will we ever be able to do anything about it?

@Frostbite, interesting, as that sounds kind of similar to what's reported as being fixed in the following TSB: Attention WK2 3.6L owners - New TSB for Shudder, harsh shifts, performance and more!

Apparently (and unfortunately) though that only applies to 2011s built before December 20th, 2010.

Does it happen all the time? Also, have you complained to Jeep about it?

Re: Awful shift points. Will we ever be able to do anything about it?

Yes, it does happen all the time unless I turn it to Sport Mode. Once in Sport Mode, I seem to lose 5th gear on the highway. It forces me to jump back and forth from Auto to Sport. Not good! I can muddle my way through the shifting by doing that but, my poor wife would just put it in Auto and do her best to drive. That's where my fears come from.

I think it's something with the six speed trannys. My Jeep and BMW shift the same way, punch it wait a half second them Bam!! as you say.
I noticed that once up and moving I put the Jeep shifter into manual mode and shift it to 5 and leave it there. Little smoother shifts and it seems a little more reponsive.
On the highway fif I'm going to for a long ride I move it to 6..never D..
Try it see if you like it.
I also think this shuts down the ECO mode orr MDS.
