Re: If your 8spd trans is rough, put your hand up

I have the 2014 Overland V6 with 8300 miles. I began to notice that the transmission was jerking when slowing to a stop at around 5000 miles, especially when it downshifted into first gear. I read on CarComplaints.com that someone referenced bulletin" 21-012014 Rev. dated July 9, 2014. He had his Jeep updated in November and it appears to have solved his transmission problems. I am having my Jeep checked by the dealer this week and will let you know how it turns out.

Re: If your 8spd trans is rough, put your hand up

I had the latest TSB applied and it actually got worse. We are heading out on vacation today and we are gone for a week, so we dropped the Jeep off for more work. The owner of the dealership and the lead service guy said there are "definitely some tweaks they can make" to help me out, so I'm hopeful they identify and fix the problem.

Coincidentally the last two TSBs applied for me were also done with quick relearns. Both times the shifting deteriorated quickly to the worst it's ever been. I did the battery disconnect about 2 1/2 weeks ago and shifting has been consistently good.

It sounds like your original "relearn" was the teenage equivalent of "studying".

Perhaps the reset you did was a little more like going to the library instead of "studying anatomy" at the drive in.

Yes, I'm that old...

Re: If your 8spd trans is rough, put your hand up

I had the TSB done on my car a few weeks ago and boy was that a bad decision. The jump from 1-2 has gotten worse and now it seems I have a 5-4 bump. I'm going to call the service dept to have it looked at along with the RA4 (service phone, reboots)

Just curious if that TSB they performed included the quick relearn procedure. The shifting on mine went to total crap afterwards. After the second quick relearn the service guy said I would notice some harsh shifting as the transmission adjusted. I put up with it for a week and couldn't take the very hard shifting any longer so I rebooted the vehicle by disconnecting the battery. Made a huge difference. Keep us posted on the post service visit.

Re: If your 8spd trans is rough, put your hand up

With my most recent reflash (4th), the dealership supposedly did a "full-relearn" according to the work order...didn't do a damn thing. I was getting the usual rough downshift from 2nd to 1st crawling in rt. 93 traffic right after I picked it up from the dealership.

I submitted my paperwork to a Lemon law attorney the other day...I'll keep everyone informed.

Re: If your 8spd trans is rough, put your hand up

I gave up on my Grand Cherokee, the transmission must be faulty by design, I have no other explanation, otherwise Fiat/Jeep/Chrysler would have fixed it by now with all these TSB's.
It's the worst automatic transmission-engine combination I ever had, sure you can deactivate Eco, put in Sports, use paddle shifters but to be honest who does that on a constant basis?

I can't understand why they can't get it to shift like the Ram 1500. I drove one with the Hemi and 8 speed combo and it was flawless. Not a single rough shift up or down. It was kind of a weird sensation actually, my mind was so used to the 6-5 clunk that when it didn't happen it really caught my attention. I'm baffled as to why the programming for the Grand Cherokee is so far off.
