2014 Grand Cherokee Overland Transmission problems
 
Hello.. Wondering if anyone else has had aggressive downshift clunking with the new ZF transmission? Taken to dealer twice and they dont do anything. :mad: Should I disconnect the battery to reset ?

Read this thread. I would pull the tranny fuse to reset.

Wrong forum. This is for the Cherokee, not the GC.

Hello Eagleone,

I have a 2014 GC Laredo with similar issues. Shifts hard enough to feel it in the brake pedal when stopping. Also had it actually lunge forward in park when pushing ignition on or off or taking my foot off the brake. Started acting up at 5,000 miles. Clunks and bumps shifting between P, R and D. Been to the dealer, they couldn't find anything, going back again next week. Plus U-connect won't remember my phone, "no fix at present." Very frustrated, I haven't even made a payment on the vehicle yet. Traded in a Ford Escape that had a broken valve spring 7,000 miles over warranty. Glad I bought the warranty that provides a rental car. Will take it in weekly if necessary until something gets fixed.

Hi All, I am having the same problem with my 2014 GC Summit, it barely has 3k miles and ran like a charm for the first month or so. I took it in earlier this week and was told an update "should" fix it. Well the problem persists, it shifts extremely hard going both way up and down shifting, in sport and drive mode, however it runs better in manual. I was told that the problem would not go away until some new software was approved by the EPA...sounds like a load to me...any suggestions? I do not want to keep driving it like this, feel that more damage will be done in the long run. Thanks all.

no, actually, any shift reprograms have to get govt approval in the US.. that part is not a load. this is to keep companies from getting EPA approval on an completely undriveable car and then 'fixing' it later.

I have a V8, so my experience won't directly map.

But.

Shifts (particularly downshifts) will be harsh in Sport mode, because the transmission aggressively heads for lower gears, sometimes when you don't expect it.

Might be useful to reset the PCM and then drive it like you want to drive it. Don't change modes, don't mess with the paddles, just drive it like you want to drive it.

Hi Tom, thanks for that

I also have the V8, the issue actually occurs most in D when the car is upshifting. I will have a chat with them about a reset and hope that does the trick.

Thank you.

Ping me after a few weeks if things aren't looking better.

Back into the shop again at a different dealer this time with my 2014 GC Laredo. Told me they did a "transmission update", but the paperwork states "flashed TCM up to date". So they didn't actually do or find anything. Still shifting very rough, probably causing damage over the long run. For whatever it's worth, this issue isn't unique to Jeep. I drove a 4 cyl. Dodge Avenger for my loaner and it was having similar issues with rough shifting.

Be sure to keep all paperwork in case you need it in the future.
