11k miles and blown Transmission

I was driving in the city today doing 35mph when my "check engine light" illuminated and made a "ping" notification sound. I thought that was odd so I pulled over, put the car in park, and turned her off and back on again. Same issue. I called my dealer and scheduled to drop the Jeep off tomorrow morning and let them have it till friday afternoon (leaving for work anyway).

I merged onto the highway to go home and tried to accelerate. I heard a very disgruntled engine noise and my RPM's redlined. The vehicle would not go more than 35-40mph and no higher than 4th gear. Multiple attempts to downshift and fix it with no resolve. I ended up slowly limping off of the highway and noticed that as I was pulling into the parking lot I was in 4th gear at around 6mph.

Ended up having to get it towed to the dealership. Service advisor said it might be the computer or they may need to replace the entire transmission on it.

2014 Jeep Grand Cherokee Limited. 11,770 miles. Purchased October 2013.

I think this might be my final straw with Jeep. I might have drawn the short straw with my vehicle as I dont think anyone has had as many problems with theirs as I have. However, for the amount this vehicle costs it just doesnt seem worth it anymore.

Re: 11k miles and blown Transmission

Let me take a wild guess....v6 right? man this is not good. my q's is why did Chrysler even have to touch the 8spd? I've heard because of torque reasons. this doesn't even make since to me since the v8 and diesel(most torque) are directly bolted on w/out even a touch of a finger of an engineer from Chrysler. I don't get it.....

I hear yea.....how do they screw it up. I understand some revised software algorithms may need remapped, but damn touch the internals of a perfectly well built german 8spd and f it up. is their anybody with a 14' that has had their gc for at least a year that hasn't been to the dealer for warranty work? (not including tsb,or reflashes,etc)

I guess I'm one of the lucky ones. I haven't had to bring mine into the dealership for warranty work.

Re: 11k miles and blown Transmission

Yep...stories like this just further confirm that the V6 transmissions have issues, and Chrysler doesn't know how to fix it.

This is my second 2014 GC V6 which has had transmission issues...at about 5,000 miles I started to get the dreaded hard downshift into 1st with my current Overland.

That's why I decided to forgo purchasing an extended warranty, and just get rid of this vehicle before the warranty expires. Then it's "Hasta la Vista" Jeep forever.

It doesn't confirm anything yet. At least wait until they diagnose it before you throw fuel on the fire.

I'm not saying it's not the transmission, but it could just as easily be a module that is external to the transmission.

If it turns out to be the tranny, have a field day. We all know you don't like it, with good reason.


BTW - just wondering if you are keeping track of the number of 'anti tranny' posts you have made. I'm not suggesting you should slow down as it is a good outlet for your frustration ... much better than kicking the dog. But if you would number them, it would be easier for those doing research to distinguish the difference between the number of negative posts and the number of actual problems.

Re: 11k miles and blown Transmission

Do know the trans used with a 6 is lighter duty than the one for the Hemi or Diesel but something is bothering me. With a 1.6:1 4th you should get close to 70 mph at 4000 rpm, so it may say "4th" but sounds more like 2nd which may be the issue.

Will say that the 5 speed in my '12 has been used by Merc since the last century and is pleanty to tow a 3500 lb trailer. Somehow the need for an 8 speed with a flat torque curve from 2000-6300 rpm excapes me.

Re: 11k miles and blown Transmission

I guess I lead a charmed life. I have an early build (April '13), and have had no problems at all with the tranny. I haven't had any of the software updates done for the tranny, and only the instrument cluster tsb and an oil change done. Still need to get the brake booster recall done. I drive city, highway, and a little off road (no rock crawling), and it's been as smooth as silk.

How many reflashes has Chrysler/Jeep put out for the 2014 transmissions...over three...and they STILL haven't solved the rough shifting problem.

I post the good and bad when it comes to my Jeeps...as for the bad, I only post about issues I've personally had with my 2014 GCs, repeatly yes, but I don't post just to bitch.
