I have no complaints about the transmission. It feels about the same as my 6 speed Acura when both are in Sport mode. In Drive, I felt the shifts a little more in the Acura, AFTER they did a firmware update. I had never complained about the trans, but my Acura service rep would call me the day any TSB was released and ask me when I wanted to stop by.

Whatever some were complaining about must have been real though. Acura insisted on a transmission flush (free of course) at the time the firmware was updated. I think I only had 3000 miles on mine.

My mistake... jacko has the V6! And he is happy with it.

Also by no means do I want to down play anyone's issues. I am sure some of these will need repair but everyone keeps talk recall which is goofy. There will be a TSB some day on this once enough people have been to the dealer.

Glad you mentioned the flush though.... might be interesting if they need to change the fluid in some of the V6 8 speeds....

On the diesels.... will let you know when it arrives. The ML320 had a pretty solid (firm) downshift to 2nd but it loosened up right after my first tranny service. I don't think this is the case with yours Bretto thought that shift may smooth out a little with time.... how many k?

Was hoping it smoothed out when it clocked up some miles or learnt my driving but alas not yet. 2800 kms to date (1739 miles)


I'm thinking I might take a blat in a demo when they finally get one in diesel to see if I can feel the same thing.

Ya, it certainly will drag more in a downshift that a petrol engine but comparing with a lot vehicle is a very good idea.

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

I had the clunk while shifting from 1 to 2. 1-2-3 shift is rough when I try to accelerate gently if I rev it up it shifts fine.

3-2-1 downshift is little rough feels like it shift early and got a small jerk to the front. I want to make a point here, my other car has ZF 8 speed transmission bmw 3 series and it shows a very similar behavior when downshifting. So the downshift roughness can be a characteristic of this transmission.

You make a very good point. The Tranny shifts FAST, I mean faster than almost any tranny out there. Good thing is it means less wear, however it also means more perception in the down shift.

I think the 1-2-3 is better if you turn eco off, it shifts the points up slightly higher.

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

It has to shift faster, it has more gears to get through. Going 0 to 60, or 60 to 0 it has to shift seven times to get through all the gears, unless it skips a couple.

as for me:
2014 GJC Limited 3.6l
Hi. I got my GC Loredo 3.6L about 5 weeks ago. I have about 1100 miles, and my trans is also doing the hurky-jerky...I have a service appt. for Sat. I will report back after my appt. I'm going to print out this thread and show it to dealer. I'm sure I'm not the only GC buyer from this dealer, so I'm betting they've had some other complaints about this issue. I don't see how they can keep playing dumb about this.

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

Did you do the battery pull? It smoothed mine out.

Also, they're not playing dumb. If it's a software issue, which it likely is, there is no solution for this YET.

Dealers do not solve problems, they get answers/solutions from corporate and implement them.

Your dealership won't rewrite software to fix your transmission.

I think this may be part of the issue because it seems the tranny does not skip gears when downshifting in some instances.

Example: For some reason the tranny seems to downshift into each gear instead of skipping a couple when braking fast. A trannsmission should be intelligent enough to determine what gear is needed at a certain speed...even when deaccerating or while braking.

Have you read through these threads about the tranny issues? Well I have. And people are complaining that their dealer's service depts. are treating them as if there is no issue. And I'm sure their are enough complaints for their service depts. to know there is a problem. Software or otherwise.


Dealers do not solve problems, they get answers/solutions from corporate and implement them.


When I say dealer, I don't mean the person who sold the car, I'm talking about their service depts., you know, the people who fix the cars. I just assumed readers would get that and I didn't have to spell it out.


Your dealership won't rewrite software to fix your transmission


And how do you know it's not a mechanical issue?

Have you looked at my GC? There was previous poster who's tranny got water mixed with his tranny fluid. A mechanical issue. If people don't get it checked out, then how are they to know whether it's software or mechanical.


I realize I'm new here, and I'm no mechanic, but you don't have to get snotty about it.

Regardless of comments about the dealer can not fix or reprogram your transmission it is good to get these problems on the record early by bringing it to the dealer. This should have been fixed prior to production.

Reprogramming or other fixes need to happen soon before the GC gets a bad reputation which hurts sales in the long run. They need to get this message soon imo.
