Range Rover Evoque 6 Speed Auto Gearbox Judder - Fixed

So I thought I'd post a thread describing the problem I had with the gearbox on my car and also the solution that has fixed the fault without having to take the gearbox apart.

Once the car had been driven for a while and the gearbox was up to operating temp, the car had a very noticeable judder or lurch when moving away from standstill, typically when taking your foot off the brake to move forward when stuck in a traffic jam or at a junction. The only way to avoid it was to select N and then D before moving away. It wouldn't happen immediately or on every journey but if you got stuck in traffic after about 30 min it would.

I spoke to many gearbox specialists and they all suggested booking the car in for diagnosis and most likely at best a valve body replacement (circa ÂŁ1k) or at worst a full rebuild (circa ÂŁ3-4k). The car had only 65k miles and had already had a gearbox fluid change in the past 10k miles so I kind of ruled out a further gearbox oil flush as being of any real use.

I was given very generic advice that if the transmission is problematic when cold (judder/mechanical noise/unable to select gear/falls out of gear etc.) then it will most likely need a rebuild of sorts. But if the gearbox behaves when cold and the problem arises once up to temp then it's likely it could be fixed with a valve body replacement. Of course, you should always check for fault codes first and in my case I was getting some gearbox related codes and the problem persisted only when the car was up to temp, or more specifically, the gearbox oil was up to temp, which is impossible to determine without diagnostic equipment.

I was literally about to book in for a suspected valve body replacement when I found this document on a different Evoque thread............

Admittedly, this was for the North American market but the Condition Summary described my exact problem:
  • A rough gear change or 'jerk' when releasing the foot brake from a stationary position while the vehicle is in DRIVE(D) (handbrake not applied). For example, in a traffic jam or pulling away from traffic lights.
Clearly, it made sense to try a software update before ripping the gearbox apart so I booked it in at my local main dealer (Harwoods Land Rover) and requested this update be applied to my car. They found a corresponding Technical Bulletin for the UK market on the system that had been issued around the same time and attempted to install it.

Unfortunately, the car wouldn't take the update but the technician was confident he could make some changes to the Power module and some adaption changes that would have the same effect.

Well, almost 2 months later and the car has been perfect ever since. I have driven well over 2k miles in that time including many long journeys over 1 1/2 hrs when the car would normally play up so I can safely say the problem has been fixed. And I was charged only 1 hour's labour by the main dealer.

A big thanks to Harwoods garage in Pulborough for their expertise and for saving me at least ÂŁ1k in repair costs that would most likely have not solved the problem. For anyone else with this issue or similar, try a visit to the dealer before going down the gearbox rebuild route.

For the record my Evoque is a 2013 2.2 SD4 with the Asin 6 speed automatic and 65k miles.

Mine does exactly this - long journeys its fine. Traffic jams, and there's a 'jerk' when in 'D' and letting foot off the brake. Did u just contact your local JLR Dealership and quote the service bulletin?

I do the reset and then it's fine again for a little while. only had 2 weeks and deciding if I should take it back or not. lots of people here say it's ok to keep resetting it. happy with it otherwise
Yes, I went into my local dealer and had a chat with one of the service technicians. If you quote the Technical Bulletin number listed above they'll be able to find the UK equivalent on the system.

Like I said, they weren't able to install the update on my car but the senior technician clearly knew enough to be able to make the changes required. Perhaps, he was able to study the software update intended and note the changes that update would make to the various control modules and then apply those changes manually?

I don't think this issue is particular to the Asin 6 speed as a friend has the exact same problem with his 2018 Evoque with the ZF 9 speed. I'd suggest you try your local main dealer and see if they can install the update or make the necessary changes as required.

Off the back of your thorough post, I've contacted a couple of local specialist service centres asking for advice, quoting that US tech bulletin and I'm awaiting replies. 1 already said they couldn't do it, but it was more of a general place. I've also contacted my local Land Rover Service Centre (official from JLR website, not sales just servicing) so I'm waiting to hear back from them - my mate uses them and says they are brilliant.

I've got 12 days before under the 28 day rule I could return to the car dealer if I'm that concerned - plus the 3 month warranty. Just a bit nervous about any future massive bills if there's anything else underlying. thanks again @-AJC-
Yes probably best to stick to the main dealers on this one - hopefully your's has good coffee and plenty of free pastries? ;)

Hi this is the exact same issue I have, great post, would you know if any other Land Rover dealers can do this or do you have the technicians name in Pulborough as would happily drive the 3 hours to get this fixed, what did they charge you ? Many thanks John.
John, I see no reason why another main dealer couldn't make the same changes to your car. You may even find that your car accepts the original software update?
Harwoods were really good with me and only charged me for 1/2 hr of labour. If you like I can pop in there later this week and ask exactly what was done or who you should speak to. Again, can't see why their technician can't explain to another dealership exactly what he did to save you the drive? Leave it with me and I'll try and get more info. Where about's are you based and do you know the name of your local main dealer?

I'm looking forward to what my service centre can do, it seems your post has rung a lot of bells with fellow owners and given them hope for a fix
I think it's fair to say that in many cases these issues can indeed be fixed by software changes rather than anything mechanical and the proof is there in black and white. Even at ÂŁ225ph plus VAT this is good value!

Gooey36 had posted in the past that he had the same issue fixed by software update but not sure he's still on this forum? The purpose of the thread was simply to highlight to other owners experiencing the same issues that these can often be fixed with a relatively inexpensive software update rather than a costly rebuild and should be the first thing to do if you have the same issue.

Here's a PDF Copy of the technical bullet I found online (after @-AJC- original post) - I took this into my JLR Service Centre, he read it and looked up on his computer and said he found it. So it must be in their systems, maybe a different reference/description. When he booked me in, he wrote the fault and the bulletin number on the job sheet. When I go in, I'm taking a print out again - just to make sure
Yes this is exactly what I did. Visit in person, get the service team to look up that Technical Bulletin number on the JLR database and it should correspond to an identical bulletin released for the UK market. Then simply book the car in to have that update applied.

Hi Graig who worked on your car is going to call me tomorrow so will let you know if he’s able to fix my car, fingers crossed, a long drive but worth a shot,.
That's great. I'm sure he can make similar adaption changes to your car like he did to mine and as reported mine has not 'jerked' once since the changes were made.

Happy to report that some 6 months and 9k miles later, the gearbox has been faultless. I'm confident to say that this issue has been fixed by a software update to the TCM and did not require any mechanical intervention.
