Anyone experiencing a problem with the 4-5 downshift when shifting manually. Mine hesitates the revs pick and then the gears engage and you feel the braking effect. While all this is going on the car is free wheeling very disconcerting when going down hill the car can accelerate up to 5+ mph. Dealer acknowledges it doesn't seem right but so far no explanation. Issue now in Land Rovers hands. Want to understand if it is just my vehicle or do other have the same issue

My 2015 model with 2k miles has a jerky shift from 4th to 5th before engine and transmission reach normal operational temperature, typically 10 - 15 minutes of driving.

Happened to me yesterday while driving in automatic. It would stick around the 4/5th gear and rev to 5 rpm then drop to 1 rpm when the next gear kicks in cause the car to jerk as if its going to stall. The problem corrected itself when I shut the engine off and restarted. Got some other issues to that pop up and then resets when you turn the car off. I don't think I should be having problems when driving.

Local dealer dropped in the Q450 transmission software upgrade. Shifts smoother but still have the 5-4 engagement delay. Not happy

Got the Q450 letter in the mail a couple days ago. Can't say I've experienced the 5-4 delay but will be taking the Evo in for the remap today so we'll see what happens afterward.

Just had the Q450 update. Biggest change I've noticed so far is that it seems to downshift to (first?) when rolling up to a stop. Hadn't noticed that before.

After a few hundred miles, seems like the reprogram settles somewhere between S and D of the old program. Seems to be in the correct gear more often. e.g. when turning onto a side street, where it used to be in one gear too high causing a slightly jerky downshift, it now seems to be in the correct gear.

That's good news. Taking my 2015 Evoque to the dealership tomorrow to have this service action done. I was a bit surprised by the default transmission feel when I got the car after coming from a Infiniti FX50S. Hopefully this SA will make the driving experience more refined.

Sorry to hear these problems. My 2012 6 spd, is great! Paddle shifts as it should. Whenever I get a new "Loaner", when my car is with the dealer.....I can't wait to get it back! I hate the new trans. And what's with the "Clunk" when you come to a stop? Yeah I wish I had some of the updates, but they can keep that new trans.

I took the car to stealer and complained about jerky shifting from 4th to 5th. They did reprogram the tranny software "RECALL Q450". It did not fix the problem.

Drive mode is always 1-2 gears too high and car is reluctant to downshift, say when going around an intersection so of course, you roll deeper into gas then it drops 2-3 gears . Not exactly good for mileage or smoothness. Normal sport mode is just fine in normal drive mode but it is szchiophrenic in Dynamic mode. Going in for complete reprogram in May. ONLY issue I have with the car, too many gears and a tranny trying to be too smart.

My problem after the reprogramming is the transmission seems to stay in a high gear lugging around 1000 rpm. I can't tell what gear it is in because it only displays "D". It also shifts harder and delays when accelerating. I have an appointment this week with dealer whose service manager says he has had a number of complaints. Here is an excerpt from an article in Road and Track about the ZF 9 HP gear box in the Evoque:
Problems with the ZF-designed nine-speed automatic transmission are continuing to pile up, with customer complaints continuing to roll in regarding new Jeep, Chrysler, and Acura models.
A recent report from Automotive News said Fiat-Chrysler would be updating software for the transverse-mounted 9HP gearbox on 2014–2015 Jeep Cherokees and four-cylinder 2015 Chrysler 200s starting this month. This marks the third time the automaker has released a software patch (the last occurred in May) since the Cherokee’s debut in late 2013, which was delayed to fix problems with the transmission. The Cherokee and 2014 Range Rover Evoque were the first two cars in production with the nine-speed, followed by the 2015 Chrysler 200 and six-cylinder versions of the 2015 Acura TLX.
As of today, we counted a total of 145 unique owner complaints posted to the National Highway Traffic Safety Administration, 126 of which explicitly named the 2014 Cherokee’s transmission. Another 10 transmission complaints were lodged for the new 200, and eight have been posted to the TLX’s log file. There were no complaints recorded for the Evoque.
<img class="aligncenter size-large wp-image-150434" src="/wp-content/uploads/2014/05/2014-Jeep-Cherokee-Trailhawk-PLACEMENT-626x382.jpg" alt="Jeep Looks To Improve 9-Speed Shifting in Cherokee" width="626" height="382" />
But these allegations are far worse than the sluggish and delayed gearchanges we’ve experienced testing the Cherokee and Evoque (and yet absent in the 200 and TLX). Cherokee, 200, and TLX owners have each reported conditions such as sudden lunges from unexpected downshifts, a lack of kickdown upon entering highways, front-axle vibration in low gears, and complete failures in which the transmission shifts into neutral while driving and lights up the dash with warning lights. Other owners have reported rollaways in which the vehicle indicated it had engaged park when it was actually in neutral. One of these reported instances involved a Cherokee that went into a lake, having first rolled over someone’s foot and dragged the person into “eight to 10 feet of water,” according to one NHTSA complaint. In December, Honda recalled nearly 9400 Acura TLX sedans for this very problem.
While NHTSA has not launched an investigation, Jeep dealers are replacing between 12 to 15 transmissions a week, according to AN. Aside from Honda, there have been no recalls for this transmission, only lots of frustrated owners from these first-year vehicles.
“We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast,” FCA CEO Sergio Marchionne said at the Detroit auto show last month.
<img class="aligncenter size-large wp-image-167920" src="/wp-content/uploads/2014/09/2015-Acura-TLX-3.5L-FWD-PLACEMENT-626x382.jpg" alt="2015 Acura TLX 3.5L FWD" width="626" height="382" />
ZF told us the problems were entirely due to software and not to anything mechanical, but it would not comment on what specific improvements it was making, as “ZF works independently with each customer based on their needs.”
[HR][/HR]
[HR][/HR]While automakers each use specific programming and more—Jeep seems to rarely engage ninth while the Range Rover does do more often, and Acura determines its own ratios—there likely will need to be an overreaching update for all models. Based on 2014 sales alone, this gearbox is running in at least 320,000 cars in the U.S., likely more once cars sold late in 2013 and thus far in 2015 are accounted for. New vehicles slated to use the 9HP transmission that are scheduled to go on sale this year include the 2015 Land Rover Discovery Sport, 2015 Jeep Renegade, and 2016 Fiat 500X.

Great thread and just sent it to my service dept to give them a head's up!

This is my synopsis of a proper fix. (Dr. Gagne)
1. Don't let rpm go below 1800 without downshifting unless coasting. 4bangers get buzzy below this point. Not a great Range Rover NVH sensation.
2. Make TPS slightly less touchy so transmission isn't as easy to provoke into multigear downshifts when it was initially reluctant, but indeed, make sure programming is biased towards proper gear and less toward that extra .1mpg which i suspect is the biggest issue.
3. Biggest difference between drive and sport mode should be rpms at which upshifts occur.
4. Sport mode should be same regardless of dynamic mode being selected. If you're driving that aggressively, 90% of the time you'd be on the paddles anyway esp with suspension at its most sporty.

In conclusion, it seems the tranny works best at present when either driving like a little old lady or at the opposite extreme, when you're flogging it. It is lousy when driving smoothly and normally. BTW I have always gotten great mileage not by driving slowly but by being smooth--> something this tranny does not seem to reward. (Like Scott Dixon in Indycar!) See you in May, and if Land Rover wants to use me I'd be very happy to help as I'm a bit better than your Joe Average at calibrations.

Also I have no 4rth to 5 issues. Biggest complaint is why sport mode differs in regular suspension mode and dynamic suspension. Holding a gear once cruise is engaged, for example, is just poor programming. Tranny needs to recognize steady TPS state and steady speed.

I took the Evoque to the dealer and the shop foreman drove the car. It acted as I described above. He said he has numerous complaints but has no fix currently. I asked him to reprogram it to the original software, and he said he has no way of doing this. LR has not provided a way of returning to how the car was delivered. He said he would speak with LR for a solution. I told him that I would like to speak with the LR technical representative. I also sent a complaint to LR regarding the problem. I also told the shop foreman that using the manual mode is not a solution to the shifting problem.

Sounds like another guy that realizes the shifting issues are perpetuated by trying to squeeze out mpg's. Its a programming thing. They want an auto that just plain works, let them drive my wife's auto Miata. Not as sacrilege as you think because it does what its supposed to do. The intent of a 9 speed tranny is keeping motor in the sweet spot. problem is the sweet spot is smaller than what is efficient for the tranny to stay in. Parameters for a 2000rpm variance between gears is far different than a 200 rpm variance. I swear in drive it shifts every 2-300 rpms.

My 2015 model with 2k miles has a jerky shift from 4th to 5th before engine and transmission reach normal operational temperature, typically 10 - 15 minutes of driving.
Curious how you know what the shift point is? Are you shifting manually with the paddles? Or counting? Or have the speed/tach speeds memorized? I think the European models show what gear your in when driving in auto. I have a '12 Evoque which doesn't provide which gear I'm in unless I'm in SD. Even then, I have to use the paddles to see the current gear.

I'm considering getting one of the new Discovery Sports, but am uneasy with the 9 speed transmission in the eternal quest for higher mileage. One thing I don't like is constant shifting when going up hills, especially slight hills. Pi** on you EPA.

Just had the latest reprogram done and , finally, they got it right! Doesn't hang out below 1600 rpm anymore even in drive which was pathetic before. Doesn't drop 3 gears after refusing to downshift with moderate pedal application. It just works now.

New software did not help. shift from 4th 5th is still jerky when transmission is cold. Took it back to the dealer. Mechanic logged over 500 miles to our RR during a week long 'repair' and provided test results, including pressure measurements, to Land Rover. According to LR there is nothing wrong with the tranny. I picked up the car and the shift from 4th 5th is still jerky when transmission is cold. Not sure what to do next.
