2nd to 1st Downshift issue
 

Does anyone experience a delay/hesitation in downshfts from 2nd to 1st.

When approaching a roundabout and not needing to come to a complete stop but at about 5-10mph, I start to go and the car does nothing but bogs and then shoots forward as it effectively downshifts. Dealer drove another one and said it is normal. Nothing like my LR4 and Jag with the same engine/transmission.

It's probably coming from the ZF transmission that LR and many other brands use. Quite a few people mentioned this 'shunt' as it downshifts to 1st on the earlier 6-speed ZF transmission. See this thread for example

Apparently having the TCM control module reset or reflashed helped some people with older software. Prob not the issue for you but you could see if they can reset it for you. A lot of people worked out how / when to ease off the brake to avoid it

My wife drove my 2018 Discovery last week for the first time and the downshifting aggravated her and she asked what is wrong with my LR as her Audi doesn't do it. I asked the SA at the dealership about it and was told the vehicle is learning my driving habits. I just have a hard time believing this since I'm moving at around 3-10 mph and the transmission can't make a gear selection until I press the accelerator pedal. I recently drove a 2017 RR for a few days and it's transmission shifted properly with no "lurch". Any thoughts on correcting this?

I have a 2018 D5 and I notice the same issue. I took it back to the dealer to have them inspect and gave a very detailed explanation of how they can replicate. It came back that they couldn't replicate it, and that everything was normal.

I notice it going over speed bumps, at stop signs, pulling out of driveways. Several times, it has cause an 'oh ****' moment where I either jamb my foot to the floor on the gas, or jamb my foot to the floor on the brake. Neither is comfortable for the passengers. I have also noticed it while driving in both D and S.

Service advisor told me that it was learning my driving habits also, and said they might try to reset it. As far as I can read on the paperwork, they didn't reset anything. Interesting piece is that my loaner during that last visit was a 2017 D5 with around 5k miles, and I could notice it doing the same thing at a very reduced level. Maybe there is something to the 'learning your driving' mantra?

X2....I have this problem on my Jeep Renegade which has the ZF transmission. I notice it more at lower speeds, driving within the city and while going over speed bumps, etc. It's annoying to say the least but I don't think it has anything to do with learning my driving style. One of the reasons I love my old Discovery is that the Rover actually reacts when it's supposed to, rather than having a delayed response.

Purple Rain... I saw your name yesterday and I've had that song going thru my head since. Funny how one little comment or word can affect someone's thought process.

go listen to the end of the song to get it out of your head. :thumbsup:

I think my Audi A7 has a ZF trans as well, and while in S it actively downshifts during deceleration keeping the engine RPM higher and very responsive. I expected the S mode on the D5 to operate with similar characteristics, but no.

:disco::disco::disco:

Do you notice any difference if you drive around in S instead of D?

Nope. I have tested that.

I've had a couple BMW's with the ZF and they performed almost intuitively. It's the way LR has it programmed to save gas. Until we get some techie types to start coding we will have to live with this.

sport mode == don't-care-about-gas-saving mode

Sport mode=does not make a difference in downshifting. I've tried every possible combination to try to get the 2-1 downshift sooner and nothing works except time. You can shift manually but that's a PIA for daily driving

At speeds higher than 10-15 mph or so, the sport mode behaves how one would expect. It holds RPMs higher when shifting, and it proactively downshifts when slowing to again keep those RPMs higher. That lower speed is where it falls on its face.

Exactly....which is where you need it most on rolling stops. The 1 to 2 second hesitation is going to get someone T-boned because there's no power pulling into traffic. Yield signs merges are especially bad.

I have had 2 very dangerous and scary situations already. I have come to expect it now, so I try not to put myself in those situations. It still does catch me, and it usually results in my foot going much further on the gas and the car lurching forward when it eventually catches up. Hopefully they realize this issue soon.

This could be a relatively easy change if it weren't for the possible fuel economy hit. Fleet mandates in the states and the vw/Audi trickery probably have engineers watching such things closely.

What's the pull away from stationary like? I haven't felt the 2 to 1 lurch in mine. But we do notice when pulling away that there can be a second or more hesitation when we put foot down before it moves. Once moving it's responsive but that initial pull away needs us to push quite far on the pedal. And if we push too hard then it tends to jump forward...
Having it looked at next week. Wondering if others have felt this in case we are told it's normal

I just got the 2018 SE and noticed this awful shift delay after a few days of driving. I wish I had caught this during the test drive as it would be a definitive showstopper for me.

Having driven plenty of cars, including LR4, this is not normal by any means. It requires conscious effort to anticipate this delay every time when accelerating from a slow speed, such as turning left yielding to traffic.

After I complained, the dealership claimed to install the updated transmission firmware, which resulted in a very small improvement. I also tried to reset the adaptive transmission learned behavior (there are procedures I found online), but I haven't noticed any improvement whatsoever.

I believe this is a bug (or a fuel-saving feature) that has to be addressed by Land Rover if enough people will complain. Hopefully nobody will be seriously hurt because of this.

When coming to a stop (or less than 5mph or so) it stays in 2nd. If you come to a complete stop and wait about 2 seconds you can feel it downshift to 1st and then taking off is fine. The problem is when you just slow to a crawl and try to accelerate (like a merge at a circle) it is in 2nd and hesitates for a good second or 2 before you start moving. No combination of settings makes it go away.

Can you post the rest procedures you did, please?

I did a lot of searching, and this procedure pops on on BMW, Range Rover, and Jaguar forums, as these cars use the same ZF transmission:

1. Turn on the ignition: push the start button (do not start the engine)
2. All the dash lights will turn on.
3. Now, press the gas pedal all the way to the floor and keep it pressed. (Ensure the kick down switch is pressed )
4. Keep the gas pedal pressed for 30 seconds. (During this procedure engine should be off, ignition still on.)
5. Release the gas pedal.
6. Start the car and drive normally.

There's some disagreement on whether to release the pedal first and then turn off the ignition, or whether to turn off the ignition first. You can experiment and report your findings. I'm not convinced it does anything, but I'm curious to hear if others will notice a change in behavior.

This is exactly what we are all talking about.

I drove the D5 in stop-and-go traffic today for nearly an hour. It is clearly an issue at 10 mph and under. Over 10 mph and the gears would stay engaged and the car responds exactly how one would expect. Right about 10 mph and under, it has a lag before it decides it is going to respond. The delay in response gives the driver the perception that the go pedal hasn't been pressed enough and then when the delay catches up the car lurches forward, depending on how hard you pressed.

To replicate:
1. Drive to a speed over 15 mph
2. Slow to under 10 mph with foot off go pedal
3. Step on go pedal again
4. ...

Thanks. I hadn't noticed it while moving - just from stationary. But my wife drives it more than me. I'll try it out
The issue at stationary is quite pronounced. Even my wife who isn't at all a car person noticed it and thinks it's terrible

It's going in next week for a couple of ****les and they are going to check this out too
