l have noticed the transmission switching to neutral (while still in D) when coming to a stop, or near stop. It doesn't always happen, but when it does there's a lurch as the transmission re-engages.
When you put your foot on the gas the RPM shoot up and then the transmission suddenly engages. It was worse when the vehicle was new, but can still happen when approaching a standstill and then trying to accelerate. l use the "grass, gravel snow" setting for city driving which seems better, probably because the launch mode is more gentle. The hill hold assist does seem to work okay though. |

Seriously? Where does it mention that in the thread - genuinely curious. I read the first post and that suggested the Hold behaviour - which is pretty overbearing. |

lf someone could supply a transmission remap to stop it from disengaging they'd make a fortune.

I have the issue on my 4 week old D350.
It hasn't been mentioned but it also happens in R as well as D. Maneuvering out of a tight space I can select R. I release the brake and the car rolls forward. I do not want to use Auto Hold DND nor should I be forced to as a work around. Any chance of rejecting the vehicle because of this? Also not happy with a noisy pano roof. |

So sorry billy2shots that you have the same issue. I honestly didn’t think to try it in reverse to see if it did the same on mine.
I rejected mine for this reason and the squealing air vents. Not fit for purpose as I bought to tow horse trailer. You need to notify the issues to the dealer as soon as. Do this in an email so you have a time stamp. Also if on PCP the finance company were great in sorting my rejection. I called them to also lodge my complaint through the finance company. The sooner you report the better. Mention rejection and things then start getting looked into! Despite 2 attempts to fix it still had the problem and I like you did not want to use Brake Hold Assist to cover up the issue. If rejecting you have to give the dealer at least 1 chance to try resolve. I have ordered my replacement as the dealer had no interest in solving with an AVC (assisted vehicle change). Just hope the new one doesn’t have the same problem! Good luck and hopefully a resolution is found. The more people report this problem then Land Rover may come up with a solution.

Just came across this thread whilst researching the issue. For what it’s worth , I have a my25 d350 . Same issue . Hesitant on take off from a standstill. Roll back when switching D to R when manoeuvring. I just swapped from a my23 d250 and this is completely different . Previous vehicle was perfect. At a standstill on hill, hill hold comes on as expected , take foot off brake switch to throttle slight roll back then after maybe .25 of second transmission engages . Only happens from a complete standstill otherwise transmission perfectly normal . Pulling out at junctions I have to try and get rolling at a crawl ahead of hitting the gas. Not great .

The hesitation becomes less with mileage. My Transit was the same, foot on the gas, nothing, nothing, BAM!! nearly gave me whiplash
It took a few thousand miles but the van eventually became much smoother. Transit Connect 1.8tdci |

Good to know . Will perservere with a few more miles . But something has definitely changed with My 25 . If I had to guess a change to the software or mapping for emission purposes ? Will follow everyone’s comments . Thanks .

I am so glad to see this thread. Will be sending it to my dealership after this. Received my D350 last year October and have the same issues. When pulling away from standstill on a slight incline the car rolls back and the reverse cameras go on. I've been to 2 dealerships and they all say it's normal. I've been driving auto cars for many years and this is the first car that does that. I still get a fright when this hapopens as it feels like I'm going to hit the car behind me. This is not normal.

Very interesting to read this as I await my MY25.5 Defender eta March. From what I can see the problem seems to be reported more on the d350 (not d250- but difficult to know significance without knowing proportion of each sold) which might align with what one poster said about higher torque of d350 and consequently different transmission programming. Anyone aware of any such problems specifically with MY25/25.5 D250?

So, noting that even with Hold enabled, it doesn't do that when you first start it up and drive off - there is a delay between selecting forward or reverse and the transmission engaging.
But, keeping my foot on the brake until it engages means there is no roll. This - in my experience - is normal behaviour for a torque converter transmission. What am I missing? |

l think people have got used to modern vehicles where they have a "hold" function so you can put the transmission in "D" and immediately take your foot off the brake pedal.
