    It does shift down better in Sport but that tee intersection example is the classic situation that it struggles with. For this situation I find that paddle shifting to the best gear early works quite well or I just take it easy and don't get too excited.

    Do you use the paddles at all????
    If not give them a go.1 touch on the - will give you the ground speed matched downchange you are chasing.Do nothing else and it will revert to D after a short time.Extra - will give you more but will remain in command shift,hold the + to return to D.
    Will make sense when you play

    I know how to use paddle shifts but I don't. Given I bought an auto I thought I'd leave it in auto thanks

This is up hill and then turning up hill. Frequently the car has almost died for a couple of seconds when I have turned into the intersection. I have mentioned it a number of times to the dealer but am told it is the turbo spooling up and hence a lack of power. Not happy about it but as with the roundabout adjust my driving style and simply don't pull into the intersection if a car is coming within 5 kms.

    I was under the impression that the reason there's two turbo's to start with, was to deal with turbo lag and "keep it in the zone" so to speak.
    I had an incident today where everyone came to a screeching halt in front of me, so when I'd almost stopped, I checked the lane beside me, and scooted out,,,, not . The car virtually stopped and propped before it decided to get going,,, but wow, when it did it did then move,,,

    The transmission tries its best to be in the most appropriate gear but sometimes it just doesn't have time to change back to the right gear for your input. Other times, it's a gear behind as it's expecting a sedate driver who's happy to take off one gear higher and gently cruise off, using the torque, rather than warp factor 9. At the end of the day, it's programmed for a gentler driver, not Robbo driving his R8 wanting to do skiddies at every intersection Gearbox Behaviour

    My last loaner was a SE 3.0 with less than 1500ks on the clock,one of the demos.
    When I got in it was like a rocketship,obviously as a demo it got punished a bit.
    At the end of the day when I handed it back it drove just like mine.I told the service man(it was his drive) I retrained it and he should stop thrashing it.He laughed,told me you cant tell how a loaner is treated as soon as you get in after it comes back.
    I don't thrash other peoples gear,treat it how I treat my own.I was impressed with the difference between SD and TD,out of warranty I would upgrade

    I find I can limit the "lag" by light use of the accelerator when starting from a standstill. With light use of the pedal the engine uses its torque to get going in the gear it wants. If a heavy right foot is used, then the computer thinks "oh the driver wants to go faster than I thought, so I had better down change", so you get the hesitation as it changes down, then the zoom.....

    After a TD5 D2 and a TD5 Deefer(both manual)I would never use the word lag to describe the D4 performance.If you want economy drive like an olde fart like I do,if you want go go,use sport and command shift.
    Last year I had Tailslide Ron as a passenger,I was towing my HEAVY(2T) camper trailer,we got stuck behind a Hilux and camper trailer on a long hill.Was in sport,nailed it and away we went to get around the obstacle.Impressed Ron somewhat,he said his D2 V8 wouldn't have accelerated like that without the camper trailer
