    99.99% of the time the car is either in D or in P

    Trouble reversing? (Joking) I must confess to giving S a lash every now and then.

    I think the car spends less than 0.01% of its time reversing :p

    Slightly off topic, but whats the correct parking procedure for an auto?

    Would it be put in P, keep footbrake applied, apply E-brake, release footbrake (minimising the "bounce")

    Or put it in P, release the footbrake, then apply the E-brake?

    I put on the handbrake,put it in P then release the footbrake. I hate it lying on the parking pawl in the box:mad:

    Always leave mine in drive. Makes a big difference getting away from the lights to, often a good 20-30 metres down the road before the car behind has even started moving.
    The reason for that is that most drivers here go elsewhere in their minds when at traffic lights not because they are driving manuals.

    Stick it in P and walk away, unless on a hill where I turn the wheel so the car will roll towards the kerb and apply the parking brake.

    When I'm in an auto it's left in D and I use the handbrake at traffic lights. I'll only put it in P when I know I'll be stopped for more than 2-3 minutes. And brake, handbrake, then P when parking.

    That's with a Borg-Warner 35 transmission which has 3 'D' positions in my one (Daimler V8). D1 uses all 3 gears, D2 uses the top 2 for 'economy', and L locks in gear if you want to make some noise, or will kick down depending on speed.

    I had a 7 speed DSG passat from work for a while last year, the autohold is very handy at lights alright and DSG is very smooth.

    The below is a general 'signature' and not part of any post:

    FYI, if you move to a 'smart' meter electricity plan, you CAN'T move back to a non-smart plan.

    You don't have to take a 'smart' meter if you don't want one, opt-out is available.

    Buy drinks in 3L or bigger plastic bottles or glass bottles or cartons to avoid the DRS fee.

    Have an automatic at the moment and if I foresee that I'm going to be stationary for more than 5 secs I pop it into "N". Also recommended by the manual. My parking procedure is, foot on brake, into "n", Jack the handbrake and let it settle and then into "P". I'm on hilly terrain usually.

    put it in P and apply the handbrake first, the mechanism that puts it in "park" and locks the driveshaft is very expensive to repair , make its life as easy as possible.

    I always just just put my foot on the brake. I didn't get an auto to be pissing about with the gear stick at lights

    When you're actually parking you should make sure the car's actually securely stopped before putting it into park by fully applying the foot brake.

    *NEVER* use the Parking Prawl (P) setting to stop the car! Even from a very slight roll. It literally puts a pin into the output shaft of the transmission on most automatics.

    Usually it's protected by software or by hardware interlocks that prevent it from engaging if the shaft is still rotating, but it's possible to engage it sometimes.

    That's why I wouldn't really recommend putting an automatic into park regularly. It's not meant to be used that way as part of normal driving and is only intended to be applied when the car's stopped completely for a long time. You risk accidentally putting huge pressure on the parking prawl accidentally and causing a major repair job to be required. They can sheer / crack under pressure.

    Also *NEVER* park using only the Parking Prawl setting. It's intended to lock the transmission, not hold the car.

    Pawl, it's called a pawl. Spare us the lecture we're all big boys and girls here and know how an auto box works.

    I drive an older 2L auto and usually flip to N when stopped for more than 30secs or so. The aircon is always on in the car due to heat and/or humidity and when the compressor kicks in the engine turns over at about 12/1300 RPM when in N, in D the engine is under strain and drops 200 or 300 RPM, this has to be putting strain on something and also somewhere is dissipating a lot of energy, most likely as heat.

    i have 5 autos and never go into neutral. If you shift to park and someone rear ends you then it will ruin the box.

    In my old 6speed dsg Gti there was a noticeable load on the gearbox when in D at the lights, once it was popped into N it dropped back 100 revs or so which was a noticeable difference. Whereas with my mk 7 GTI with the newer DSG box(dry clutch I believe) flicking between D and N doesn't seem to make a difference to the revs so feels less 'uncomfortable' on the car so I leave it in D

    So I think the question is too general to give one single answer, depends on the gearbox
