    I'm not sure what Idle Neutral Logic should do. I never felt disconnected auxiliary clutch while D is engaged, I think that AS&G turn off engine to prevent torque converter heating. When engine is on, in D but with brake, rpm are 150-200 less than in N, of course it is because torque converter, so I think AS&G is solution for that. I like to use N, better than AS&G (battery, starter grinding, the traffic lights are here no longer than 30 sec...)

    I noticed that auxiliary gearbox change gears depends on acceleration or deceleration. Sudden start from traffic light it keeps first gear until 50 km/h and rpm over 2000, even if I after sudden start (0-35km/h) slow down acceleration (30-60) but still accelerate, rpm is still over 2000, then I release gas pedal for half second, then again continue same acceleration with same position of gas pedal and it is under 2000, driving fine. Accelerating normally it keeps rpm under 2000 and change to second gear much earlier 30-40km/h.
    Also, in traffic, I slow down behind other cars, to about 20km/h, it keeps in second gear if I accelerate normally, but it shifts down if I do it harder and feel is not good, big lag.
    When is suddenly deceleration in L, it sometimes changes 2. to 1. gear in last half meter and feel is also very bad, it does in same time changing gear, trying to synchronize rpm (belt with wheels) and unlock torque converter. Funny

    Thanks to Inuvik in other post, now driving in N is often, but only when downhill is loooong enough to keep speed over 10-15 seconds. Otherwise, in short downhills, I think that cutting fuel as Bigdezzy says sound more economic. I measure it using Torque Pro OBD2. Last week I fill up fuel twice, exactly 53 litres, exactly till cap, as i describe in other post a few days ago, and TorquePro calculate 53.32 litres of total consumption. WOW
