    Question Does D4 means overdrive?

    I have a daihatsu mira equipped with normal automatic gearbox. I want to know in which gear should i drive in city D3 or D4 and which one is more economical? A/c to wikipedia newer cars shift themselves to OD automatically, so it is the same case with my car?

    This car do not have
    one can not assume the transmission method by just seeing the gear lever...however this seems to be very similar to one of steermatic in which u can use auto and manual shifting.only difference is the usage of S mode
    when you drive at D it utilizes all the available gears and for manual you have to move the lever to S , once in S mode you just have to give it a flick forwards to shift to higher gear and pull a bit back to lower the gear

    keeping your car neutral will not help your brake perform well plus since a fellow member told k gravity acts and you are pulled downwards which i assume you understood, so my friend keeping your car at lower gears provide your car braking assistance due to engine compression...it is very similar like you drive a manual and speed up in 2nd gear you will notice that if u leave your engine at suppose 4k rpms your car will within 10 seconds be back to 2krpm or so...while if you practice same on top gear of your car your car will tend to coast more further.
    this is due to the gear ratios which get produce more torque less speed and vice versa if you shift to higher gears.since engine produces high torque when provided fuel,and the converse is also true which means it also absorbs high torque ( which u get due to rolling of your car while coming downstream ) at lower gears by converting speed into high rpms for the engine and then the engine compression plays role which i mentioned earlier.
    i hope this serves the purpose well
    so that is the reason that it is advised not to press clutch along with brake during emergency braking as pressing the clutch immed reduce the engine rpm
    correct me if I am wrong
    My dear ALLAH when I loose hope, help me to remember that Your love is greater than my disappointment and Your plans for my life are better than my Dreams.

    bingo!
    you got it absolutely right
    when u press clutch in emergency braking the brake booster casts its load on engine and engine is revving @ 500 or 800rpms so it dosent provides suffcient vacuum for hydraulic brake to work...not in most of cases but in some cars if u apply sudden brakes with clutch pressed the load on engine gets on higher side and the engine shuts down leaving HPS and hyd brakes useless and eventually you end up resulting a collision.
