Hi ive just bought my first z 5 days now its just to much fun. its an import twin turbo just come over. I have posted the same question on the tech forum but noone is there.How do you use the auto box? I have overdrive, AT power, centre position and hold HELP!!!!!!!!I cant work it out(Jap handbook!)

Power mode will give you loads of power by shifting at really high rpm, normal mode is normal , hold mode is to make it hold the road better, by disabling 1st gear, and disabling kickdown, and using the highest gear suibtable at all times. o/d will give you a few hundred more revs, and make it go faster . Floor it and it will automatically shift into power mode disabling the aircon, giving you maximum power to the wheels, for casual overtaking of course . I think it gived you about 10 seconds of power mode.

 

HTH

Really???

 

Thats a lotta faffin around man, no wonder they blow up all the time !

The 4 speed automatic transmission is a lockup type. When in drive mode, gears change 1-2-3 then 3 lockup, giving the effect of 4 gears. When overdrive (4th) is switched in, the change goes 1-2-3-4 then 4 lockup, giving the effect of 5 forward gears. There is a communications link between the automatic transmission control computer and the engine management computer, and this amongst other things, allows the engine computer to retard ignition, thus momentarily reducing engine power, during auto gear changes. Auto gear changes therefore are very smooth.

 

 

The Japanese automatic transmission has more features than the export models. A "power", "normal" and "hold" switch is fitted to modify transmission shift points. The effect of the "power" setting is to delay upshifting, but does not alter the maximum RPM at which a change occurs. In order to change at the red line or rev limiter speed, one must operate the shifter manually. The hold setting allows 'holding' which prevents downshift into second when the shifter is set to "D", and prevents downshift into first when the shifter is in "2". Another curious feature with the Japanese version is that lock up is also available in second gear.

Andy - what do you mean when you say that the automatic gearbox is a "lockup type"?

If Andy isnt around I think I know the answer to that one. It means there is a kind of clutch that locks up the torque converter so that the drive goes engine to gears direct with no slip from the slush part (torque converter) in between. The moment you put too much power on it drops out again and re engages the torque converter.

 

not sure at very high speed tho. Saves fuel too cos no losses from the slushbox when locked up.

I thought the auto had 5 gears till someone here put me straight
