What exactly does the A/T button Power or hold do on the Auto, I can't tell any difference when using it. Thanks

A search may bring up a better explanation but I'll give my understanding of it...

 

"HOLD" disengages kickdown and cuts the power to the rear wheels.......from what I can make out its used when its raining, snowy/icy roads, you get the pic, when its slippery conditions.

 

"POWER" will hold out the revs more and for longer before it changes up a gear.

The Japanese automatic transmission has many 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 that 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 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.

 

Can't remember where I nicked this ...

Thanks, thats what my own views where similar to. I was starting to wonder though as mine is a Jap Z32 and the button didn't seem to change the rev patterns in POWER mode as it will red line if allowed to but more so in kick down. Not sure what you mean by "lock up is also available in second gear"

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 automatic transmission fitted to the turbo model is stronger than the one installed in the non turbo. Although the gear ratios are almost identical, there are many minor differences between the two transmissions.

Thanks for that.

Also when hold is selected you pullaway in 2nd gear.
