As above are there any differences between :confused:between UK and Jap Z32 TT auto gearboxes?

I don't think the UK auto box has power and hold modes.

uk version has an oil cooler

Autoboxes are interchangeable. The UK boxes had an oil cooler hooked up as standard (JDM's were cooled through the radiator end tanks). The "power/hold" button in JDM cars is linked to the Autobox ECU, not the autobox itself. Therefore you can use a UK box in a JDM car and vice versa.

PS - regardless of what car the box comes out of it is ALWAYS a good idea to add an aftermarket autobox oil cooler.

Dan, What do the power and hold modes actually do? I've got an owners manual for the UK and Australian Z's and it doesn't mention them.

I'd like to known about the power & hold modes too!!

i have fitted a jap box to my UK car, no probs!!

In relation to the Hold/Power button in JDM cars:

 

Hold: starts in 2nd gear, shifts up early and kickdown delayed. This is primarily for fuel/emission reduction purposes or when driving in slippery conditions.

 

Power: for more "spirited" driving, shifts higher in the rpm range, kickdown more aggressive.

 

Leaving the button in the middle is a happy compromise between the two shift profiles and suitable to most every day driving conditions.

 

Disclaimer: the Hold position will not aid you when driving in extremely slippery conditions. It is not linked to the ABS or traction control system (which the 300 doesn't have unless an aftermarket RaceLogic system was fitted). It is primarily useful when driving off and minimising wheelspin.

Can the Hold/Power setup be retrofitted to UK cars?

can't see why not? Just need the ECU and wiring with a button?

I have a JDM box on my uk, with no problems; however I had an additional cooler added, and my rad one bypassed, funny enough I have noticed a drop in running tempretures since then!

That'll be correct as the gearbox oil is cooled in the end tanks of the main radiator. That will have a heating effect on the coolant and so if you add an additional A/T cooler the main rad temperature will drop. This also means that your gearbox oil is running cooler and therefore less prone to degredation and burning.

cheers for the info Dan :bow:
