The gearbox only drains less than half. I've not found any easy way to drain the system fully, so I just drain and refill more frequently,fingers crossed!

2.9 of 7.0 l drained.
Changing it more frequently would be my way to go too.
Are there any filters within the gearbox?

Yup, there will be a filter in the box, but, as there's no conventional sump, getting to it would be the issue

At first, thank you for the many replies!
Jonathan's explanation sounds reasonable to me as the drain is indeed at the lowest point so whatever "glunks" will end up there as well. I guess it'll be little fun adjusting for the right level when refilling .. Guess I should make an order for more ATF this evening.
Regarding the full exchange method, it's very likely not possible with the NSX (at least not the way it's done with other AT cars). They connect to the ATF pipes going from the transmission to the front cooler which contains a heat exchanger. The NSX AT does use a heat exchanger mounted to the engine and as a result the ATF is never leaving the transmission.
The only option I can think of would be to connect it to the drain and the fill-pipe (the ATL level check pipe) but unsure if that works as expected.
Hoepfully I'll find time to complete the work next week, I'll keep you updated

Maybe Kaz can give you some more insight as AT is a lot more common in Japan than anywhere else.

That would be very helpful, indeed.
In one of his blog entries (http://www.nsxcb.co.uk/entry.php?204...esh-LMA-etc-45) he reported to have drained 4 liter of ATF and another 1.1 l on top of it. As these numbers don't match with the repair manual his feedback would be highly appreciated.

Completed the work on the drive shafts today. Overall 4,5 Liter new ATF as required to bring the level between the Min and Max marks.
Shifting behaviour is still quite rough (compared to state of the art automatic transmissions). I'm wondering whether that's normal or not (no second NSX to compare, unfortunately ..
