So is changing the gearbox oil what is referred to as "Drain the reducer" in the Peugeot iOn servicing book? If so, this should be done every 5 years/62.500 miles.

And I've just had a look underneath the iOn. Is this the gearbox drain and fill plugs?

Valvoline maxlife ATF,

Is an ATF the right thing to use in what is essentially a single speed manual transmission and differential ?

The properties of a typical ATF - which is designed to work with wet friction clutches, a torque converter, and act as a high pressure hydraulic fluid for a valve control block are not even remotely similar to the properties of a typical 75w-90 manual gearbox oil, which is much, much thicker, primarily due to there being no pumped oil flow in most manual gearboxes. (So the oil has to be sticky enough to cling to the gears)

Not saying you're wrong, but I find it an odd choice if they did use a standard, thin ATF fluid in this application...

75W-90 Hypoid Gear Oil is usually only called for in differentials which have hypoid gears, where the teeth 'wipe' across each other which cause a shearing action of the oil. Modern manual transmissions don't call for it's use anymore

Guess what Dodge called for as lubricant in a 5 speed manual transmission in a one ton diesel dually truck? Yup - ATF. Like you, we thought many other lubricants would be better for that application, so we used 10W-30 motor oil in ours with success

See https://youtu.be/NW6liZWTBgo
Oil for the gearbox is ATF SP III, such as TRIPLE QX ATF Plus Transmission Fluid

I just recently changed it on both of our cars. Could not tell a difference in drive-ability or sound. Interesting that the Ion, etc., is calling for a much different frequency for changing it than here in the US with the NA iMiev?

I was able to get the Mitsu brand oil from White Bear Mitsubishi online parts store (on amazon) for $12.88 per quart with free shipping :)
