What transmission fluid do I need for C551A transmission?

[Aris the Auris]

I have a gen 2 Yaris with the C551A transmission and I need to change the fluid by I don't have a service manual or owners manual or warranty booklet. The Haynes autofix subscription says SAE 75W-90 GL-4/5. When I look up products of that description they say manual transmission fluid or brake fluid or gear oil. When I look up automatic transmission fluid I don't see 75W-90 or GL-4/5 anywhere. 

I'm at a loss and I need help. What the hell do I need to buy!?

Non of those find your oil are ever accurate for my engine oil. I know his thread is relating to transmission fluid. Are they fully reliable though?

All, bar non, recommend 5W30 which is contrary to Toyota's 0W20. Yes, 5W30 may be used as a stop gap but change to 0W20 when possible.

A Mk2 Yaris Auto is an MMT what is just an automated Manual gearbox

 

75w90 GL4 is correct, full drain and refill is 1.7L or until it overflows out the fill plug

 

Crack the fill plug loose first before the drain

Thanks Flash22, that's the oil I ended up using.

All EU spec MK2 Yaris with Manual or MMT ( Multi mode Transmission ) use API GL-4 SAE 75w.
