Atf Fluid

[Alex JB]

Hi All,

I have ben reading some historic posts on the ATF thing and almost everyone seems to say use Toyota T-IV and NOTHING ELSE.

I understand this concern but I deal with oils everyday for a living and I cannot see that Mobil ATF-3309 is not suitable also.

It comes down to the lubricity properties and the viscosity index which the 3309 is designed to meet.

The only reason I drag this one up again is that I was planning on flushing this weekend and maybe changing the strainer too but when my local Toyota dealer daid it was over 50 quid plus vat for a 5 litre container of T-IV (08886-82025) I nearly choked!

I'm loving the Lexus LS ride but to flush out is gona take at lease 9 litres... if it runs into 3 of these containers... I could buy another cheap car to go to work in and leave the LS on the drive just to look good! B)

For info I have pasted some info from the Mobil site about their 3309 ATF

and here's the web site

Applications

Mobil ATF 3309 is recommended for use in transmissions made by Aisin-Warner requiring fluids approved against JWS 3309 or GM 9986195.

Mobil sounds OK but LS 400 owners here and in the USA insist on Toyota T-IV on pain of death!
