Interesting, just rang my local Toyota dealer at Tamworth, they said they need a part number, not just the name. So rang local Lexus dealer at Birmingham, they said I need Toyota ATF WS, which is different to what I was told. Also they recon the total capacity is only 3.6 litre. Still waiting for my manual in the post, I suppose they are the experts, has anyone else heard of type WS? Good news is only £15 a Litre.
