W92ls400

Hello, guy..I just got the 92 ls400..it got power steering (slow) leak..I looked on the manual..it said use the transmission fluid Dexron II for it...but auto supply shop recommand the Dexron III (dexron II no longer product). can I use this for it? it's kinda red color fluid..but my old power steering fluid is light brown (like engine oil fluid). can I mix them together? or do I have to do a full power steering flush? if so, is there a guide for power steering flush/drain? thanks

Ok...after reading thru most threads from "power steering" search..so I can use the Dexron III for my power steering..but cann't seem to find the answer for: can I mix the old power steering fluid (golden color) with the new Dexron III (red color)? or have to do the full flush? can this be DIY job or only shop can do? thanks
