Hey guys, set to purchase an 08 black on black GS460 in mint condition with 140k, service records say it was at the dealer every 5k of its entire life for every oil change and other things. Noticed the tranny fluid wasn't on there, I'm wondering should I do a drain and fill with this mileage or leave it? I know it's supposedly "lifetime" fluid but have heard of people who never change it have issues, how are the 8 speeds holding up?

 

Also what is a good estimate on doing the spark plugs on a 460, don't think that was done and would like to get these two things done when I get the car.

 

Well do a transmission drain and fill or complete flush with new trans filter. Also spark plugs and maybe water pump. I recommend the transmission I am currently changing out solenoids and when i drop the pan and trans filter it was slug and allot of metal shavings.
