I believe the trans would have to have a low pressure vacuum in order to get most fluid out properly. and then fill until level with proper indicator mark.

 

im at 73k miles on a 07, i havent done anything differential oil change or sparks plugs. my brakes looks kind of dirty but i been wanting to do maintaince on it too. i feel like my transmission is slipping..

they also said 90-100k miles for differential for gs's, if i remember same goes with spark plugs?

 

Yes, this is standard for the Canadian service schedule. Why it's different compared to the US one that doesn't have any replacement schedule at all is a total mystery as much of the climate is the same throughout the northern half of the US.

I think Toyota charged me all of 60 odd dollars to drain and fill. I'm sure it was cheap partially because when you drain it only a small amount actually gets put back in.

I did mine early and will continue to do it every couple of years because it's cheap and certainly can't hurt.

 

i have 95K miles on the 06 and took it to toyota and they said you can't change the fluid, need to call sewell and see what they say
