Ok, so there is a front differential, rear differential and a transfer case. Correct? Just wanted to be 100% sure. When you are saying front transfer case but on the rear (that sorta throws people off.....maybe LOL). Meaning I would need 6 washers TOTAL (front differential drain, front differential fill, rear differential drain, rear differential fill, transfer case drain, transfer case fill).There IS a front differential; it's in the transmission. There is a front transfer case, on the rear of the transmission. Change all of the lubes all at once. The ATF is type FZ and not easy to find. Check Amazon.
I plan to just bring it to the shops to do it. If I want them to do ATF I would need to order the Mazda ATF FZ. The differential I may just use whatever they have in stock. Drain and refill ATF only drains that much. You probably need to do it twice and I am not sure if they do any measurement for you or end up over filling or under filling.
Brake fluids at 32k........is that early or can wait a bit?
