Major Fluids changing questions

[quick]

Anyone who has done these fluid changes at home, is there any technicality doing them that we need to be aware of?

I know, brake and engine oil change should be nothing special.

What about the Differential which my understanding is, 3 of them (front/rear and drive dynamic, correct?) Is drive dynamic and transfer case the same thing?

How about the coolant? Just flush it?

Transmission: I am thinking of just dropping the pan and changing the filter etc? Any word of caution/wisdom here as this is the most critical fluid change?

Power steering: ?

What fluids do you all recommend for this project?

One shop I called, uses BG additive in all their fluid changes, OK?

Thanks

When you do your tranny, you will understand and thank me later...or try to do it with the little hand pump and suffer. Btw, through tranny fluid smells like car urine..get gloves, lots of em.
