New here from WNY-rolling the dice here!

Hi, I have recently purchased a 2005 SR5 with the 4.0L V6 with 200k and will be changing all the fluids in it since the only fluid changed regularly has been the motor oil.It runs and drives great.My question at this point is: would I be causing a problem by changing the fluids in the transmission,transfer case and both differentials?I want to do these services before I do a complete check over.This is a great forum and I have tried to read as much as possible before posting this question.Sorry about going over the 5 line limit rule,tried to be brief as possible...:fishing:

I don't think that would be a bad thing. For the diff's it's just drain and fill. Shouldn't hurt at all. For the tranny I would drop pan and refill or find a shop with a t-stat machine that puts new fluid in as old fluid comes out.
