I am going to change all the fluids in my '99 Dodge Ram 5.9 QC 4x4. Engine, Trans, Transfer case, both diffs. Should i change the coolant??? My question was about changing the transmission fluid, i am changing all the fluids because i just bought it a few weeks ago (don't know when they were last changed), do i have to adjust the bands??? Should i bring it to a mechanic to do the transmission? Also, do i have to change the fluids in both diffs or do you not have to change them??? Oh ya, the truck has 76,000 miles on it.

Thanks

 

Bands may or may not need adjusted. You may want to have the dealer do that. Change both diffs your self and do not forget the posi additive if you need it. When changing radiator fluid cut the juice with distilled water (do not use tap water!!). You may as well check the front brake pads and check/change the spark plugs. I had to change my plugs at 70K.
