I am going to be doing a complete fluid change on my 01. I am looking for a recommendations on what fluid you guys are running or what works best in these 24 valves. I will be doing coolant, engine oil, atf fluid, and rear diff. Should I run any additives? Manual says to run something in the rear diff. Truck has a little over 80,000 miles on it and is an auto trans. It is a tow rig 75% of the time but not a daily driver. Looking for good quality stuff that is affordable and readily available. Is there anything else I need to do while I am doing all this??

Well finally got the oil and diff fluid changed today. I used valvoline premium blue 15-40 and valvoline 74-140 synthetic gear oil. Oil wasn't bad but diff seemed pretty nasty. Just got my parts for the tranny. Was planning on adjusting bands but have read not to unless you are having problems. Pretty sure what the answer is going to be but..... adjust bands or.not???

Always adjust bands, i dont understand why they say not too

I say anytime you drop the transmission pan you should always adjust the bands and inspect the condition of them as well. Foolish not to adjustment them while the pan is down.

That was my thinking. I plan on doing the adjustment. Just have to remember in/lb not ft/lb

I thought I saw a write up on here somewhere about adusting the bands but couldn't find anything. I have found several other websites with info. Anybody have a link?

You could download a service manual and get the procedure on how to do it.
