PCV is simple. 5 minutes. Easier than a supercharged version, but they're both simple. You'll need a screwdriver to pop the cap, and a pair of needlenose pliers to remove the old valve. Fuel filter you need a 10mm socket and ratchet for the filter retainer, and needlenose pliers for the fuel line disconnects. They're quick-release. 15 minutes for that one. O2 sensor is a crescent wrench and 5 minutes. Easier than a spark plug. Plugs and wires are typical. Not too bad. Easier than my old 77 camaro! Transmission filter will take the longest. You need a pan gasket and filter kit. Probably 20 to 30 bucks and a couple hours. About 5 or 6 quarts of fluid when you're done.

Fuel filter should be 10 bucks, PCV should be 5, O2 part numbers and prices are listed up in Techinfo, Plugs should be AC Delco or NGK, wires go with MSD or Taylor. Trans pan seal and filter from your local auto parts store, about 30 bucks. There'* a procedure for this up in Techinfo also.

This "type" of "basic" tune up shouldn't take any longer than about 45 min! Any longer than this & you're doing something wrong! That'* with a 15 min leeway too for someone that'* never done one before too!

For the first timers, take your time gapping the plugs, and take your time with the trans filter. Getting the old bushing out can be tough. If you have two people working together on this, it IS fast. Get your helper to do the fuel filter

Man, you guys are smart. I'm afraid of taking something off and having fuel or coolant or something spilling everywere, and having to get it towed to the dealer. I'll probably have my dad help me with all of this, he has some mechanical/engine skills from working on his truck and our old tractors. Ill probably start off with the cheap stuff first, and work my way up.

should I do this before or after I put in a t-stat & tranny cooler, or does it even matter?

Consider the Tstat part of your tuneup. Cheap, too. It should be one of the first things at least. Wait on the tranny cooler til spring.
