Got tips? - Yeah, clear your schedule for a while....lol , buy a new low/reverse servo, selective thrust washer kit, new bands (intermediate & low/reverse) get a master rebuild kit with new clutches and steels, a tub of vasoline, plenty of mineral spirits, and a B&M shift improver kit.
Pay close attention to the details, and +1 on the bad shoe production video, its a must have. Like mentioned before, Ken does an excellent job demonstrating overhauling the C4.
Oh yeah, and if your #3 thrust washer (may be called fwd clutch to hub assy) is bad, good luck..... It's obsolete for the early C4's.... Your best bet is to find a good used one.
Another good source for parts is bulkpart.com
What if I found a guy that whill rebuild it for $400 including a raybestos full rebuild kit...and reuse my almost new B&M shift kit thats in....$425 if he puts in a new one. This price is of course me pulling it and installing it. 1 month warranty.
Good idea? Im not afraid of getting my hands dirty...obviously i own a mustang lol but this seems alittle more intricate...
I'm getting ready to do the same thing and already purchased Ken's C4 overhaul video set , Sonnax billet C-ratio servo and cover kit, TransGo 47-2 shift/reprogramming kit, a master rebuild kit w/Kevlar forward band and a free tub of Dr Tranny's green assembly goo compliments of the seller of the rebuild and shift kits. It does seem pretty intimidating if you haven't done something like this before but it is not rocket science either. You will read all over the VMF alone about all the folks that have rebuilt their trans themselves. As long as you have the proper tools, direction/instruction and quality parts you can save yourself a few hundred bucks that can be put towards other cool things for your Mustang. I'm also pulling the 289 and replacing the heads. intake mani, carb, cam, oil pump and a few other small items. The bottom end is still pulling good compression so leaving alone for now but may change my mind once I have the engine out and if in the budget. My point being it can all be done as DIY projects, just dig in man, best of luck!

Right in the middle of my C4 rebuild right now. The trans ran great when I parked the car years ago, but even then it blew a lot of fluid. Bought Ken's Badshoe Productions video and highly recommend it. So far during my rebuild, I have found a damaged pump gear and a servo housing with galling. My clearance in the forward clutch is too great so I am getting some thicker plates. I spend $200 on a total rebuild kit from Makco. I got all new gaskets, clutches, clutch plates, rings, all bushings, that weird spring in the forward clutch, thrust bearings with selectives, modulator, and sprag kit. I had to buy about $75 worth of tools off eBay, a better set of snap ring pliers, and another $50 for solvents, trans oil for assembly but not to fill on completion, and brake cleaner. I haven't replaced the torque converter yet but will do so with a stock unit for probably $80.
I am rebuilding it the way a service probably would not. I would guess that some of the back yard deals don't include difficult to access parts like the o-rings in the bottom of the clutches and certainly no bushings. That was my experience after tearing into this thing and recalling that I had it resealed about 20 years ago. It is not all that difficult particularly when I have the laptop on my toolbox with Ken's dvds plugged in coaching me through the maze. I encourage anyone to rebuild there transmission based on my present experience.
I am not finished, so I reserve the right to deny all encouragement in a couple of weeks.
