Sumbish, I've started it 3 times with links and keep losing my post about the time I get about done. So fugg that. Here is a quick list.
Banner Kit (Does not include Steels, Usually only steels that need replaced is in the 3-4 clutch pack, and when you buy the Alto Commerical Pack, or Z pack, it comes with steels for this pack, so reuse all the other good steels, but save your money, cuz the steels you'll need are in the aftermarket packs)
Commercial Alto 3-4 Pack (Some will use Zpak instead)
Beast Sunshell
Corvette 1-2 Servo
29 Element Sprag
Complete Bushing Kit (Usually less than $20, so just do it. By the time you buy common bushings by singals, may as well just buy complete kit and you have all the bushings)
2-4 Band
Shift Kit (Usually TransGO Jr or any other kit that will include the .500 Boost Valve. Cheaper to buy the kit that corrects several problems, rather than the .500 Boost Valve as a single item)
New Pump Vanes (And a new rotor too if its a 7 or 13 vane rotor. 10 is best for all applications. 7 is not enough, 13 is to many and puts to much pressure on the rotor, and also makes the rotor thinner with 3 more vanes. Common to see a 13 vane rotor broke or severly worn)
Sonnax 3-4 Release Springs (I'm now convinced this should be done)
Then of course check the valve bores looking for half moons with a flash light. Sometimes you might have 2-3 valves that need attention. In that case, rather than handle all 3 valves, its cheaper to by a recon valve body. I don't have all the tools to this anyway, so many times I do end up buying a recon valve body. Unlike most trans shops, they don't even check the valves for wear. They disassemble, clean and reassemble. Then you wonder why you're getting 1870 codes etc, or crossover pressure bleed etc. For anyone at home attempting to buildyour own, I'd just suck it up and buy the recon valve body. When you do, many corrections and updates are usually fixed if you get it from a reputable place.
I think I got it all. Not sure Pops. I may have forgotten some things. And this is just for a basic OEM build. Nothing Hipo at all, or I'd add other things like sleeving the input drum, and if real Hipp, hardened input shafts at least and possibly hardened output shaft.
