The 999 seems to have all the goodies from what I’ve read like wider bands more clutches better planetaries .What 904 should I look for as far as yearsA different transmission. If you don't want lock up, don't even bother with that 1988 unit. I've said this many times and 360duster knows - trying to make a 1978-up lock-up unit into a non lockup trans. is really difficult if not impossible because of the intricacies of particular parts involved and actual availability of said parts.
Unless you are over 600 hp (which I doubt with a 318 but hey, what do I know) or if the truck is real heavy, any garden-variety 904 variant should be fine as long as you build it with good parts. There are thin clutch/steel sets that you can get for more holding power. Billet spring pack and servos, 4.2 lever, good bands and struts, good valve body, done. Either A&A or Cope Racing should carry all this stuff.
I run a 84 Diplomat lockup tranny with a Turbo Action 10" converter. Converter has no clutch. Made a brass plug to block converter circuit in the valve body and installed a TF2 shift kit. Trans has low gear set and 5 clutch up front, works great with my 400hp +-50 sbm.

Why not run lockup? Lack of converter options?

Is Paul Forte from Turbo Action for Contacting ?I built my car as a street/strip and did not want a locking converter. I drive 50 miles to the track, run the crap out of the car, and return home. The turbo Action 10" S800 is a tight performance converter. You can get it with 26 spline count to fit a lockup input shaft. Call and talk with Paul Forte. Any good converter can set you up.
