I need a 904 trans build recipe, or a recommendation in DFW

Hello,

I've been doing some searching for the past several weeks for a shop to build my trans, but I'm not having much luck finding someone I'm confident in. It seems that nobody wants to tell me what exactly they'd do to the transmission to make it suitable for my application. I understand that shops get calls everyday with people wasting their time and milking info out of them, but I just want to know what would go in my new transmission. I don't want to spend $$$$ on what I think is a high performance transmission and wind up getting a cheap rebuild with a shift kit, and maybe some hp clutches. I've called several places in my area and they all give me the "we know what we're doing, trust us" line, but that doesn't settle well with me.



I have 2 transmissions that I can use for parts, a 1973 904 and a 1985 A999(currently in car). What I'm expecting from my new trans:

1.) Non lockup
2.) Use the low gearset and clutch pack(pretty sure it's 5 disks) from the 999, plus other parts, whatever is stronger out of the two transmissions
3.) I want it to automatically shift when left in drive at ~5250 rpm during wot.
4.) Forward pattern auto/manual valvebody with the option to be able to start in 2nd gear


Car specs(new combo):

1) 1986 RX7, approx 3000 lbs with me in it
2.) 360 Magnum, 216/224 .506/.506 114, airgap, 650 dp blowthru with a 70mm turbo, ~500 hp (want to run 7.0/11.0 index)
3.) 3.27-3.55 gears (undecided, but leaning towards 3.27)
4.) no stall converter selected yet, thinking ~3000-3200


So, what would it take to build a trans for my application, specifically? A proven recipe is more what I'm looking for. I want to do this ONCE and enjoy it for years to come. It's a SERIOUS PITA to drop my trans, and requires lifting the motor off the mounts to access the tranny bolts, and dropping the rear subframe to remove the driveshaft. It'll take the whole weekend to install just the trans so I want to get it right the first time.


Really, I just want someone who is very knowledgeable in Torquflites to build it for me, preferably in the DFW are so I can use my own cores. A warranty would be nice too if possible. Of course if that doesn't work out then I'll be stuck building it myself, so I'll need a parts list.

Thanks for taking the time......
