Hi guys, I was shown this way by the kind people at Ford Muscle. I need your advice ! Sorry for the long post...
'64 Ford Falcon
3.8 Rear Gears
347CI SBF around 420HP
AOD from '86 Mercury Cougar
2" O/D Band & Mech Diode
A+ O/D Servo
Sonnax Boost Valve
New Stamped Steel Direct Drum
Alto Direct Clutch Power Pack
Heavy Duty Input Shaft
OEM Quality Overhaul Kit
(5 Forward, 4 Rev, 3 Int)
Baumann Recal Shift Kit
(all medium settings used)
All parts supplied by Baumann Eng.
Also all new bushes and torringtons
Edge Converter 3000 stall
Mercon V fluid
TV pressure set 5 psi at idle.
On test drive, 1st and 2nd gear seem fine. Third would only drop in once trans had warmed up and engine revved to around 5K. Overdrive intermittent and only when cruising at around 80mph. On coasting to a stand still, the trans struggles to downshift, trying to stall. After around 5 miles noticed a whine (like a supercharger!) that steadily increased in volume. Dropped the pan and found a couple of flakes of metal, so pulled the trans again and stripped down. Found that there was some scoring on the side of the pump gears and housing. The direct clutch was completely toasted, blackened frictions, overheated and warped steels. The forward clutch too shows signs of overheating. The new frictions are heavily worn and the steels dis-colored, not as bad as the direct clutch. Also, one of the bushes in the reverse shell had welded itself to the forward sun gear. This appears to be where the metal debris came from. The other bush is in as new condition !
So the question is, what went wrong? How are these failures related and what do I need to check for ?

Check that the pressure regulator valve is freed up and boost valve is assembled in the pressure valve properly. This could cut off lube flow.
Also, once back in the car, test the cooling system to see it is flowing well.
It sounds like a serious lack of lubrication, since you messed up the front portion of the trans, I would check the front lube system with the converter/cooler.
The rear is lubed by line pressure
As for the Direct clutch, check the seals and seal rings, and output shaft tube...air test is your friend.
Lastly, you DID have the TV cable hooked up and it functioned with the throttle?
