So I ordered the thin 8 clutch, 8 steel packs from ATI for forward and direct. Got ATIs thin intermediate plate and the 5 clutch/steel pack for 2nd too. Might as well rollerize the tail shaft bushing while I am in there.
Trans worked great as is but preventing a cast iron drum from blowing through the case is a good thing. Lighter weight drums and oversized center support should not hurt anything either. Think I will run the pump as is too. It has the Trans Go spring in there and I believe I drilled a bigger hole in it too as per instructions. Clutches look really good so pressure is not a issue. I do have a new pump, they can be hard to find. 180 $ not too bad.

Still, anyone have a idea why the trans would go into neutral on the 1/2 shift ? I have had in not shift due to cable adjustment issues.
Funning thing is the tech guy at ATI had his T400 not shift on his 1/2 shift his last race and thought he rolled his sprag too. He has not had it apart yet.
