I'm guessing being able to cut a 1.54 off the foot brake and running that same kind of spool up (125 shot) on the street is what caused this:
overdrive gear? (I don't know squat about automatic transmissions)
The little nub that is sticking out is from a shaft behind that gear, is that the output shaft? here are more picts:
The only other thing that concerned me is that this thing seems like its a little burnt or has wear on the back of it:
And the teeth on this seemed kind of worn but I dunno if that is normal:
Can I just replace the broken parts and go or is there a high probability of other broken stuff in this thing? I have my original BRF core in my shed and was considering taking some of the hard parts and putting it in this transmission. I just want to get it up and running while I gather the parts to put in a 400.
As a side note, that shaft that broke is TINY. I can't believe that is what is transmitting the power to the rear wheels. It's only about 7/8ths in diameter and hollow.
What kind of 400 would I need to stand up to the abuse I'm dishing out? I've been told that even a relatively stock 400 is pretty tough to kill. The car ran a 1.54 7.0@95 11.2@118 on the only quarter mile run I had a chance to do. That was with something like 55% torque converter slippage. I crossed the line at around 5100 in overdrive.

No wonder it broke!! Read the full throttle blasts in overdrive thread. You should be racing in d not od You can get a 200 that will handle your power and retain the drivability of having 4 gears instead of putting a 400 in..You just cant abuse the tranny..Im no tranny guru but you cant just replace what broke either cause trannys are precision instruments if all that craked and broke theres gotta be metal elsewhere in the tranny converter and cooler Imo...HTH
I don't know what kind of rpm the engine would have been turning.
