904 Clutchflite

Sure, you are going to have failures if you push the components past their limits, but at the same time we can't just start worrying that the trans is going to fail as soon as a clutch is mounted to it either. I totally expect problems if I push the trans hard enough or don't have the valve body set up right. Some of the shift shock loading can be absorbed within the application of the clutch packs and application of the bands.
Remember, the 727's got a bad rep in street cars because most guy's were using transmissions set up for all out racing.
I'm doing a 727 for a guy at the moment because he's does not like the harsh shifts the manual valve body gives him and want's a softer shift.
