Here’s the results of my friends FRESH 727 in his small block Indy headed street strip transmissions after a few street trips doing a few things a car that runs 10.30’s shouldn’t do. My son pulled the transmission for him and another friend and I tore it apart yesterday afternoon. Metal from the drum contaminated all the clutches so it need s new drum, band, and clutches. This is the lip that holds the spring retainer.
