i have had the same 727 in my duster since 1994.i hear all the stories on both trans issues.i listened to a local trans guy whos car had a superstock record for a couple of months 426 maxwege auto car.
i played by his rules on the burn out and no dryhops. two seasons ago i got to see a car blow up the front drum. i had him put in a billet front.
it never broke. i get it blessed every couple of seasons.
the 727s are strong and if you do not brake the sprag in the water box they last.
