There are way to many positive threads about this transmission so i'll add one:
My transmission completely went at 50,000 miles (while i still owed 10,000 on the car). But the guy at the tranny shop says that either it was an old transmission that was swapped in, guy before rolled back the clock or he did a 12 minute brake torque letting the tranny shift back and forth between 1st and second. The new tranny and torque convertor are great though, feel extremely strong, I definately think the tranny could hold up with some added boost.
