Visitor, 2001 Mitsubishi Diamante, 69,300 mi
Trasmission stopped working in all gears while travelling at 40 mph. Engine ran, but each gear felt like I was in neutral. Problem was a spring which cracked and set off a chain of events which killed the pump and other key components. Mechanic said the disc type spring was of inferior quality. Tranny had to be completely rebuilt including replacement of upgraded spring.
