A buddy of mine has a old Desoto 4dr that's factory equiped with the 383 8bbl. Anyway he had it at the Muscle Car Shootout at BIR a few years ago. He was racing another car so he had a friends wife run it in powder puff. No one told her not to sit in the staging lanes with the motor running with the trans in Drive. It got so hot the fluid turned green. We changed fluid&filter at the track and the car made it home. It started to slip a bit later on and he rebuilt it that winter. It's the only time I ever saw Dextron turn green. Dave
