Th400 diagnosis
well my car was running about 1/2 second slower and i narrowed it down to the transmission. Forward clutch pack looked like new. direct clutch showed hot spots on the plates and dark burnt rings on the clutches, intermediate was burnt up pretty good with alot of hot spots. Everything else in the tranny checked out ok.(air check) I run a full manual valve body.(cheetah) This is after about 2-3 years of abuse, what could cause the slipping? would it be ok to just install new clutches and steels?
