The front seal on my 1984 GMC's TH700R4 finally failed completely while cruising on the freeway. What a mess-the enormous clouds of smoke from the boiling tranny fluid alerted me to this terrible snafu. The real surprise was the repair bill- $3000 to remove/install a GM tranny (3 year warranty)
. Does this sound reasonable?
