How many automatic transmissions built in the 50s have not been rebuilt? I
would guess none. The data plate on my m211 transmission stated it was
rebuilt in 1968. I replaced it in 1999. I have talked to most of the owners
of it after it left the military. Everyone says it had never been rebuilt
till I replaced it after it lost low range. My Chevrolet blazer was made it
85. it has been rebuilt once. My wife's Chevrolet S-10 is a 86 and it has
been rebuilt twice.
