I've got a 727 trans but not sure what year it is. Here's some numbers, PK4028412 5512 5082, any ideas?

PK4028412 I think came on the 1976-1977 400 CI Low Performance engine.

Can't confirm the year (last night in Kentucky), but at least it doesn't have a lock up torque converter. The early years of lock ups were not very good longevity wise. For a mild street build with better clutches, steels and a shift kit, it'll get the job done!
