He was able to determine it was an older, non partial throttle kickdown tranny just by looking at the side of the case where the linakge bolted to?




Correct, the location of the pipe plug on the accumulator (middle hump in case on passenger side) was changed on the later case; the plug is located low near the pan rail on the early case and up near the top of the hump on the later case.

There are pics of the two configurations in my 727 photo album:

The first year for that change was '71 but not all got the change until a couple of years later. '71 was also the first year that the V8 got PTK and there were changes in the accumulator function that changed the case but the PTK function is in the valve body, not the case.
