Clemson - are you saying this is different from my 1981? I thought they were all the same. If they changed and made it backwards in 1984, that is news to me. I have a 1981 300SD and mine functions the way I described it; the upshift is designed to happen with no vac and it bleeds off immediately when you go WOT. I cannot fathom why they would have reversed the operation.

Can anyone confirm? Kerry - are you out there; do you know?

Thx.
