sorry that didn't work for ya, i'm really out of ideas then. Hopefully someone else will chime in here shortly. I know there are a couple of vacuum related sensors/switches that have a major impact on how the tranny shifts, maybe one of those is clogged or leaking. is your vacuum system in good opperation?
