check your cable from throttlebody to transmission. kickdown cable. That cable opens certain valves at certain points of throttle position. I had to have mind adjusted - easily done with 2 people - and it shifted hard after i adjusted it.

The gov is located on the dr side of trans behind a cover that is about 3 inches wide. The cover gets popped off with a large screwdriver and governor pulls right out for inspection.
if you install apressure gage on the 11mm tap above the linkage you can instantly nail down if its a governor or throttle valve /throttle valve circuit problem.hi line pressure at o tv cable pull is due to a stuck throttle valve or tv upshift valve.
This might be a governor problem (the weights are too light), if you cannot make a WOT shift on the 1-2 shift at the desired rpm. If you are trying to shift it manually before the WOT shift point of the governer, it will not happen. Let me know?
