I was also told to check the vacuum hose, but for that tranny, its not showing anything about a vacuum modulator in the repair book

No modulator valve on that one.
Is engine running good and fluid level good engine running hot?
Is the TV cable from Throttle body linkage to transmission hooked up and working and adjusted good?
Does it have a good double tension on it?
If all of that is good pull governor and check plastic gear on in and inside valve for being free movement.
Post back what you find there.
