Make sure you have a good vacuum signal to the vacuum modulator. If vacuum feed is OK consider replacing the modulator before condemning the trans.

1. What Tom said... My 65 which sat for over 20 years, had basically the same issue. After the folks here helped me out with suggestions, I first replaced the modulator. Still the same issue. Next was the vac. hose. Found it to be completely clogged. Replaced it, and she shifts so Purdy.....

Dittos to above , plus, keep checking fluid level; even after only a short drive down the street.  

If the torque converter was empty and the trans was completely drained….it's gonna take

a bit of circulation to get enough ATF to the converter, pump, valve body etc.

 

I had the same thing happen to my freshly built T400.  I freaked, since it wouldn't shift

after a brief drive down the street.  Ended up I was just low on fluid; even when the initial stick

reading showed full.  Drove it a block or two…. needed another qt. …. etc. till she shifted just fine!
