The transmission used to work just fine, now it will only go into reverse or 1st. I had an issue with a busted transmission modulator valve where it was busted and letting tranny fluid pull back into the intake. This would cause a huge smoke cloud. I replaced the modulator and hooked the vacuum line back up. No more smoke but the transmission will not shift out of first gear. Am I missing something? All lines are hooked up as they were before the problem but not sure what could be the issue. Thanks

it's an old hydramatic, trans. , is the filter clean? level is correct? a dip stick , hot, running engine, in park.? DO not overfill it or it foams up and wrecks the box.
step 1, is pump pressure. (at test ports)
stall test: 1st gear. fail? (rpm, check, stalling the TC)
the governor has screens that can clogged.
TV cable set right not rusted and stuck fully retracted (would delay shifts not kill them)
there are other failures, all deep inside the box. servos and clutch packs.
