Doesn’t seem too bad if you can shift down with the gear selector. Sounds like a problem with your vacuum modulator. Have you had the vacuums’ pressure checked? Also what happens when you floor the pedal driving up hill or on a flat road?

Not sure what you mean when you say it feels old, but yes go get the vacuum line's pressure checked and see if that's the problem.

If its going "chug chug" off the line and there is no real power the cylinders aren’t firing efficiently, that could be due too a large number of things, however if it's been looked after it may only need a tune-up, replace the spark plugs and the fuel and air filters to start with. Was the car "old" before you had the transmission problems, or did they happen at the same time?
