If the E brake was on for a long time the shoes can stick to the drums.
You have to push the pedal hard to get the pedal to move, or the car to move?

oldkimmer has a point double check your fluid.

Did you check the fluid in park or neutral? Has to be checked in neutral. If you checked it in park it could be a couple qts. low. Is the engine revving up high before the car moves like a clutch slipping? Does it do this in reverse also?
I checked it in neutral and was full. I have s automatic transmission it goes into each gear fine. I have to rev it high in all gears for the car to move that why I was thinking maybe it could be the brakes. I really appreciate the help guys

Was the filter recently changed?

If your feeling it drop in forward and reverse solidly it does sound like a brake issue. You might try jacking it up and seeing if you can spin the wheels freely by hand. That'd tell you if a brake was hanging up

That would tell ya quick enough.
I know its been a while but still can't figure out what's going on I changed the filter filled the tranny and still not accelerating normal. I jacked up the car to check the brakes like fishy said and the front ones were good my rear tires I'm not to sure how to check those does the car have to be in neutral. On top of that I'm leaking tranny fluid from the shifter linkage on the tranny.

Is the kickdown linkage hooked up and set correctly? It will cause the exact issue you are having, if it ain't right.
Yes, put it in neutral while back tires are in the air and see if rear wheels spin freely.

Jack up the rear end and try spinning the rear wheels while in the air, you will no if something is holding them back, if it is dig into it.

No No No. Improperly adjusted throttle pressure linkage will not cause a car to not move at all. You could take it completely off and the car would still drive forward and backwards, it'd burn up the trans. with it removed or maladjusted but it'd take off.

In neutral, with the brakes off,, can you roll the car,, by pushing, in either direction.??
