have someone rev the engine and see if a healthy blast of exhaust comes out the tailpipe your catalytic may be clogged
Does the engine rev faster when you try to exceed 35? Or does it seem to stay the same. Have you tried the other gears? Beatupchevy has a good idea, catalytic, but you will get many good ideas....need more details for a more specific answer.
It will Drive just fine but when u gave it gas it will only go to 35mp that's it

I had a few older cars that when you hit the gas nothing happens yet in neutral or park you can rev the engine , never figured them out , bad gas ? vacuum lines ? just don't know
