high speed power loss HELP!

I have a 5.7 88 gta. When I am driving down the freeway and stomp on the gas my engine revs up but there is no power behind it. I can still feel power but very little. But, driving at city speed I seem to have no problems. I can smoke the tires with the best of them. Any help would be much appreciated.

Re: high speed power loss HELP!

Ok...maybe I should reword my question. After another inspection I found that when I am driving down the freeway in overdrive and put it to the floor, my tranny drops 1 gear down. In drive It wont drop down any gears, it will just stay in the same gear. Is this normal(doesn't seem to be)? I have always expirenced a drop of 2 gears from overdrive in other vehicles. If this is a tranny problem can I correct it myself, with a little adjustment or will it require transmision work?
