If the engine is revving and the engine is not pulling then that means the transmission is slipping internally. In order to determine if the problem is internal or an electronic control issue you need to start first with scanning the computer system to see if there are any fault codes setting. If there are no fault code setting then the problem is internal which is most likely due to the high amount of miles you have on the transmission. If you can get the can done and post back with the results that will at least verify if in fact that is the case. Post back with the scan results and we can work from there.
