check the tranny fluid if its brown then the tranny is bad. if you have arcing wires then that is your problem fix them then see if it is still doing it.

Re: car acts wierd on higway.."tranny or miss related???"
You should feel it lock up like a 5th shift. You can tell if it is locked up when you give the car a little gas when cruising and the rpm's don't change. When the gas is depressed further, it will unlock. Even further will result in a downshift obviously. You could have a "loose" converter that isn't locking up causing the symptoms you describe. Is your TVI cable adjusted properly? Just throwing out some possibilities for you.

Does it shift to 4th? Have you tryed a dead stop then WOT through all the gears? does it still do it? does your car ever reach those RPM's in the first two gears or do you drive it in way that it shifts before it gets that high? I wonder if your just not gettin enough fuel at that RPM maybe fuel filter... cheap and easy fix. But also the arcing does need to be fixed before you assume it's something else...
