yea the computer is again the back pass wall of the engine bay, and im only guessing that it could be a problem... i dont have the slighest idea where the wires go, but from looking at a manual shifter in a different thred the tranny is controlled my 2 silinoids with a wire going to each, if one of those is bad or a wire is broke or grounded out it could be the problem
also your tranny might just be shot, the OD ring might be bad.
i have a hyundai that keeps blowing a fuse that controls the OD and the rear wiper, leave it to the koreans to put those 2 together, but it will work for a while then pop it could be something as simple as a fuse, diagnosis is a costly venture for a reason it sucks to do and a lot of time leads to nothing.
start small then go big, buy a chiltons manual, check EVERY fuse check ever relay (meaning take the pass kick out and swap relays in and out, it sucks you have to drive it to figure out if it works but thats life. check the relays and fuses under the hood... inspect around any and all plugs on the tranny itself look for cracks in the plastic, pulled wires (maybe one got to close to a loose exhaust).. there are a million things that the OD could fail for, if it was 2nd gear it would be easy.
good luck man, because im pretty much out of ideas - next peice of advice is call a tranny shop
