Hey guys I'm new here. Got a 2000 model magna. 3.5 Litre V6, automatic. Stock as a rock. All it has is lowered suspension all round. Just wondering if anyone can help figure out an issue with my car. It drives fine most days until I get above 80km/h or onto the freeway then the gearbox seems so jump a few rpm before it changes gear. Seems like its slipping kinda badly. I've heard stories about a gearbox computer being the problem. Could this be the case?
