So i have an 05 Cobalt 4Dr Base. We've owned it since 2008 which at that time it had about 40K on it. We just got back from South Carolina and it now is at about 109K. It's been very good to us, Transmission shifts just fine, no slips or any issues. Manual says change at 100K if not under Heavy or Severe Conditions. My question is change the fluid and filter or do you folks recommend any other ideas. I have had horrible pasts with Transmission Flushes so i'm definitely not going that route. Im guessing from what other threads are here Normal transmission service, Fluid, Filter, Gasket and clean the magnet in the pan. Any thoughts on upgrading the magnet or is that overkill?
