Jumped in the SC this morning and went to fill up when I left the gas station the trans started to slip and then wouldn't shift out of gear. Putting it in neutral and then back to overdrive puts it in the correct gear though. Trans fluid looks great. Any experts out there have any input of what might be going on in there? Just to add in it's sort of intermittent, sometimes it would shift through all gears fine but then i'd stop at a stop light and would have to put it in neutral and back to OD to get to third. Downshifting seems fine 100% of the time
