I'm at borcherding in mason ohio talking to my buddy Johnny. He says what is common is that a solenoid could be hanging up. He recommended the same as you guys to drop the pan change the filter refill, and cut apart the old filter to make sure there isn't any clutch material in the filter. Then go from there. $800+ for a solenoid switch if that's what it is. But he might do some side work for me. I'm really debating that shift kit if its worth it. The reviews on it are great.
