Pressure control solenoid (p2714). I replaced the solenoid. Drove great for about 3 days and then went to s*** again. Seems there was an issue with the valve body that caused it to fail but I’m not sure. I started noticing delayed engagement early on and poor performance. Eventually it would take 20 seconds to achieve a speed of 45 mph lol. At the end it wouldn’t shift out of 2nd but hey, she never quit on me lol. Was getting worse on the drive from south Florida to Alaska but still made it. Got a tranny for 500 bucks out of California. 800 total shipped to Alaska. I’m not complaining and definitely beats the cost of a rebuild
