I have an 05 3/4 ton 4wd with 135K miles. Recently it shifted really hard while pulling a trailer with a mower on it about 10 miles. After mowing my dad's yard I headed back home and it shifted normal. Saturday the AC started blowing hot air. Not ambient air but really hot like the heater was on. I found a place to park and shut if off for about 15 seconds and restarted. The AC was blowing cold again. Seems like both of these issues re-set themselves after the truck was shut off and restarted. Any ideas on where this gremlin is living? Thanks for any help.
