Hard shifting after 1-2 hours driving.
Hello new to powerstrokes in general and my overdrive light has been blinking and the truck has been shifting hard from 1-2 2-3 it also only shifts when it gets near the red line at about 3800 rpm after driving for about 1-2 hours. I believe it skips second. When the transmission cools and i restart the truck the truck seems to run fine no hard shifting. I have scanned the codes and they are p0782 p0781 p0732 p1247. I was wondering if it will need a complete overhaul or if if the problem is something I can fix.
Things I've Tried:
-Checked chafing on the shifter.
-Checked correct fluid level
-Smells and looks like new transmission fluid.
My truck is a 2002 F450 with the 4r100 transmission. 4wd.
