Did a little work on the transmission today. Did a shift kit, filter, and changed all the fluid. Now the truck is at least drivable. Before it would slip in 2nd to 3rd and 3rd to 4th. Now the 3rd to 4th is completely fixed and doesn’t slip at all. But the 2nd to 3rd is still doing it. This is telling me it’s got to be something that just needs to be adjusted now but that’s just my guess. It’s not a really bad shift either. Slips for about half a second then kicks right into 3rd. Also when dropping the pan it was pretty clean. No chunks of anything in it
