trans slipping?

06 f250 6.0l

Been having this issue with my trans here and there. While driving from a stop, it'll shift fine through the gears. Other times, it'll shift 1-2 fine (or 1-3), can't remember, but first 2 (or 3) gears will shift firmly, then it feels like it slips into the next. Trans fluid is bright red still, made sure of that when I had my cab off for head studs and gaskets. Nothing smells burnt. No codes. 77000 on it, but to my knowledge it has never had a trans flush or filter internal or external. I'm planning on dropping the pan this weekend and putting a new internal and external filters. Should I get it flushed after this? Or is there something else I can look at as to why this is happening?

Try new fluid first.

No need to change the internal pick-up.... It isn't a filter. Just clean the magnet.

About 8 quarts for a dump and fill.

Mercon SP or LV only.

If you wanted to be hard core. You could buy the internal filter for a 2008+. Ive heard they updated them with filter media inside. Other then that they are the same.

You have to use the 08+ pan with the 08+ filter
