I had a bad overdrive solenoid in the trans, so I replaced it. While I was at it I changed the filters, and solenoid body gaskets. I did not do a flush since one was done fairly recently. I put it back together, added 12 fresh quarts of Mercon LV, now it does nothing but rev like it’s in neutral in every gear. Drained the fluid, dropped the pan to make sure I didn’t forget to plug something in, everything was as it should be. Filled it up again and still nothing. Any ideas? 2005 F250 6.0 4x4 with 165k mi.
