I have a 04 6.0 and my transmission is acting funny. Sometimes when I go to accelerate it feels like the parking brake is set and isnt allowing full power. Also hard to accelerate up inclines. While cruising around 55-60 mph transmission will down whift without warning then immediately shift back up. I'm having a lot of vibration when in reverse and it seems like it has a delay when sifting into reverse.
