I have a 2004 f350 6.0 with 175,000 on it. Started having issues with it shifting and the tow haul blinking it through codes for solenoid b and eventually all the solenoids. just recently replaced all 7 solenoids in the transmission along with both filters. unfortunately I'm still having the same issues. It seems as though the warmer it gets the worse it gets. Symptoms include hesitation when shifting into gears from Park. Sometimes will not move in reverse x as if it's fighting itself, surging and shuddering while driving, erratic shifting and extreme lack of power. I'm no Master mechanic by any means and being that it's my daily driver this issue is getting pretty frustrating any help would be greatly appreciated.
