ok so let’s start, this morning i went out and started up the Expedition which is what i normally daily drive. Everything was fine until i put it in reverse my engine was surging very noticeably to the point the truck was shaking..... fast forward i get out to the road and my engine is surging through the entire rpm range, this is when i realize it’s not the 5.4 acting up, i can actually hear my torque converter engaging and dissengaging down the road, pull over hit O/D off and lock out gears 5&6. Now it still jumps and surges accelerating and at idle in gear. Opinions, Replace tranny, Fluid flush?? The torque converter is engagunga and disengaging rapidly while i drive down the road making the truck drive and transfer power horridly. My shop wants to throw a tranny at it. Not so sure. Basically to simplify it the truck shakes when accelerating and in overdrive but i can tell this is the torque converter. I posted about this truck starting to act up in a different thread but today these symptoms are new and i have to act swiftly.
