Alright, maybe someone can help me out here, 2000 expedition,Eddie Bauer, 140K, 5.4. Gone thru all the usual diagnostics, no coil issue, no codes. When the A/C is on and the engine is under a load, mainly up-hill, it feels like the tranny is slipping and there is a severe loss of power. When the A/C is off. Not a single problem in the world. cannot understand it. Had a 92 Explorer with 2 transmissions in it, nevereven came close to acting like this. Any insight on this would be greatly appreciated before I go dropping money into it. My baby's hurtin!
