Good Evening Everyone,
I'm going to try to make this post as detailed as possible so I don't miss anything.
I recently purchased a 2008 Explorer 4.0L Eddie Bauer Edition with a known blown head gasket. I've since replaced the head gaskets (and the heads) reassembled everything and have found it also has transmission issues (yay!). When I was rebuilding the engine I replaced the radiator, so I lost a little transmission fluid when I removed it. After replacing the radiator one of the cooler lines going into the radiator developed a leak so I had to replace that. I ordered a replacement line from Rock Auto and cut the existing line, and put the flexi rubber hose in it's place. Got everything hooked back up, got the car up to temp and topped off the fluid. Went through each gear just in case the PCM needed to relearn anything. Immediately noticed hard shifting into reverse and a slight jolt when shifting into D. I figured this may be the transmission relearning everything so I took it for a test drive. Once in reverse, it works wonderfully, no slipping, just the initial hard shift. Then I shift into drive, it seems like it's stuck in 3rd gear (limp mode?) and won't even attempt 1st or 2nd. I can't even get it to manual shift into 1st or 2nd (can manual shift into 3rd no problem) to keep the car moving at speed it feels like I have to have the pedal depressed fully, if I fully depress the pedal the power kicks (if at or above normal 3rd gear operating rpms). I do have a slew of codes I was able to pull.

Perhaps it could be the solenoid pack? Fluid flush/fill? Valve body? External Solenoids?
I don't want to start dumping money into replacing things that don't need replaced. Car has 204k miles on it, and it LOOKS like the trans has been replaced at some point so I'm going to hazard a guess that the transmission may have more or fewer miles on it.
Any/all help is appreciated!
