5r55e won’t shift past 2nd

[Ohhnulix]

02 4.0 4x4. At first I had no drive or reverse (went out on me going down the road), got home slowly, did a fluid and filter change, now I have drive and reverse back but won’t shift past 2nd gear. It’s like it drops out of 2nd to shift and just hits a an almost neutral, it goes but with no power, valve body sticking maybe? Or shift solenoids? I have another transmission I can rip the valve body out of that works fine, the other transmission has other issues but the valve body and stuff should be Almost brand new. When I did the fluid it was almost black, but no sort of metal shavings , no sort of slipping between 1st and 2nd

Valve body loosened...and blew out gasket possibly.

Probably loosened from overheating
