Greetings! Have a 2004 GC, 4.0 with the 42RE trans. Check engine light went on recently and noticed it was sluggish and swallowing gas. Code was a PO753, transmission shift solenoid. I dropped the pan and replaced the governor pressure solenoid and trans pressure sensor. Put in a fresh filter and ATF+4 fluid. Results are the same; check engine light still on, sluggish, etc. Could it be an electrical issue and if so what? How to further test or diagnose? Thanks for your input.
