I was told to try the ignition switch harnes, and that also did not fix my problems. I have no gauges,(only alt, and oil pressure), and it feels like i am stuck in 2nd gear, and there seems to be no power to go at all. Could it be my computer needs to be flashed or maybe a relay i don't know about? Please Help. Thanx

Clear codes and see which one comes back first.
Your codes you have now are 4 different solenoids or solenoids circuit problems.
4 codes together is more wiring/power/ground problems.
If all 4 codes come back check transmission valve body solenoids wiring and power and grounds.
Also check fuse and fuse box power feed.
And check transmission range switch wiring and plug in and power feed.
