Well the check engine light came on Friday when I was back into the garage. Did not think anything of it so today brought the scanner out to see what was wrong. Started her up check engine light was still on when to put it in first gear the car did not move gave it gas it started to stall up but still no movement. Finally when about 1/4 to 1/2 throttle and it pushed it self out of the garage very unwillingly. Tried reverse which seem to work fine. So what I did to make sure it was the tranny was put the car on jackstands and take off the drive shaft. Tried once again to put it in a forward gear with no drive shaft off with the same result started to stall up and was generally straining to spin the tail shaft. Also here are the trouble codes there where some more but cleared them to see which ones would show up again. Also the setup is a 5.3 backed with a 4l60E with a 3000 stall.

Rev it up to about 5000 RPM in neutral and downshift it into drive. that will make things loose.

I'd follow the evident electrical nature of these
trans faults - start w/ connector inspect, pull &
seat? Any chance recent work could have nicked
the trans harness?

I agree with jimmyblue, start checking electrical connectors, with so many codes at once I'd start at the main harnass in the engine compartment-you might want to get a can of electrical connector/parts cleaner and blast each connector out.

Hopefully this helps.

Okay I will try to clean out all of the connectors today and inspect the harness. I will keep yall posted.
