Your VSS (Vehicle speed sensor) might be out and the transmission isn't shifting right and your engine might be running rich or lean as a result therefore also sending out a O2 sensor fault codes. Deosnt mean your O2's are bad.

Sounds like Idle Air Control (IAC) valve, throttle body needs to be cleaned, or it could be a internal transmission failure causing just the 1 gear to lockup. No one can really help you unless you post your truck specifications.

ok im going to try to clean iac but heres an odd note my od light on shifter is blinking is that normal never payed any attention to that light

That means internal transmission failure. I would say you clutch plates are worn. It will probably need to b rebuilt in the near feature.

well that sucks but would that cause my drive and reverse to make motor run like crap?

If the clutch plates on the torque convertor are shot, it will cause a misfire like feeling. Check IAC and IAC connector first.

think I could get away with just changing torque converter? or should I just pull a junkyard trans a rebuild is not happening.....I traded a 4x4 chevy 1500 with a blown hard to find trans..

Yea, but I would definitely check everything over. Something caused that trans to fail whether it be clogged lines, bad trans cooler (if you own a 4x4) or you been going 70 and dropping it in 2nd.

If that OD light is flashing, you have a code stored in the OBD II system. It may not show to these android based readers everyone has been using, but a real scanner can read ford codes that the tranny produces. The OD flashing is the Check Engine Light of the truck.
