My crossfire entered limp mode after driving down a main rd and the rear tires locking up. I spun and almost crashed, luckily I corrected the tires, and pulled off the side of the rd. I was stuck in 1st gear but was able to make it home. The code I got was the speed sensor and secondary air intake? I replace the conductor plate with an original oem part that had 50k miles. Got the correct trans fluid level, and reset the computer with the battery terminal trick. Tried driving, still in first gear, the engine light on. Anyone have a clue?

 

How did you check fluid level?
WHAT CODES ON THE OBD II ???? Exact codes, not your interpretations
What is a "Double 04 crossfire" ?
When your "rear tires locked" what were you doing with the transmission???????? Downshifting maybe?
If you got "speed sensor and secondary air intake" codes, why change the conductor plate?? especially with a used one of unknown quality?

 

Po175 I believe for speed sensor, and I値l re do for the secondary code. I wasn稚 doing anything to the transmission but crusing in drive. (004 is 2004) I checked fluid level with a dip stick I bought and made marks on myself.

Dip stick level.

 

Perhaps P0715? Probably heading in the right direction.
Did you clear codes after your plate switch ? I read you disconnected battery, but did you check to see codes cleared before starting car?
Was there trans fluid on the electrical connection when you first got under the car and unplugged it? That fluid can wick up the cable to the TCM.
You can get a new OE trans plate here for reasonable price, click: conductor plate
