First code, happened when i started truck...
P1749 trans throttle valve position sensor circuit low

Cleared with Smarty and test drove it.....stuck in 1st gear (i think) - did another short drive, it does actually shift, just very sluggish.

During above drive, threw these two codes...so i parked it...

P1754 trans throttle valve actuator stuck

P1751 trans throttle valve position min range performance


Mechanical? Electircal? I emailed my trans guy, hoping to hear back from him shortly...but curious if anyone else knows...i'm clueless....
