99 S10 4x4 problems HELP

I have a 99 s10 with 51000 mi push button automatic transmission v6 .....My problem is I can't get 2wd or 4lo just 4 auto 4 hi when I press the button for 2wd it blinks I hear the TCCM click and then the encoder motor tries to do something the click back to 4hi same with 4lo ...

check for codes....
Decoder shifter motors are very popular this time of the year. That could be the problem,but you should see if you have any codes stored and go from there..

Only code I got was P0300 multiple cylinder misfire
