POSSIBLE SHIFT SOLENOID PROBLEM. ARE THERE ANY TRANS CODES?

don't know how to check codes, the mech said, bad tranny, then "$2,000.00 please". but the oil not burned, and still shifts, so I don't trust mechanic...who can I trust? or where can I get codes checked? In Muncie area?

An Autzone or Amco transmission shop in our area advertise the check the codes for free, get a second opinion and post the codes then maybe someone can help. Codes will look like P0420 or P1135.
