Rebuild tranny but im really not trusting the mechanic

For P1738, possible 2nd clutch pressure switch failure , or it's unplugged , or wire damage. Also could be TCM , but if TCM wasn't bad prior to rebuild I'd go there last. P0740 is torque converter clutch circuit problem . Is this a trans shop that did the rebuild , and how long ago (time/miles) was it rebuilt?

possible incorrect grade of fluid used. it would throw off sensors and effect performance. also agree with ziptie.
