Cadillac Repair: 99 deville transmission, torque converter clutch, torque converter clutch solenoid

Question
QUESTION: Computer code P0741 and P1527  No symptons,  Only "SERVICE ENGINE SOON" annunicator.  After clearing the code, the annunciator came back on after 1 year and 6,000 miles.  Could it possibly be a computer sensor error?  Please advise.  Thank you.  

Answer
P0741 is a fault of the overdrive circuit in the transmission. Most likely a faulty TORQUE CONVERTER CLUTCH SOLENOID.

P1527 is a fault in the TRANSAXLE (transmission) Range switch and or in the circuit board pressure switches.
