HELLO HELLO MY NAME IS WILLIE AND I HAD A ? I BOUGHT A "96" CADI SEDAN DEVILLE FROM A CROOKED CAR DEALER IN OC, CALI! I LOVE THE CAR IVE ALWAYS WANTED ONE OF THESE BUT FROM DAY ONE I HAVE HAD NOTHING BUT PROBLEMS WITH IT THE DEALER SHIP WAS SUPPOST TO FIX IT BUT PULLED A FAST ONE ON ME AND CLOSED DOWN LEAVING ME WITH THE ISSUES TO DEAL WITH MYSELF. SO TO MAKE A LONG STORY SHORT I GOT SOME CODES I WAS WONDERING HOW TO GO ABOUT FIXING THEM! SCANNED WITH (AUTO X RAY EX SCAN 5000) THE CODES ARE P0101-MASS OR VOL AIR FLOW . ALSO P0741- TORQUE CONVERTER CLUTCH CIRCUIT PERFORMANCE OR STUCK OFF! HOW DO I ADDRESS THESE ISSUES ANY HELP WOULD BE GREATLY APPRECIATED! ALSO THE MAIN PROB. IS THAT THE CAR WONT SHIFT INTO 4TH GEAR AT TIMES!

 

I suggest you take the car to a transmission shop for an estimate.

 

I suggest you buy a factory service manual.

 

both Katz, and Carnut gave some good info.... it could be something like a solenoid. not too bad to replace or have replaced. hopefully its that, but a tranny shop would know better. good luck
