Ford Edge service bulletins

Ford Edge transmission problems

If you own a 2007 Ford Edge or 2007 Lincoln MKX and have Ford Edge transmission problems like a harsh shift, no upshift, or have fifth gear only, refer to this Ford Edge service bulletins #07-3-11. The Ford Edge service bulletin addresses trouble codes P0715, P0717, P0718, P0720, P0721, P0722 as well as the symptoms listed above.


P0715 Input/Turbine Speed Sensor Circuit Malfunction

P0717 Input/Turbine Speed Sensor Circuit No Signal

P0718 Input/Turbine Speed Sensor Circuit Intermittent


P0720 Output Speed Sensor Circuit Malfunction

P0721 Output Speed Sensor Range/Performance

P0722 Output Speed Sensor No Signal


The Ford Edge service bulletin applies only to SOME 2007 Ford Edge and Lincoln MKX vehicles equipped with the 6F50 transaxle and built BEFORE 1/1/2007. Ford has determined that these Ford Edge transmission problems may be the result of a short in the output shaft speed sensor (OSS) or the Turban shaft sensor (TSS).


The service bulletin recommends following all the normal testing procedures listed in the shop manual. If you find the proper voltages and the wiring harness is in good condition, replace the sensors with updated units.


The new parts are

7T4Z-7M101-A TSS

7T4Z-7H103-B OSS


The TSS sensor is located in the end cover assembly. The OSS is inside the transmission under the main control. Both sensors look identical but they are not interchangeable as they are wired differently internally.


If the vehicle still exhibits a harsh driveline clunk during low speed (below 10-MPH) on tip-in acceleration, or the vehicles rolls on an incline while stopped without the brake applied while in drive or reverse, reprogram the PCM as Ford service bulleting 08-26-8.


Ford dealers and some independent shops can perform the software update. It is not free and generally runs less that $200
