He did not specify which solenoid it may be

I bought this car recently and was told by the seller that the transmission was rebuilt at 90,000 miles and the transmission light will start flashing occasionally while drive at highway speeds because of a solenoid in the transmission. The car still performs normally when the light starts flashing, but I would like to fix it to avoid any problems down the road. He did not specify which solenoid it may be so I am wondering if anyone has a good idea as to what is going on and how serious it is and also on how to fix it? I would like to do the work myself, but my knowledge is limited.

Thank you all very much.

P0741 Code - Check out the diagrams (Below).

Torque converter clutch not engaging when commanded and/or Diagnostic Trouble Codes (DTC) P0741 or P1744 stored in memory.

ACTION

Use a scan tool (NGS/WDS) to monitor PID's to help determine steps to take for service. Refer to the following Diagnostic Procedure for details.

1. For DTC P0741 and P1744, perform Pinpoint test "C" in Section 307-01 of the appropriate Taurus/Sable, Windstar or Continental Workshop Manual and refer to TCC Solenoid Resistance Chart (Figure 1) for correct TCC resistance.

2. Also refer to "Diagnosis by Symptom" Routines 240 and 340 in Section 307-01 of the appropriate Taurus/Sable, Windstar or Continental Workshop Manual.

3. Remove lower pan of the transaxle and check for excessive debris in the pan.

4. Remove the main control cover, main control and pump shaft.

5. Check for pump shaft wear or damaged seals.

6. Inspect the internal wiring harness for damage.

7. Inspect and clean the main control and make sure all valves move freely. Specifically, converter regulator valve, solenoid regulator valve, bypass clutch control valve or pressure fail-safe valve (refer to Figure 2 for Ax4N and Figure 3 for Ax4S).

8. Measure depth of groove in the pump bore ring (Figure 4).

9. If cause for condition has not yet been identified, remove the transaxle and inspect the outer surface of the stator support for damage (Figure 5).

10. Inspect torque converter hub bushing for wear.

11. Inspect turbine shaft seals.

12. To verify the condition has been corrected, the drive cycle must be performed at least five (5) times (for drive cycle procedure refer to the appropriate Workshop Manual Section 307-01). The PCM will not set a torque converter clutch code until it fails to engage five (5) consecutive times.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
