DTC P0751: No. 1 Shift Solenoid Performance: Testing

  1. Turn ignition on. Clear DTC. See CLEARING TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. Start engine and allow it to reach normal operating temperature. Road test vehicle and check for correct upshift speeds and TCC apply. See ROAD TEST under TESTING in overhaul article. After road test, recheck for DTC. If DTC P0751 resets, go to next step. If DTC P0751 does not reset, fault is not present at this time.
  2. Inspect No. 1 shift solenoid operation. See SHIFT SOLENOIDS & TORQUE CONVERTER CLUTCH (TCC) SOLENOID  under COMPONENT TESTING. Replace if necessary. If No. 1 shift solenoid tests okay, go to next step.
  3. Inspect valve body condition. Check for leaks or obstructions in fluid passages. Overhaul if necessary. See VALVE BODY ASSEMBLY under COMPONENT DISASSEMBLY & REASSEMBLY in appropriate overhaul article. If valve body and fluid passages are okay, repair faulty direct clutch.
