| P0123 | TP concern | ||
| P0300-P0308 | El system has a malfunction which may cause a transmission concern. Harsh engagements and shifts, late WOT shifts, no torque converter clutch engagement. | ||
| P0320 | El System | ||
| P0340 | El System | ||
| P0500 | Torque converter clutch engages, shift engagement I disengagement (hunting) on grades. | ||
| P0501 | Torque converter clutch engages, shift engagement I disengagement (hunting) on grades. | ||
| P0503 | Insufficient VSS | ||
| P0741 | Torque Converter Clutch Control Circuit Low | ||
| P0743 | Torque Converter Clutch Control Circuit Low (2) | ||
| P0750 | SS1 solenoid circuit failed to provide voltage drop across solenoid. Circuit open or shorted or PCM driver failure during on-board diagnostic. | ||
| P0755 | SS2 solenoid circuit failed to provide voltage drop across solenoid. Circuit open or shorted or PCM driver failure during on-board diagnostic. | ||
| P0781 | Improper gear selection depending on failure or mode and manual lever position. Shift errors may also be due to other internal transmission concerns. | ||
| P0782 | Improper gear selection depending on failure or mode and manual lever position. Shift errors may also be due to other internal transmission concerns. | ||
| P0783 | Improper gear selection depending on failure or mode and manual lever position. Shift errors may also be due to other internal transmission concerns. | ||
| P1100 | El system has a malfunction which may cause a transmission concern. Incorrect torque converter clutch engagement scheduling. | ||
| P1101 | El System | ||
| P1116 | ECT out of on-board diagnostic range | ||
| P1117 | Intermittent ECT signal to PCM | ||
| P1124 | TP voltage high /low | ||
| P1351-P1364 | El system has a malfunction which may cause a transmission concern. Harsh engagements and shifts, late WOT shifts, no torque converter clutch engagement. | ||
| P1460 | A/C clutch cycling may result from AIC clutch pressure switch error. | ||
| P1703 | BOO switch circuit failure. Brake not actuated during on-board diagnostic. | ||
| P1740 | TCC malfunction. Engine stalls in 2nd (0 I D 2 Ranges) at low idle speeds with brake applied. | ||
| P1741 | Torque Converter Clutch Control Circuit High | ||
| P1742 | Torque Converter Clutch Control Circuit High (2) | ||
| P1743 | Torque Converter Clutch Control Circuit High (3) | ||
| P1744 | Torque Converter Clutch Control Circuit Low (3) | ||
| P1746 | TCIL circuit failure. EPC solenoid circuit failure, shorted circuit or output driver. Shorted PCM output driver. | ||
| P1747 | TCIL circuit open or shorted. Voltage drop across TCIL exceeds scale set for temperature 12s•c (254°F). Torque converter clutch will always be off, resulting in reduced fuel economy. | ||
| P1767 | TCC solenoid circuit fails to provide voltage drop across solenoid. Circuit open or shorted or PCM driver failure during OBD test. |
