Damage to the transmission range switch | Damage to the transmission range switch |
No communication with the scanner HI - SCAN If no communication with the scanner HI - SCAN, may be defective or electric circuit is not functioning TCM | Damage to the electrical circuit Damage to the connector Damage TCM |
| Unable movement | Can not start the engine Can not start the engine when the selector lever is in position N or P. In such cases, the cause may be a malfunction of the engine control, the torque converter or oil pump. | Damage to the engine management system Damage to the torque converter Damage to the oil pump |
No progress If
there is no forward movement when moving the selector lever from N to D, 3, 2 or L when the engine is idling the reason, perhaps in abnormal pressure in the pipeline or damage downshift or valve body. | Abnormal line pressure Damage to the solenoid valve to downshift Damage to clutch downshift Damage to the valve body |
No reversing If
there is no movement
reverse by moving the selector lever from N to R position when the engine is idling the reason, perhaps in abnormal pressure in the reverse gear clutch, brake and transmission lowest reverse gear or valve body. | Abnormal pressure in the clutch reverse gear Abnormal low pressure in the low-brake transmission and reverse gear Damage to the low clutch transmission and reverse gear Damage to the valve body |
There is no movement forward or backward If there is no movement
forward or back by moving the selector lever from the N position to any position when the engine is idling the reason, perhaps in abnormal pressure in the pipeline, damage to the transmission, oil pump or valve body. | Abnormal line pressure Damage to the gearbox Damage to the oil pump Damage to the valve body |
| Failed to start | Stopping the engine at the beginning of movement If the engine stops when you move the selector lever out of position N to D or R when the engine is idling the reason perhaps damage the engine management system, damper clutch solenoid valve, valve body or torque converter | Damage to the engine management system Damage to the damper clutch solenoid valve Damage to the valve body Damage to the torque converter |
Jerks or delayed response when you move the selector lever out of position N to D If there are jerks or there is a delay of more than 2 seconds when moving the selector lever from N to D when the engine is idling the reason, perhaps, in damage downshift, pressure or clutch downshift valve body or the position switch | Abnormal pressure to downshift Abnormal low pressure in the low-brake transmission and reverse gear Damage to the solenoid valve to downshift Damage to the valve body Damage to the position switch |
Jerks or delayed response when you move the selector lever out of position N to R If there are jerks or there is a delay of more than 2 seconds when moving the selector lever from N to R at the engine idling reason, perhaps in abnormal pressure coupling the reverse gear and the back pressure in the brake system, clutch reverse, brake, low transfer and reverse gear, the valve body or the position switch | Abnormal pressure in reverse clutch Abnormal low pressure in the low-brake transmission and reverse gear Damage to the solenoid valve of low transmission and reverse gear Damage to the reverse clutch Damage to the valve body Damage to the position switch |
Jerks or very slow response when moving the selector lever from N to D, N or R If there are jerks or there is a delay of more than 2 seconds when moving the selector lever from N to D or from N to R position when the engine is idling the reason, perhaps in abnormal pressure in the pipe or damage the oil pump or valve body. | Jerks or very slow response when moving the selector lever from N to D, N or R If there are jerks or there is a delay of more than 2 seconds when moving the selector lever from N to D or from N to R position when the engine is idling the reason, perhaps in abnormal pressure in the pipe or damage the oil pump or valve body. |
| Failure displacement | Jerks and omissions If there is jerking motion during the displacement of the selector lever and the transmission is switched higher than the engine speed is the reason, possibly in abnormal pressure in the pipeline is damaged or solenoid valve, the oil pump, the valve body, the brake or clutch. | Abnormal line pressure Damage to each solenoid valve Damage to the oil pump Damage to the valve body Damage to each brake or clutch |
| Changes of position movement | All provisions If the motion displaced all
transfer position reason may be damaged in the speed sensor of the driven shaft, TPS or solenoid valve. | Damaged throttle sensor Damage to each solenoid valve Abnormal line pressure Damage to the valve body |
Some provisions If at some offset movement
transfer position reason possibly damage the valve body | Damage to the valve body |
| No offset | There are no diagnostic trouble codes If the motion is no offset and diagnostic codes reason possibly damage the transmission range switch and TCM | Damage to the transmission range switch Damage to the valve body |
| Failures movement | Poor acceleration If vehicle acceleration is weak, even if a forced downshifting, the reason may be damaged in the engine control, the brake or clutch. | Damage to the engine management system Damage to the brake or clutch |
Damage to the engine management system Damage to the brake or clutch | Damage to the engine management system Damage to the brake or clutch |
Switch the transmission range The reason, perhaps, to damage the circuit breaker lockout, ignition or TCM | Damage to the ignition |
Vehicle Speed Sensor The reason may be damaged in the sensor circuit
