NOTE: Check the transmission fluid level before performing any further diagnostics. For more information, refer to: Checking the transmission fluid level (308-03 Manual/Transaxle Transmission, General Procedures).
Symptom | Possible reason | Action |
Significant downshift effort required or synchronizer noise | Check the integrity of the gearshift mechanism and the correct installation. If the timing is incorrect, install a new gearbox. Refer to the new module/component installation note at the top of the DTC Index. | |
While driving, the engaged gear spontaneously turns off | Install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Difficult operation of the gear lever mechanism (tight or partially wedged) | Check and install a new arm bearing if necessary. Check the integrity of the cables and the gearshift mechanism and its correct installation. If an internal failure is suspected, install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Intermittent creaking when shifting gears | Insufficient gear synchronization | Install a new transmission, refer to the new module/component installation note at the top of the DTC Index |
Leakage from the gearbox housing | Check and repair breather leaks, fill/drain ports, seals and clutch hydraulics | |
Clicking noises when shifting into reverse gear | Damage to gear teeth | Install a new transmission, refer to the new module/component installation note at the top of the DTC Index |
Gear grinding when shifting gears | Check and add transmission fluid. Check the correct operation of the clutch. If you suspect a defective selector fork or synchronizer rings, install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Noises in forward gears | Check and add transmission fluid. Make sure the engine/gearbox assembly is not in contact with the chassis/body. Tighten the engine/gearbox flange bolts to the correct torque. For more information, please refer to: Specifications (308-00 Manual Transmission / Transaxle Transmission &Clutch - General Information, Specifications). If you suspect a bad input or output shaft bearing, install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Spontaneous disengagement of gears | Repair or install a new engine/transmission mount. Check the correct installation and adjustment of the gearshift mechanism. If an internal failure is suspected, install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Can't turn on one of the gears (in particular the back) | Check the correct installation and adjustment of the gearshift mechanism. If an internal failure is suspected, install a new transmission, refer to the new module/component installation note at the top of the DTC Index | |
Can't get into 1st and 2nd gear (third, sixth and back work fine) | Broken selector pin in backstage (inside the shift mechanism in the gearbox) | Install a new internal gearshift mechanism (do not install a new gearbox assembly) |
Excessive free play in the shift lever mechanism | Check and install new shift lever bearing and cables if necessary | |
Clutch slip | Check the clutch pedal for sufficient clearance and no binding. Check and, if necessary, install new clutch pressure and drive plates. Check the integrity of the flywheel. Check and, if necessary, install a new slave cylinder | |
Clutch vibration or jerk | Check the integrity of the engine mounts. Check the integrity and absence of contamination of the clutch components. Check the condition of the flywheel. Repair or replace components | |
Clutch sticking (difficult gear shifting) | Check the level and add hydraulic fluid if necessary, check the hydraulic system for leaks. Check clearance and clutch travel. Check the integrity of the clutch, ensure the free movement of the drive disk on the splines of the input shaft | |
Clutch Pedal Pulsation | Check the free play of the clutch pedal on the axle. Check the integrity of the clutch pressure plate, clutch release bearing and flywheel |
