Note: Due to the complexity of the AT design, it is advisable to carry out diagnostics of its malfunctions and repair of components in a car service workshop.
57. General problems associated with the functioning of the switching mechanism
1. The number of failures associated with a violation of the adjustment of the shift rod includes the following
- The engine can be started in transmission positions other than R and LH.
- The transmission position indicator reading is different from the actual gear selected;
- The vehicle is moving in transmission. set to position P or N;
- Transfers are switched with difficulty or arbitrarily.
2. Adjust the shift rod
58. Transmission slips, shifts hard, makes strange noises or does not move the car when set to one of the gears
1. There are many possible causes for the problems listed in the title, but only one of them falls under the competence of an amateur mechanic - the wrong level of transmission fluid (ATF).
2. Before driving the car to a car service workshop, check the ATF level and condition. Correct the ATF level or change it.
59. Transmission fluid leaks (ATF)
1. ATF is dark red in color. Traces of its leaks should not be confused with traces of impellent oil, which can be carried to the transmission crankcase by the oncoming air flow.
2. To identify and locate the source of the leak, first remove all traces of dirt and grease from the transmission boat. Use a suitable degreaser and/or steam clean. Then drive the car for a short trip at low speed (so that traces of the leak are not carried away by the oncoming flow far from its source). Stop, jack up the vehicle and locate the source of the leak by visual inspection. Most often these are:
- Transmission oil pan - Tighten mounting bolts and/or replace oil pan gasket;
- ATF fill tube - replace the rubber seal where the tube enters the transmission case;
- ATF lines - tighten unions or replace lines;
- Vent Tube - Transmission is overfilled and/or has water in it.
60. ATF is brown or burnt
1. Insufficient ATF level.
61. Kickdown mode does not turn on when you fully press the pedal (no downshift)
1. Dropped ATF level.
2. Faulty engine management system.
3. Faulty sensor-switch or its electrical wiring.
4. Adjustment of a drive cable of the selector is broken.
62. The engine does not start at any position of the selector or starts in positions other than «R» And «R»
1. The adjustment of the start enable sensor-switch is broken.
2. Serviceability of functioning of a control system of the engine is broken.
3. Adjustment of a cable of the selector is broken.
63. Transmission slips, jerks or noises when shifting gears. The car does not move when the modes are turned on «D» or «R»
1. Dropped ATF level.
2. Faulty sensor or wiring.
3. Serviceability of functioning of a control system of the engine is broken.
