Note: Due to the complexity of the automatic transmission in a garage environment, it is not possible to perform a functional check or repair. For troubleshooting not listed below, the vehicle must be sent to a workshop or automatic transmission specialist.
Transmission fluid leak
- Transmission fluid is usually dark in color. Leaks should not be confused with engine oil, which can be easily carried into the transmission by airflow.
- To determine the source of the leak, remove all dirt from the gearbox housing and surrounding area with steam or a degreaser. Drive the vehicle at low speed so that the air flow does not carry the leaking fluid away from the source of the leak. Raise and support the vehicle and locate the leak.
The most common places for leaks:
- A) Transmission oil pan (Chapters 1 and 7B).
- b) Probe hole (Chapters 1 and 7B).
- V) Transmission cooling water connection pipes (Chapter 1 and 7B).
Transmission fluid is brown or has a burnt odor
- Low transmission fluid or fluid needs to be changed (Chapter 1).
Downshift does not engage when the throttle pedal is fully depressed
- Low transmission fluid (Chapter 1).
- Incorrect gear selector adjustment (Chapter 7B).
The most common malfunctions in the gear shift system
IN chapter 7B describes the procedure for checking and adjusting the gear selector on automatic transmissions.
The most common malfunctions caused by a poorly adjusted selector:
- A) Starting the engine in gears other than "Park" or "Neutral".
- b) The indicator on the selector lever that indicates the gear engaged differs from the actual gear engaged.
- V) The vehicle is moving while the mode is on "Park" or "Neutral".
- G) Incorrect or erratic gear shifting.
Talk to chapter 7B and adjust the gear selector cable.
Engine does not start in three gears, or starts in gears other than Park or Neutral
- Starter interlock switch incorrectly adjusted (Chapter 7B).
- Incorrect adjustment of the selector cable (Chapter 7B).
Transmission slips, noise occurs, or vehicle does not move in forward or reverse gear
- There are many likely causes for the aforementioned problems, but in a garage environment, only one can be checked - the fluid level. Before taking the vehicle to a service station, check the fluid level and condition of the fluid as described in chapter 1. Add or replace fluid as needed. If the problem persists, you should contact a specialist.
