Repair of automatic transmission in Honda
- Written by: News Company
Even in spite of the Japanese brand reliability, repair of the Honda Accord is an inevitable procedure if the mileage exceeded 150-200 thousand kilometres. Probably, problems with the box will begin earlier if the operating conditions were close to extreme.
No repair is impossible without knowledge of the subject of the repair itself. Honda's automatic transmission has its own subtleties, especially 10–20 years ago. In our article, we will talk about them in detail, as well as give practical recommendations for extending the life of the box.
Typical Honda Automatic Failures
Repair of the Honda automatic transmission includes a set of works related to the elimination of malfunctions that appear during the operation of the unit. All kinds of breakdowns of automatic transmissions can be grouped according to the following criteria:
Malfunction of a lever arm. In the automatic transmission of previous generations, the transmission is connected to the selector by a mechanical link, which often fails. As a result of such a malfunction, the ability to change the operating modes of the box is lost. The presence of this problem is indicated by the difficult movement of the automatic transmission lever, which can generally jam in one position. In some models of automatic gearboxes, backstage repairs are performed without removing the unit, which significantly speeds up and reduces the cost of work.
Oil leak. The flow of gear oil is a fairly common malfunction of the Honda automatic transmission. Smudges may appear in the area of gaskets and sealing elements. To diagnose this malfunction, it is necessary to inspect the unit by hanging the machine on a lift. Elimination of the causes of oil leakage from the automatic transmission must be performed by qualified specialists. In this case, the repair of the automatic transmission includes the replacement of gaskets and seals, as well as adding fluid to the required level.
Transmission Control Unit (CU). Often the automatic transmission "Honda" fails the electronic control unit. As a result of such a breakdown, the box will incorrectly select the operating mode and may be completely blocked. Automatic transmission repair in such a situation is associated with the replacement of control loops and/or faulty control unit elements.
Signs of a breakdown of the automatic gearbox are jerks when driving on a heated automatic transmission, which is when a manual gearbox specialist can help diagnose and resolve the issue. The lack of reverse gear is also a consequence of a malfunction of the valve body. This is due to the pressure drop due to mechanical wear of the parts. The machine cannot go back, because the necessary pressure is not created in the automatic transmission.
As a result of a malfunction in the hydraulics, wear of the clutches and steel discs occur. During the repair, these parts will need to be replaced.
During the repair of the automatic transmission of a Honda car, after the hydraulic unit breaks, the hydraulic plate must be replaced with a new original part. All components of Honda automatic machines are detailed separately, but not all spare parts are constantly available. Many parts are delivered to order, which requires a certain amount of time.
To avoid the premature repair of the Honda automatic transmission, you should not attach a trailer to your car or take other cars into tow. In addition, it is impossible to tow a car with an automatic transmission with the engine turned off. It is better if the faulty car is delivered to a car service on a tow truck.
When this is not possible, a non-working car with automatic transmission should be towed with the engine running at a speed of no more than 30 km / h. In this case, the gear lever must be set to position N.
In order for the Honda automatic transmission to last longer, you should not start abruptly, starting off. For an automatic box, such starts are very harmful.
