8.2.1. Introduction

Because of complexity of an automatic transmission and necessity of use of special adaptations for the majority of operations on service in the given chapter the description of operations of general diagnostics, routine maintenance, adjustment and removal and transmission installation is resulted only.

The transmission represents very difficult unit, and repair it it is necessary to make in a specialised workshop. Before transmission repair it is necessary to define character of malfunction which can be electric, mechanical or hydraulic.

Do not remove a transmission from the car for repair before not will malfunctions as the majority of tests demands that the transmission was in the car are professionally revealed.

The general diagnostics

Indistinct work of an automatic transmission can be caused five principal causes:

 – Unstable work of the engine;
 – Wrong adjustment;
 – Misoperation of hydraulic system;
 – Mechanical damages;
 – Malfunctions in the computer or in its alarm chains.

Diagnostics always should be begun with the most simple checks of level of a liquid and its condition, adjustment of levers of a gear change and management throttle заслонкой. Then it is necessary to make a control trip for that definition, whether the problem is eliminated or additional diagnostics is required. More detailed diagnostics should be made at servicing deport.

The preliminary control

1. Make a control trip on distance some kilometres for transmission warming up.
2. Check up liquid level. If level of a liquid below norm, add a liquid to the necessary level, and then check up on presence of leaks. If level too high, merge superfluous quantity of a liquid, and then check up the merged liquid on presence in it a cooling liquid. Presence of a cooling liquid from the engine in an automatic transmission specifies in malfunction in internal walls of a radiator which separate a cooling liquid from трансмиссионной. If the liquid in a transmission is made foam, merge it and fill in in a transmission a new liquid, and then check up presence in трансмиссионной a liquid cooling liquids.
3. Check up turns of idling of the engine.
4. Check up a cable of management throttle заслонкой on course freedom. If it is necessary, adjust it.
