                                                     CHECKING THE SOLENOIDS

 

   Solenoids can be checked with an ohmmeter separately or directly on the car plugs with

TCM. Watch this page - preparation. We use the shot battery and wires with "crocodiles".

   When voltage is applied to the solenoid occurs electromagnetic field, which attracts a

microparticle metal in oil. They accumulate in the body coil, which leads to jamming or plun-

ger ball valve malfunction. Furthermore, the presence of metallic microparticles in the oil have

contributed to congestion in the channels. Some solenoids can be disassembled, washed. This

solenoid "NEUTRAL IDLE/TCC ON - OFF SOLENOID VALVE". Inside the coil is a core with a

"nose", which is connected to a ball valve. "Nose" should be length 3.8 mm and a diameter of

1.3 mm. If it does not meet the length or flattened, the it should be replaced by a solid

metal. Mean only the "nose" refer to the turner.

   Scan channels the other two solenoids and ball valves can be accomplished using comp-

ressed air. It should be remembered solenoids may be normally open and normally closed.

Solenoid "NEUTRAL IDLE/TCC CLUTCH CONTROL SOLENOID VALVE" when voltage is applied to

the coil is open. Air must not pass through the outlet solenoid. In the absence of voltage on

the winding ball valve is open. Air must pass. This solenoid hydraulic valve body is screwed to

the main body. On this there is a volume adjustment drain ball valve by loosening antighte-

ning the body of hydraulic valve. Ie ball valve is to create pressure (by closing oil drain) to

compress the clutch, but also quickly depressurized to turn off clutches. Otherwise they will

burn quickly.

   In the body of the hydraulic valve has a small hole - a jet. Nozzle creates a resistance to

the flow of oil, thus reducing the rate of filling of butter oil channels. Smooth grip clutches.

   Solenoid "LINE PRESSURE CONTROL SOLENOID VALVE" when voltage is applied to the coil is

open. Air must pass through the outlet solenoid. In the absence of voltage on the winding

ball valve is closed. Air should not pass. Here, too, have adjustable volume flush ball valve.
