Check of linear pressure

The purpose of this test is check of working conditions of each part by means of measurement of pressure of a liquid on a line of pressure of a liquid. Following conditions are necessary for performance of the test of linear pressure:

The liquid of an automatic box has normal working temperature (70-80 C/158 – 176F).

The liquid is filled to demanded level (between marks on probeе COMPLETELY HEATED-UP and "not HEATED-UP").

1 — an aperture for check of pressure of a liquid
2 — the pallet картера

 PERFORMANCE ORDER

  1. Reliably put on a lay brake and put to wheels the verifying device.
  2. Attach the device for measurement of pressure of a liquid to an aperture for check of pressure of a liquid in the transmission case. The special tool (A): 09925-37810.

Having attached the device for check of pressure of a liquid, check up, that there was no liquid leak.


1 — the pallet картера
2 — an exhaust pipe
  1. Press up to the end a brake pedal, include idling of the engine and limiting, and then check up pressure of a liquid in position “D” or “R”.

Do not leave the engine to work on speed limit more than 5 seconds.

Results of check

The possible reason

Linear pressure above standard level in each position

* The faulty valve of a regulator

* The faulty valve of a throttle

* The cable of a throttle of an automatic transmission is not adjusted

Linear pressure below standard level in each position

* Faulty coupling of raising transfer

* The faulty oil pump

* The faulty valve of a throttle

* The faulty valve of a regulator

* The cable of a throttle of an automatic transmission is not adjusted

Linear pressure below standard level only in position “D”

* Leak of a liquid from direct coupling

* Faulty coupling of raising transfer

* Leak in a chain of pressure of a liquid in position “D”

Linear pressure below standard level only in position “R”

* Leak of a liquid from direct coupling

* Faulty coupling of raising transfer

* Leak of a liquid from a backing brake

* Leak in a chain of pressure of a liquid in position “R”

The moment of an inhaling of a stopper of the case of a transmission: 17 Н•м (1.7 kg th, 12.0 pounds-foots).
