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 |
|
|
- Reliably put on a lay brake and put to wheels the verifying device.
- 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 |
- 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”
