Automatic Transmission/transaxle: Maintenance Jaguar X-type I рестайлинг

Transmission Fluid Temperature (TFT) Sensor

The TFT sensor is installed in the transmission case, it constantly monitors the fluid temperature resistance varies with fluid temperature.

Automatic transmission internal operational resistance varies with automatic transmission fluid temperature change. The TCM detects the automatic transmission fluid temperature according to the voltage produced by the TFT sensor.

Check Fluid Level and Condition

Note. The transmission oil temperature must not be allowed to exceed 40°C while checking level. Should the temperature rise above this figure, abort the check and allow the transmission oil to cool to below 30°C.

This vehicle is not equipped with a fluid level indicator. An incorrect level may affect the transmission operation and could result in transmission damage. To correctly check and add fluid to the transmission, refer to Transmission Fluid Level Check - General Procedures .

High Fluid Level

A fluid level that is too high may cause the fluid to become aerated due to the churning action of the rotating internal parts. This will cause erratic control pressure, foaming, loss of fluid from the vent tube and possible transmission damage. If an overfill reading is indicated, refer to Transmission Fluid Drain and Refill - General Procedures .

Low Fluid Level

A low fluid level could result in poor transmission engagement, slipping, or damage. This could also indicate a leak in one of the transmission seals or gaskets. Refer to Transmission Fluid Level Check - General Procedures .

Adding Fluid

If fluid needs to be added, add fluid in 0.50 liter increments through the fill hole opening. Do not overfill the fluid. For fluid type, refer to the General Specifications . Refer to Transmission Fluid Level Check - General Procedures .

Fluid Condition Check

1. Check the fluid level. For additional information, refer to «Transmission Fluid Drain and Refill - General Procedures»(ref-311854-S18302283522009040700000) .
2. Observe the color and the odor. The color under normal circumstances should be reddish, not brown or black.
3. Allow the fluid to drip onto a facial tissue and examine the stain.
4. If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.

Note. Being thermostatically controlled, the lubrication system cannot be completely flushed. In the event of a transmission unit replacement for internal failure, the oil cooler and pipes must also be replaced.

Transmission Fluid Drain and Refill - General Procedures

Drain

Scheme 73

1. Raise and support the vehicle. For additional information, refer to «Lifting»(ref-311833) article.
2. Place a suitable container under the transmission drain plug.
3. Remove the transmission drain plug.
4. Install the transmission drain plug. Tighten to 45 Nm.

Refill

Scheme 74

1. Lower the vehicle.
2. Remove the automatic transmission fluid charging pipe cap.
3. Fill the automatic transmission with 8 liters of automatic transmission fluid through the automatic transmission fluid charging pipe.
4. Carry out a fluid level check and adjustment. For additional information, refer to «Transmission Fluid Level Check»(ref-311854-S38871621642009040700000) .

Scheme 75

1. Raise and support the vehicle. For additional information, refer to «Jacking and Lifting»(ref-311833) article. .
2. Connect the Jaguar Approved Diagnostic System.
3. Make sure J-Gate shift selector is in the Park position (P).
4. With the engine running and the foot brake applied, move the J-Gate shift selector through "P-R-N-D-4-3-2" and back to the "P" position to circulate the automatic transmission fluid until the temperature reaches 30 to 40°C (86 to 104°F) on the Jaguar Approved Diagnostic System.
5. When the automatic transmission fluid temperature reaches 35°C (95°F) check that the selector lever is in the "P" position raise the vehicle.
6. With the engine running, remove the automatic transmission fluid level tube plug. Remove and discard the level plug and sealing washer.
7. If the automatic transmission fluid does not come out of the transmission fluid level tube the automatic transmission fluid level is insufficient. If this is the case add the automatic transmission fluid in 0.5 liter units into the automatic transmission fluid charging pipe until the automatic transmission fluid comes out of the automatic transmission fluid level tube. Remove the automatic transmission fluid charging pipe cap.
8. Allow the automatic transmission fluid to come out of the automatic transmission fluid level tube until the overflow stops at a temperature of no more than 40°C (104°F).
9. If when the automatic transmission fluid level plug is first removed and automatic transmission fluid comes out of the automatic transmission fluid level tube, allow the automatic transmission fluid to come out of the automatic transmission fluid level tube until the overflow stops at a temperature of no more than 40°C (104°F).
10. Install the transmission fluid level plug. Install a new level plug and sealing washer. Tighten to 15 Nm.
11. Install the automatic transmission fluid charging pipe cap.
12. Lower the vehicle.
13. Disconnect the Jaguar Approved Diagnostic System.
