Vehicles Already In Service

If a vehicle has defaulted to "limp home" mode, connect the PDU to the vehicle. Read stored diagnostic trouble codes (DTCs) in the Transmission Control Module and erase them. For all affected vehicles already in service, a complete transmission and torque converter assembly should be installed. Since debris from a faulty component could be circulating in the transmission oil, it is essential that the oil cooler and the connecting lines are flushed as described below before reconnecting the lines to the replacement transmission.

1. While the replacement transmission is removed, position a suitable drain container under the fittings of the oil cooler lines that have been disconnected from the transmission.

2. Disassemble and thoroughly clean a Snap-on(R) syringe (Snap-on reference YA 745) or equivalent, before use.

3. Connect a length of 12 mm bore plastic or rubber hose to the nozzle of the syringe. If necessary, Jaguar Part No. EBC 10850 (Hose, Evaporative Loss Flange to Filler Breather Line) may be used.

Caution:
Absolute cleanliness is critical during the next operations.

4. Fill the syringe from a new 1 liter container of transmission oil. Fit the hose of the syringe to the transmission cooler feed line (the upper of the two lines connected to the cooler), after removing the O-ring from the line. Inject the entire amount of oil in the syringe into the cooler feed line, allowing oil to drain into a waste container from the cooler return line

5. Disconnect the syringe from the hose. Kink the hose to prevent oil flowing from it. Fill the syringe with the remainder of the 1 liter of oil. Reconnect it to the hose and inject the remaining oil into the cooler feed line, allowing oil to drain from the cooler return line. This will flush the oil cooler and lines.

6. Clear away the syringe. Clean up any oil spillage.

7. Install new O-rings on the cooler lines. Reconnect the lines and tighten the union nuts.

Union nut torque: 22 Nm (16 lb. ft.)

Caution:
Handling of torque converter - Use care when easing the transmission assembly away from the engine, and at all other times when the torque converter is not secured and could slide out of the transmission. The torque converter is heavy, especially when still filled with oil.
