Recall - A/T Breather Tube Modification
No: D352Ref: D321-D324
Issue: 1
Date: 01/12/99
RECALL
Transmission Breather Tube Modification
AFFECTED VEHICLE RANGE:
RANGE ROVER (LP) SA302295 to WA402293
WA402294 to XA410503
SITUATION:
Water can become captive in the end of the transmission breather tube installed as part of Recall D321-D324 or in late production GEMS vehicles. If the water freezes, transmission fluid may be forced from the dipstick assembly with the potential for an engine fire.
RESOLUTION:
ALTER THE END OF THE INSTALLED TRANSMISSION BREATHER TUBE
On all vehicles modified or equipped with a transmission breather tube which terminates at either the left or right fender well location, the routing of the hose must be adjusted and the end trimmed and positioned as per the procedures outlined below.

REPAIR PROCEDURE:
AUTOMATIC TRANSMISSION BREATHER PIPE MODIFICATION
1. Open vehicle hood.
CAUTION:
Routing of the breather pipe for campaign D321-D324 is to the LH inner fender. (Figure 1) Routing of the breather in production AFTER VIN WA402293 is to an alternate location on the RH inner fender. (Figure 2) BOTH locations require the same modification to the breather.
2. Locate the transmission breather pipe:
^ On Recall vehicles routed along the bulkhead to the left side
^ On production vehicles routed along the bulkhead to the right side
CAUTION:
Do not remove hoses from the purge canister.
3. If the vehicle has a Recall breather pipe, remove the bolt securing the purge canister to provide access to the inner fender area.
4. Disconnect the breather pipe from the two retaining clips along the engine bulkhead.
5. If the vehicle has a Recall breather pipe, remove the snap fit end of the breather pipe from the location at the LH inner fender. (Figure 1)
6. If the vehicle is equipped with a production breather pipe, remove the snap fit end of the breather pipe from the location at the RH inner fender. (Figure 2)
7. Measure 180 mm (7.5 inches) from the tip of the breather pipe snap end fitting.
CAUTION:
Ensure that the angle of the cut is made so that the opening is oriented toward the inner fender wall.
8. Refer to Figure 3 and Figure 4. Cut the breather pipe at a 45-degree angle as shown.
9. Slit the top side of the pipe back about 15 to 20 mm (5/8 to 3/4 inch) as illustrated in Figures 3 and 4.
CAUTION:
Location of the breather pipe into the securing clips is vital to ensure correct retention of the pipe. The proper location of the breather pipe opening must be maintained during vehicle operation by securely anchoring the pipe in both clips.
CAUTION:
On both installations it is important that the end of the breather tube have 25 mm (1 inch) clearance from the electrical harness to ensure that there is no harness damage or any potential for contact with the breather tube.
10. If the breather pipe is in the production (right side) location, move the evaps hose clip outboard of the evaps hose shielding to better support the end of the breather pipe. (Figure 4)
11. Secure the breather pipe to the two pipe clips so that the modified end of the breather tube is approximately 25 mm (1 inch) from the under-hood harness located in the corner of the engine bay.
12. Install the purge canister if loosened.
CAUTION:
Kinks, deformation or pinching of the breather tube can result in pressure buildup in the transmission. Fluid loss from the dipstick may result.
13. Verify that there are no kinks or deformations in the breather pipe created during the installation or modification process.
14. When the repair has been accomplished, prepare the Recall label. (LRN0002LABEL)
15. Clean the radiator support, position the label on the radiator support and roll the label to ensure that the adhesive makes continuous contact with the cross member surface.
