SITUATION:
TRANSMISSION WATER INGRESS THROUGH BREATHER
Condensation from Air Conditioning and water from a "deep wading" event can flow over the transmission and collect on the transmission breather tube
on Range Rover and Discovery Series II vehicles. It can then migrate up the transmission tube. Over time these small water droplets can
cause an accumulation of water in the transmission causing problems associated with water contamination harsh gear changes, poor gear selection, gear
slip or loss of drive and intermittent failure of the park lock function.
RESOLUTION:
NOTE:
This procedure is complicated. Reading and understanding all of the Option steps is important before undertaking any repairs.
REPOSITION BREATHER TUBE AND INSPECT FLUID
Re-route the breather tube to the top of the transmission to eliminate the breather tube as a source of transmission contamination. Test the park lock
feature of the transmission and then determine if the AT fluid is contaminated by a fluid inspection. Carefully follow the corrective steps to ensure proper
operation of the transmission park lock function and removal of any water contamination.
