Land Rover Range Rover Evoque Trans Oil Cooler Line Replacement Cost

There is no specified replacement interval for transmission cooler replacement lines. However, high mileage vehicles may experience failure of these lines as their rubber parts will degrade over time due to age and heat from driving. More likely, the transmission cooler itself may fail, and the lines will be recommended as part of the repair. Transmission coolers can fail due to heat (in regards to radiator integrated ones) or due to collision.

When any transmission symptoms are present, the technician will first conduct a visual inspection of the vehicle, and note any observed issues. If the transmission issue is related to a leak on the transmission cooler or transmission cooler lines, those components will be inspected, and either resealed, or replaced. n the transmission. Once the suspected component(s) have been tested, any failed component must be replaced, and the transmission will be tested once again.

Once the transmission fluid cooler lines are reconnected, the servicing technician will refill the transmission with new fluid prior to reconfirming the repair.
