LEXUS (LX) Owners to reprogram the Automatic Transmission ECU
Campaign Summary
Abdul Latif Jameel Co. Ltd would like to inform owners of LEXUS (LX) of Recall/Special Service Campaign on their vehicles to reprogram the Automatic Transmission Computer because the Automatic Transmission contains linear solenoids to control the shifting of gears. If a solenoid failure occurs under certain driving conditions, the Transmission Electronic Control Unit (T-ECU) and the Engine ECU may not communicate the failure, resulting in the transmission over-revving in certain gears. This could result in damage to the transmission and a loss of motive power while driving at higher speeds. If certain damage occurs to the transmission housing, there is also the possibility for transmission fluid to leak from the housing. These conditions can lead to an increased risk of a crash or a fire in the presence of an ignition source.

What is the condition?
