Summary

A PLASTIC FILLER PIECE LOCATED IN THE AUTOMATIC TRANSMISSION WAS INSTALLED WITHOUT SUFFICIENT SUPPORT. THIS FILLER PIECE CAN MOVE BECAUSE OF THE HYDRAULIC PRESSURE IN THE SYSTEM, AND NOT ALLOW THE AUTOMATIC TRANSMISSION TO KICK DOWN TO A LOWER GEAR.

Consequence

IF THE ACCELERATOR PEDAL IS PUSHED INTO THE KICK-DOWNPOSITION, THE EXPECTED ACCELERATION OF THE VEHICLE MAY NOT OCCUR DUE TOINTERFERENCE OF THE FILLER PIECE. THIS COULD RESULT IN AN ACCIDENT DURING AVEHICLE PASSING MANUEVER.

Remedy

DEALERS WILL INSTALL A NEW FILLER PIECE WHICH HAS A SECURING BRACE TO PREVENT MOVEMENT.
