"SERVICE BULLETIN - SOME VEHICLES MAY STILL EXPERIENCE THE SHUDDER EVEN AFTER THE PGM-FI SOFTWARE HAS BEEN UPDATED BECAUSE THE ATF HAS DETERIORATED. THE PROBLEM IS TYPICALLY DIAGNOSED AS A BAD TORQUE CONVERTER. THERE IS NO DAMAGE TO THE TORQUE
CONVERTER, BUT BECAUSE THE ATF HAS DETERIORATED, THE FLUID NEEDS TO BE CHANGED EVEN THOUGH THE ATF SERVICE DUE
MESSAGE HAS NOT APPEARED. MAKE SURE THE VEHICLE IS UPDATED BY REFERRING TO THE INSPECTION PROCEDURE."
