THE "PERFORMANCE SHIFT" INDICATOR LIGHT LOCATION WAS CHANGED IN SEPTEMBER OF 1998 (AFTER VIN 213057). THE LIGHT WAS ORIGINALLY IN THE INSTRUMENT PANEL (IP) CLUSTER AND WAS MOVED TO THE TRIP COMPUTER. THIS INDICATOR LIGHT IS ONLY USED ON VEHICLES WITH THE 3.8L, L67 SUPERCHARGED ENGINE.

NEW CLUSTER WILL NOT HAVE A "PERFORMANCE SHIFT" BULB. ADD A BULB, P/N 16151234.

2. TRIP COMPUTER REPLACEMENT:

REMOVE THE ORIGINAL CLUSTER; REMOVE THE BULB AND REPLACE THE CLUSTER. THE INDICATOR LIGHT WILL NOW OPERATE IN THE TRIP COMPUTER.

SECOND DESIGN VEHICLE (1999 MODELS AFTER THE ABOVE VIN BREAKPOINT) -

1. NO ACTION NECESSARY.

THIS CHANGE WILL NOT OCCUR UNTIL THE EXISTING SUPPLIES OF THE ORIGINAL PART NUMBERS HAVE BEEN USED UP. UNTIL THAT TIME, DEALERS WILL RECEIVE THE ORIGINAL PARTS AND NO ACTION IS NECESSARY. DEALERS SHOULD INSURE THAT WHEN EITHER PART IS REPLACED, THE VEHICLE HAS ONE AND ONLY ONE INDICATOR LIGHT.
