ADDITIONAL INFORMATION ON NEW DESIGN CONTROL VALVE ASSEMBLY

Model and Year ALL 1982 THRU 1985 THM 700-R4 TRANSMISSIONS

Some recent comments indicate that some confusion still exists on how to identify the new design Control Valve Assembly as referenced in Chevrolet Dealer Service Bulletin 84-107 dated April, 1984.

The Control Valve Assemblies can be identified as follows:

1. The new design Control Valve Assembly used in production starting on January 15, 1984, (Julian date 015) is identified by one of two ways:

a. Casting number 2264 with a letter "X". (See Figure 1)

b. Casting number 4256. (See Figure 2)

2. The past design Control Valve Assembly (or build dates prior to Julian Date 015) is identified by the casting number 2264 without an "X".

NOTICE: ALL CONTROL VALVE ASSEMBLIES ORDERED FROM THE WAREHOUSING AND DISTRIBUTION DIVISION OF GENERAL MOTORS (WDDGM) WILL BE IDENTIFIED AS INDICATED IN ITEM 1 ABOVE.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
