SRTA PROGRAM INTRODUCTION PROCESSING PROCEDURE OUTLINED

TRANSMISSION APPLICATIONS: 200-4R

SUBJECT: SERVICE REPLACEMENT TRANSMISSION ASSEMBLY (SRTA) PROGRAM INTRODUCTION

TRANSMISSION MODELS:

VEHICLE APPLICATIONS: ALL 1982-90 CARS W/200-4R

BULLETIN COVERS:

The THM 200-4R Service Replacement Transmission Assembly (SRTA) Program beginning March 15, 1990. SRTA models can be ordered for all 1982-1990 models from your local General Motors Service Parts Operation (CANSPO)

SRTA ADVANTAGES:

- A SRTA is the product of a highly successful, customer satisfaction driven program that parallels the existing HYDRA-MATIC 3T40, HYDRA-MATIC 4T60 and HYDRA-MATIC 4L60 programs. It provides the technician with a service alternative when addressing diagnostic and overhaul concerns.

- All SRTA units are designed and remanufactured to current engineering specifications and are often less costly than a major overhaul.

- IN THE INTEREST OF CUSTOMER SATISFACTION, SRTA MODELS SHOULD ONLY BE CONSIDERED WHEN THE PROJECTED COST OF REPAIR EXCEEDS THE COST OF A SRTA REPLACEMENT.

GENERAL GUIDELINES:

o Replacement or Overhaul:

Parts needed to perform unit replacement or internal overhaul on a THM 200-4R transmission are available through your local Parts Distribution Centre (PDC).

- Transmission conditions considered for SRTA usage: o All repairs in which the projected cost to repair exceeds the cost of SRTA replacement. o Indications that major internal repair is required.

- Dealer THM 200-4R transmission repairs include: o All on-vehicle serviceable items. o All internal repairs which are projected to cost less than a SRTA replacement.

COOLER FLUSHING:

IMPORTANT: Cooler flushing MUST be performed whenever a transmission/ transaxle is removed for service. It is essential to flush the cooler after SRTA installation, major overhaul, in any case of pump or torque converter replacement, or when fluid contamination is suspected. Use Kent-Moore tool J-35944 to flush the cooler.

SRTA PROCESSING PROCEDURE:

Each SRTA unit will be shipped in a container which must be used for core return of the original THM 200-4R assembly. A SRTA Information Packet is included with each SRTA unit. The contents of this envelope are to be removed and used as described with each illustration on the following pages.

SRTA PROCESSING PROCEDURES - FAILURE ANALYSIS INFORMATION:

This Product Feedback Form is to be completed by the service manager and/or technician. Fill out this form as completely as possible to provide information which can be used for analysis. This valuable input can result in future product refinement through corrective action. Insert the white copy of the completed form and a copy of the repair order into the SRTA Information Packet envelope, reseal the envelope and wire tag it to the bell housing of the unit being returned for core exchange.

PARTS INFORMATION:

- Part numbers are accurate at the time of printing and subject to change.

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.
