2ND GEAR START OUT NEW GOVERNOR ASSEMBLY

VEHICLES AFFECTED: 1985 THM 440-T4 CP, CW or HT Models Only

Some 1985 THM 440-T4 model CP, CW or HT transaxles (refer to Figure 1) may exhibit a condition of second gear start out with the selector in 'DRIVE' after coastdown from second, third or fourth gear operation. The condition may occur several times (especially when the transaxle is cold) and may be caused by the 1-2 shift valve remaining in the upshifted position due to residual pressure in the governor circuit.

The following chart lists, by model, the Julian date a new governor assembly went into production and the service replacement part number.

Model Julian Date Service Part Number ----- ------------ ------------------- CP 100 8644961 CW 81 8644963 HT 82 8644963

To repair the second gear start out on any 1985 THM 440-T4 model CP, CW or HT transaxle built before the listed Julian date, install the appropriate new design governor assembly. Refer to the Service Information manual for proper service procedures.

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.
