FLUID LEAKS FROM FILL TUBE NEW OIL DEFLECT ON CONTROL VLV

VEHICLES AFFECTED: 1982-86 THM 700-R4 Transmissions

The following Bulletin applies only to the transmission models listed below:

YAM, YCM, YDM, YFM, YMM, YPM, YSM, YWM, YXM, YZM

Beginning November 19, 1985, or Julian date 323 (refer to figure 1), certain 1986 THM 700-R4 transmission models (refer to model usage above) were built with a new oil deflector on the control valve assembly.

The new oil deflector, secured to the control valve assembly by two existing bolts (refer to figure 2), will prevent transmission fluid from spilling out of the oil fill tube during rapid reverse to drive shift maneuvers.

The new oil deflector can be used on any 1982 through 1986 THM 700-R4 transmission, exhibiting this condition, by ordering Service Part Number 8654702.

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.
