#### Model and Year 1984-1987 CELEBRITY WITH THM 440-T4 TRANSAXLE

Engine flare, pump whine or transaxle slip during vehicle turns may be caused by low fluid level or the oil filter.

Starting April 6, 1987, (Julian date 096, Figure 1), all THM 440-T4 transaxles were built using a filter with a new inlet and baffle design.

To repair this condition, check for proper fluid level and correct, as necessary. If the flare still occurs, remove the bottom pan, and replace the filter and seal with a new filter and seal package listed below.

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.
