Engine flare, pump whine or transaxle slip, during vehicle turns, may be caused by low fluid level or the fluid filter.
DATE OF PRODUCTION CHANGE: (Figure 1) -------------------------
Starting April 6, 1987 (Julian date 096), all THM 440-T4 transaxles were built using a filter with a new inlet baffle design.
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 in Service Parts Information.
Service Package Number 8646902 (Filter and Seal Package) contains the following items:
- Oil Pan Gasket - Fluid Filter Assembly - Filter Intake Pipe to Case Seal
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.
