Internal automatic transmission/transaxle fluid (ATF) restrictions at the inlet side of the oil cooler may be caused by the accumulation of metal particles and debris, from a previous automatic transmission/transaxle (A/T) failure, on the mesh-type baffle of the oil cooler (Figure 1). A/T oil cooler(s) and line flushing procedures are now available. These procedures should be followed before an overhauled or replacement A/T is installed.
Refer to the following Service Procedure to properly power flush the oil cooler(s) and lines.
Before power flushing, be sure to inspect the hoses and clamps. Power flushing MUST begin with back flushing followed by forward flushing, otherwise, the restriction could be further trapped in the internal mesh-type baffle of the cooler and flushing will not be effective or possible.
Be sure to inspect the lines (hoses/pipes) for cuts/scratches, crimps (pinched), cracks/splits or any other damage before reusing the oil hose. If any problem exists or the hose comes off when applying oil pressure, replace it with a new one.
|NOTE:||ALWAYS USE NEW CLAMPS WHEN REPLACING THE HOSES.|
|CAUTION:||IF THE COOLER CANNOT BE PROPERLY FLUSHED USING RECOMMENDED EQUIPMENT, SEND THE RADIATOR OUT FOR SUBLET CLEANING OR REPLACE.|
|NOTE:||CONFIRM THAT DEBRIS NO LONGER EXISTS IN THE FLUSHED FLUID, THEN BACK FLUSHING IS COMPLETED.|
|NOTE:||CONFIRM THAT DEBRIS NO LONGER EXISTS IN THE FLUSHED FLUID, THEN FORWARD FLUSHING IS COMPLETED.|
