Figure 2 - Lo And Reverse Clutch Waved Plate
SERVICE INFORMATION: (Figure 2)
Low and Reverse Clutch failure can be caused by case casting flash interfering with clutch plate travel. A new wave plate is now available which will
alleviate this condition. This new plate can be used to service any Hydra-matic 4L60 transmission produced after February 9, 1987 (Julian Date 040).
When installing the new wave plate, check for any case flash that may be present in the low and reverse grooves, and use a metal file to remove. See
Figure 2 for case location information.
