Some 1983 and 1984 Devilles and Broughams equipped with THM 200-4R model transmissions or Eldorados and Sevilles equipped with THM 325-4L model transmissions may experience a harsh 1-2 upshift condition. This harsh 1-2 upshift condition may be caused by the second clutch check ball (#8) peening the second clutch apply oil hole on the spacer plate. For location of the second clutch apply oil hole on the spacer plate, refer to Figure 1 for the 200-4R and Figure 2 for the 325-4L. To correct this condition, replace the valve body to spacer plate gasket, spacer plate to case gasket and spacer plate. Refer to the parts list for correct part numbers for all applications.
