ISSUE
Some vehicles equipped with a 2.3L, 3.0L or 4.0L engine and 5R44E or 5R55E automatic transmission, produced 6/1/2001 through 3/31/02, operating in cold climates, may exhibit a fluid leak at the transmission Servo Cover(s). This, may be caused by the Servo Cover.
ACTION
Verify the condition. If the condition exists, the Servo Cover(s) may need to be replaced with new cover(s) (Figure 1). Check the transmission fluid level and fluid condition. If fluid is just low and the fluid condition is not burnt, refer to the following Service Procedure to replace the Servo Cover(s). If the transmission shows evidence of damage due to no fluid, no engagements or severely burnt fluid, the transmission may need additional repair or replacement. Follow normal repair or replacement procedures when servicing anything other than the Servo Cover(s).
