Note:
This information applies to the vehicles mentioned above that are operated in counties which have substantially all of their area above 4000 ft. (Ref. Federal Register). For your convenience we have listed the Designated High Altitude Counties.








A harsh 3-2 shift condition at high altitude may be corrected by installing the appropriate Service Package containing:
^ 1 3-2 Control Valve Spring (341) (refer to Figure 4)
^ 2 Spacer Plate Gaskets
^ 3 Instruction Sheets


Before installing Service Replacement Transaxle Assembly (SRTA) in areas designated as "high altitude," install the new 3-2 control valve spring.
