MECHANICAL, HYDRAULIC & ELECTRICAL COMPONENTS
1) If gear selector is stuck in Park or Neutral position, go
to SHIFT LOCK SYSTEM under TROUBLE SHOOTING. If gear positions are
missing, shift quality is poor or no shifts are possible, ensure all
electrical connections are okay and fluid level is correct.
2) If problems are still present, disconnect electrical
connector at transaxle. Test drive vehicle. Check if transaxle will
operate manually in reverse and 1st gear. Move gear selector to 2nd,
3rd or "D" position. Transaxle should operate in 3rd gear (2nd, 3rd or
"D").
3) If transaxle operates as described, problem may be
electrical. See ELECTRONIC SELF-DIAGNOSTICS. If transaxle does not
operate as described, problem may be mechanical or hydraulic. See
ROAD TEST.
NOTE: If transaxle does not operate in manual 1st gear, check
1st-3rd apply clutch and reverse brake clutch for damage or
