.
TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CONDITION:)
• Malfunction of the engine
• Insufficient transmission fluid level
• Poor adjustment of transaxle control cable
• Malfunction of the torque converter
• Malfunction of the valve body assembly
• A/T failure: Hydraulic system (valve body assem-
bly, oil pump), driving force transmission system
(parking mechanism, clutch/brake, gears)
