What are the reasons for the automatic transmission warning light to illuminate?
1 Answers
Automatic transmission warning light may illuminate due to the following reasons: Oil leakage: Oil seeping from the transmission housing or oil pan. One reason is aging seals causing poor sealing; another reason is manufacturing defects leading to sand holes in the housing. Engine stalling when shifting: Engine stalls when shifting into D or R gear. This fault may be caused by a damaged lock-up solenoid valve or a stuck lock-up control valve. Gear lock-up: Incorrect input/output signals from the transmission, or malfunctioning components/circuits. Sometimes it can also be caused by communication issues between the transmission computer and other system computers.
