I have a 94 4 Runner that has a light in the dash that shows A/T Oil, what does that mean ? Also the battery guage keeps shooting up like it is over charging. Can anyone clue me in ? Thanks

 

The A/T Oil light is a temp. warning for the transmission, excessive heat being the most common cause of auto. trans. failure. Not sure on the voltmeter issue, but I'd check your battery terminals to make sure they're tight just for good measure. Normal voltage should be slightly over 14 volts.
