OK its a 2005 Chevy Aveo LT 1.6L Automatic the car has roughly 98000 miles on it the car was warmed up thouroghly temp outside was 41 degrees ferenhiet and i was doing about 60 mph and for about 5 seconds the Check Engine and Hold Lights flashed and the transmission seemed to stay in a low gear the car seemed to be running just fine before this happened any one out there has any answers

it happened to me once and i just stopped and shifted around a couple times and it never happend again ( no idea the cause) and rarely on cold mornings before it has warmed up

I would not worry about it, but, have you had any major issues with it at almost 100k miles?

OK the Aveo passed emissions the other day and still had no reoccurance of the lights flashing together and as for any major issues being so close to 100K only the back axle bushing are shot and I hear a clunking noise when hitting bumps and it throws the wheel alignment off makeing the front tires go bad fast oh yeah and it feels like the MPG might of gone down
