Transmission problem
1989 Chevy Corsica 6 cyl Front Wheel Drive Automatic 215765 miles
----------------------------------------------------------------
My '89 Corsica started slipping going into reverse and has now decided that reverse is no longer an option. Fluid level is fine but I only recently acquired this car and have no real idea as to how well it's been maintained. Is this a simple change the filter and fluid problem or do I have to throw money at a mechanic?
