Learned quite a bit in the two semesters of Auto Mechanics I took in high school. Never got to do anything major like head gaskets or rebuilds, but smaller things that can save some money if I do it myself. I could do more involved jobs like brakes, shocks & struts if I had the right tools, machines, and a lift. Haven't changed auto tranny fluid since high school, but finally got the chance to do it last week on the Fiero I just bought. Most other cars require removal of exhaust, crossmembers, etc. to get the pan off, but the pan on this car is right in front of your face with zero obstructions. I've since moved on to repairing the headlight motors and replacing the leaky radiator. Easy stuff on this car, since the engine's in the back. Not so easy changing the spark plugs, as one side of the V6 is pretty close to the firewall. It does help knowing you have another car to drive if you take on a job that ends up taking days instead of hours. If I had an engine hoist, I could remove the driver's door to replace the hinge bushings, but it's going to a body shop for that. Not wanting to drop my door on the garage floor and make things 10x worse.
