Simple Job Check Your Transmission Fluid
OK to you and me the transmission is the gearbox, either manual or automatic. just like the engine it needs lubrication fluid to keep it right and trouble free. This is an American video but shows you how easy it to check your transmission fluid, expecially on front wheeled drive vehciles, where the gearbox is under the bonnet with the engine.
You can do this job in minutes and to be honest most gearboxes can outlive the car, so dont expect to find much wrong.
