Your vehicle’s transmission is the powertrain that converts your engine’s force into a controlled source of power. It basically transfers the power your engine produces to the wheels. The vehicle’s transmission allows for better control of the speed for the driver, the transmission is the mediator for your engine and wheels.
If your vehicle is responding slowly when you accelerate then that is a good sign your transmission may have issues. Clunking sounds when the car is shifting gears, leaking transmission fluid beneath the car (automatic transmission fluid is bright red in color), grinding or shaking when the car is going through the gears, burning smell produced by the overheating fluid, refusal to go into gear, check engine light, transmission makes noise in neutral, gears slip when driving causing the engine to rev up and the car is hard to get out of gear or won’t go into gear are all signs your transmission may have issues.
