What Causes a Car Not to Move When Pressing the Accelerator?

[AriannaDella]

An automatic transmission car not moving when pressing the accelerator may be due to several reasons: the clutch not engaging properly; the handbrake not being released; the gear being stuck and not fully engaged; or the clutch friction plates being worn out. Below is relevant information: Automatic Transmission Gears: Most automatic transmissions have 6 to 7 gear positions, arranged sequentially from front to back. These are: P (Park), R (Reverse), N (Neutral), D (Drive), and some Drive modes include D, 3, 2, and 1. Some models only have three Drive positions (D, 2, and 1). If equipped with a four-speed transmission, there may also be an Overdrive (O/D) switch to engage the overdrive gear. Correct Driving Method: The correct way to drive an automatic transmission car is to start the engine with the gear lever in P (Park) and always press the brake pedal before shifting from P to any other gear. When starting, shift the gear lever to a lower gear (such as 2 or 1, or sometimes 3), and once the speed increases sufficiently, shift to D (Drive) for normal driving. When cruising at high speeds on a highway, using the O/D (Overdrive) gear can save fuel.
