Which gear should be used when climbing a slope with a car?

[McColeman]

When climbing a slope, use 2nd or 3rd gear for manual transmission cars. For automatic transmission cars, you can use the S (Sport) or L (Low) gear, or simply the D (Drive) gear. Climbing requires greater torque, so the transmission should remain in a lower gear to increase the wheel torque. Whether going uphill or downhill, both manual and automatic transmission cars should engage a low gear. Especially during slow uphill climbs, a low gear provides the necessary power. Using too high a gear may cause the car to stall during climbing. Although automatic transmission cars rarely or never stall when going uphill, it is still better to use a low gear for climbing because it offers higher torque and stronger power.
