What Causes the Gear Position of an Automatic Car to Overheat?
2 Answers
Automatic car gear position overheating can be caused by the following reasons: 1. Generally, it is caused by poor heat dissipation, and the reason for poor heat dissipation is a problem with the radiator; 2. Damage to the solenoid valve coil inside the gear position, with the solution being to replace the coil; 3. If there is no malfunction, then it is a normal phenomenon because the engine is located below, and heat rises. When the temperature is too high, it is necessary to go to a professional repair shop for inspection. Below is more information about automatic gear positions: 1. The P gear is used for long-term parking and is generally used in conjunction with the N gear. When the P gear is engaged, it can prevent the car from rolling. 2. The R gear is the reverse gear. When reversing, it is generally used after the car has come to a complete stop. 3. The N gear is the neutral gear, which can be used for short-term parking or in conjunction with the P gear for long-term parking.
I noticed the automatic gear shift lever feels hot while driving, which is quite common but still requires attention. During long highway drives or stop-and-go traffic in the city, the transmission constantly shifts gears and generates heat. Since the gear lever is connected to the transmission, it conducts this heat. In summer, with the AC on, the engine works harder and temperatures rise higher, so occasional mild warmth is normal. However, if it's scalding hot accompanied by a burning smell or rough shifting, it's time to check the transmission fluid—low levels or degraded fluid impair cooling, and if the oil appears black, it should be replaced. Additionally, frequent hard acceleration and braking can cause clutch plate friction heat, which transfers up to the gear lever. My tip: after parking, touch the transmission housing to compare temperatures and identify abnormal overheating. Never skip transmission fluid changes during routine maintenance.
