BMW 5 Series Transmission Issues: 1. Electronic component failure in the transmission. Solution: Computer diagnostics and replacement of damaged electronic components. 2. Severe wear of mechanical components in the transmission. Solution: Repair of damaged mechanical components. 3. Incorrect signals from the engine or ABS interfering with transmission operation. Solution: Inspect the engine and ABS, and repair any damaged electrical components. 4. Contaminated transmission fluid clogging the solenoid valves. Solution: Disassemble and clean the transmission valve body, and replace the transmission fluid. 5. Damage to the transmission control unit (TCU). Since solenoid valve signals are processed by the TCU, a faulty TCU can lead to abnormal signal processing, causing the vehicle's monitoring system to report solenoid valve error codes. Many solenoid valves are integrated into the TCU.

What does rpm on the car dashboard mean?

RPM on the car dashboard refers to the engine's revolutions per minute. Generally, the faster the engine speed, the more power it can provide. The engine drives piston movement by burning air and gasoline, thereby rotating the crankshaft to provide power to the vehicle. This force converted to the crankshaft is called torque. The higher the RPM value, the more air and gasoline need to be burned, resulting in greater power. For drivers of manual transmission vehicles, RPM is one of the criteria for determining whether to shift gears. When the RPM is too low, it is necessary to downshift to obtain more power, while excessively high RPM can have adverse effects on the engine. The RPM value that produces maximum power varies depending on the engine. Generally, it is best to avoid the tachometer entering the red zone to prevent damage to the engine.

Should I Use D Gear or S Gear for Highway Driving?

For highway driving, using D gear is sufficient, while S gear can be employed during aggressive driving or overtaking. Automatic transmissions are equipped with an S gear, where 'S' stands for 'Sport,' indicating the sport mode. When switched to S gear, the transmission enters sport mode, and the engine's operation mode will also adjust accordingly. In S gear, the transmission delays shifting, only upshifting when the engine reaches the redline. D gear is the forward drive gear for automatic cars. When in D gear, the car actively upshifts to maintain lower RPM levels. Common automatic transmission gears include P (Park), N (Neutral), D (Drive), R (Reverse), S (Sport), and L (Low).
