Is Starting at 2500 RPM Harmful to an Automatic Transmission Car?

[AdalineRose]

"Starting an automatic transmission car at 2500 RPM can cause damage because the vehicle typically shifts from lower to higher gears during acceleration. 2500 RPM is considered a relatively high engine speed, and if the gear is low while the throttle is high, it can increase engine wear. High engine speed during startup is normal. Generally, the engine speed can reach 1200-1500 RPM at startup. In colder seasons, the engine speed may be even higher because too low an RPM can cause the car to stall, and a slightly higher speed helps warm up the engine faster. However, during a cold start, the RPM should not be excessively high. Since lubricant cannot fully reach the upper parts of the engine, keeping the RPM below 2000 is more suitable to minimize wear. Once the engine stabilizes, the RPM will drop to around 800. If the RPM is too low, fuel combustion in the cylinders may be incomplete, leading to insufficient power and increased carbon buildup in the engine. Over time, this can cause significant damage to the engine. Conversely, if the RPM is too high, the most noticeable effects are increased fuel consumption and greater engine wear."
