What Causes the Engine RPM to Increase but Speed Doesn't When Pressing the Accelerator in Winter?

[JuniperAnn]

The reasons why the engine RPM increases but the speed doesn't when pressing the accelerator in winter are: 1. The transmission hydraulic oil level is too low or too high; 2. The clutch or brake friction plates and brake bands are excessively worn or burnt; 3. The oil pump is severely worn or there is a main oil circuit leak; 4. The clutch or brake piston seal ring is damaged; 5. The shock absorber piston seal ring is damaged. The solutions for this issue in winter are: 1. Add or reduce transmission fluid; 2. Add lubricant to the automatic transmission or replace damaged components; 3. Conduct a thorough inspection of the transmission oil circuit and repair it promptly; 4. Replace the clutch or brake piston seal ring of the transmission; 5. Replace the shock absorber piston seal ring.

When driving in winter, I press the accelerator and the engine revs shoot up, but the car still moves sluggishly, which is quite frustrating. It might be because the weather is too cold, and the transmission oil becomes as thick as paste, greatly reducing transmission efficiency; or there could be ice and snow on the road, causing the tires to spin wildly without moving, wasting all the power on idling. My own car had this issue, and later I found that clutch wear worsened the slipping. I suggest everyone warm up their cars for five minutes before heading out in cold weather to let the engine warm up a bit; regularly check tire pressure and transmission fluid levels to ensure there are no blockages from impurities; and avoid slamming the accelerator while driving, opting instead for smooth acceleration to reduce the risk of slipping. This way, you can both protect your vehicle and ensure safe driving.

I've been driving for many years and often encounter situations in winter where the engine revs up but the vehicle speed doesn't increase. Common causes include thick transmission oil in low temperatures affecting clutch efficiency, or worn clutch discs in manual transmission vehicles leading to slippage; another reason could be icy roads causing loss of tire traction. After a cold start, I usually let the engine idle for a few minutes to allow components to warm up; I also pay attention to regular maintenance and oil changes, checking fluid quality monthly. If the problem persists, it might indicate an issue with the drive shaft, requiring prompt inspection at a repair shop to prevent more significant failures. In summary, preventive measures and cautious driving can help avoid most troubles.

When driving in winter, I notice the engine RPM increases but the vehicle speed remains unchanged, which raises safety concerns. This is mostly due to tires slipping and losing traction on icy or snowy roads, or thickened transmission fluid in cold temperatures hindering power delivery. I immediately reduce speed, drive cautiously, and activate the snow mode to enhance tire tread grip. After returning home, I check the antifreeze condition of the oil lines to ensure smooth fluid flow. Regular vehicle maintenance is recommended to prevent aging issues. In such situations, avoid sudden acceleration and maintain a steady speed for peace of mind. After all, driving safety comes first, and preventing minor issues isn't difficult.

I've encountered the issue of high engine RPM but slow vehicle speed in winter several times. The main reasons include: transmission oil being too thick in cold weather making power transfer difficult; clutch slippage causing power loss; tires lacking traction on ice. After parking, I prioritize checking oil levels and tire pressure, and warm up the car for a minute or two before driving; if the problem persists, it might indicate clutch or automatic transmission failure requiring part replacement. Maintaining good vehicle condition is the most cost-effective and worry-free approach – don't neglect routine small checks.
