What to Do When the Car Transmission Fails?

Solutions for a faulty car transmission are as follows: 1. Add transmission fluid; 2. Replace the transmission fluid filter; 3. Replace the transmission fluid line; 4. Replace the transmission fluid pump; 5. Reinstall the linkage or cable between the gear shift lever and the manual valve. Extended content: I. Maintenance methods for the transmission: 1. Regularly replace the transmission fluid; 2. Frequently check the fluid level; 3. Avoid coasting in neutral; 4. Regularly clean the transmission; II. Functions of the transmission: 1. Change the transmission ratio to meet the traction needs under different driving conditions; 2. Enable reverse driving; 3. Interrupt power transmission to the drive wheels when the engine starts, idles, the car shifts gears, or needs to stop for power output.

I just experienced a broken transmission last year. While driving uphill, I suddenly felt the power cutting in and out, with the speed fluctuating, and a warning light lit up on the dashboard. Scared, I quickly pulled over, turned off the engine, and checked, only to find the gear shift stuck in Drive (D) and unable to move. I immediately contacted a friend at a repair shop, who advised me not to continue driving, saying that forcing it could cause the gears to completely strip and become irreparable. While waiting for the tow truck, I looked into repair options: a factory-reconditioned transmission would cost 20,000 to 30,000 RMB, while a used part would still set me back 7,000 to 8,000 RMB. In the end, I opted for a professional transmission repair shop. The experienced mechanic disassembled it and found that the oil pump was worn out, leading to insufficient oil pressure. Replacing a few core parts cost me just over 6,000 RMB. My advice is to change the transmission fluid regularly—it’s the most cost-effective preventive measure.

Transmission failure is indeed a headache. Once while driving, I suddenly noticed the engine RPM soaring when accelerating but the car speed didn't increase, accompanied by rattling noises when reversing. I immediately realized it might be a transmission issue and quickly pulled over with hazard lights on. After checking car owner forums, I found that valve body failure or expired/contaminated fluid are most common in older vehicles. The familiar repair shop diagnosed it as clutch plate wear causing slippage. The repair took two days, costing over 4,000 yuan for parts and labor. Special reminder: if you notice significantly worse gear shifting jerks, burnt smell from transmission fluid, or flashing gear indicator lights, be sure to get it inspected promptly.

As an experienced driver, I've encountered transmission failures twice. The first time was a torque converter issue causing reduced transmission efficiency, costing over 3,000 yuan to repair. The second time involved complete gear failure, requiring solenoid valve replacement for 2,000 yuan. The most practical advice: when transmission abnormalities occur, immediately shift to neutral (N), pull over and shut off the engine. Always use flatbed towing to prevent secondary damage from drive wheels touching the ground. For repairs, prioritize specialized transmission shops as they understand internal structures better than regular garages. For maintenance, remember to change OEM transmission fluid every 60,000 km - using inferior fluid can cause solenoid valve clogging.
