What are the symptoms of transmission failure in a Focus?

The transmission failure symptoms in a Focus include abnormal noises when in neutral, unusual noises from low-speed gears, reduction or elimination of noise in high-speed gears, abnormal sounds from various gears in the transmission, and noise from the transmission assembly. The relevant troubleshooting methods are as follows: If there is a metallic dry friction sound while driving and the transmission housing becomes hot, this is noise caused by deteriorated lubricant. It is necessary to add oil or check the oil quality, and replace it if necessary. If there is noise in neutral, and the sound disappears when the clutch pedal is depressed, this is usually due to loose front or rear axle bearings or meshing gear sounds. Any gear can produce noise, but if the noise comes from the rear bearing of the second shaft, it indicates severe looseness or damage to the bearing, which requires repair or replacement. When the vehicle is driving at low speed, it may produce irregular noises, and as the speed increases, more chaotic gear impact sounds and filtering noises may occur. If the noise is relatively loud but the cutting force is even, the vehicle can continue to be used for break-in. If the noise is severe or uneven, it should be disassembled for inspection and break-in, and adjusted or replaced if necessary.
As a long-time owner of a classic Focus, the most obvious sign of transmission issues is the car shaking like a massage chair when moving at low speeds, especially with loud clunking noises during gear shifts below 20 mph. Sometimes, it takes two or three seconds for the car to react after shifting into reverse, which is incredibly frustrating. Problems are most likely to occur in summer traffic jams under high temperatures, with sudden power loss feeling like being yanked from behind, accompanied by a small wrench warning light on the dashboard. When you hear metal grinding noises coming from the chassis, it's time to prepare for repair costs. Key areas to inspect are the clutch module and shift fork—eight out of ten fellow owners in our group have had issues with these components.
Over the years of repairing Focus transmissions, I've summarized the common failure patterns: When starting a cold engine, the shift from 1st to 2nd gear feels like being kicked, with an extremely harsh jerk. During uphill climbs, the RPM surges to 4000 but the speed won't increase, accompanied by a burning smell when gear slippage occurs. The most troublesome issue is when shifting to D mode—the dashboard shows D position but the car behaves like it's in neutral, requiring an engine restart to function normally. Ford's dual-clutch design flaw leads to oil leaks from seals as a chronic problem; when oil seeps into the control module, it triggers protective mode with gear lock.
From a used car dealer's perspective, the most dreaded Ford Focus transmission failures manifest in three ways: First, the gearshift cable position sensor fails, causing the P gear to lock and the key to be stuck. Second, the transmission oil pan leaks, dripping oil and leaving a pool of red fluid on the ground. Third, the car body vibrates at high frequency when driving at a steady speed of 50 km/h, making the steering wheel tingle. These cars usually result in loss-making repairs when acquired, especially the 2012-2015 models with 6-speed dual-clutch transmissions.
