How to Restore Transmission Failure?
2 Answers
Solutions can be determined based on different failures: 1. Automatic transmission oil leakage: Cause of failure: Different models have different leakage locations. The main reason for leakage is poor sealing effect of sealing components, and sometimes it can also be caused by pitting, rust, etc. on the parts. If the leakage is not addressed in time, the transmission will operate with insufficient oil for a long time, leading to further severe internal damage. Repair solution: Overhaul the transmission and replace the sealing components. 2. Vehicle does not move after releasing the brake when in gear: The vehicle can start by accelerating but with noticeable jerking. Cause of failure: Mainly due to pressure leakage in the components responsible for the first gear oil circuit inside the transmission, such as the E1 clutch retaining ring, E1 clutch piston, etc. If this failure is not repaired promptly, it will further damage the transmission's oil pressure solenoid valve, causing severe internal damage to the transmission. Repair solution: Overhaul the transmission and replace the related first gear oil circuit components. 3. Vehicle SPT light and failure light alternately flashing: Cause of failure: The oil pressure solenoid valve is damaged, preventing the transmission from establishing normal working oil pressure (no boost). This failure must be addressed immediately; otherwise, it will cause severe internal burning of the transmission in a short time. Repair solution: Replace the oil pressure solenoid valve.
Last time I was driving, my transmission failed and the gears got stuck, unable to shift. I pulled over, turned off the engine, and checked the transmission fluid. I found the fluid level was very low and the color was dark, so I added new fluid to try. After restarting, the situation improved a bit but wasn’t completely fixed. Transmission fluid aging or leakage is a common issue, but the cause could be more, such as sensor failure or mechanical wear. Adding fluid as an emergency fix is feasible but only temporary. I suggest that if owners encounter a similar problem, they should first check the fluid level and quality themselves. If that doesn’t help, go to a repair shop immediately to scan for trouble codes and diagnose the issue. Remember, continuing to drive with a problem can lead to more severe damage, such as burning out the clutch plates, which will significantly increase repair costs. So, safety first—don’t be afraid of the hassle. Maintenance is key to prevention; regular fluid changes and inspections can prevent many failures.
