What are the precursors of transmission failure in the Excelle GT?
3 Answers
Excelle GT transmission failure precursors are as follows: 1. Transmission oil leakage: You can clearly feel that the car is struggling to start, and although the engine speed increases when you step on the accelerator during driving, there is no obvious sense of acceleration. The culprit may be oil leakage. Oil leakage will lead to insufficient internal lubrication of the transmission, causing the transmission to fail to work properly. This situation is relatively simple, just replace the transmission oil. 2. Transmission jerking: The symptoms are obvious jerking and shaking during gear shifting while driving. The reason may be that the transmission oil temperature is too high, and there is stubborn dirt and impurities inside, causing blockage in the valve body stroke, leading to transmission jerking. Please go to a 4S shop or repair shop for inspection and repair. 3. Engine stalling after shifting: When shifting from P gear to D gear, the engine will stall immediately. The source may be damage to the solenoid valve or lock control valve, or a fault in the input shaft speed sensor. Stop the car immediately and contact a 4S shop or regular repair shop.
I used to drive an Excelle GT, and there were always signs before the transmission had issues. The most common one was a noticeable jerk when shifting gears, especially at low speeds, as if the car got stuck and then suddenly lurched forward. There would also be strange noises, like a humming or scraping sound from under the car when parked, which became more obvious at high speeds. Another sign was the transmission warning light coming on—it might flicker a few times and then go off at first, but don’t assume it’s fine; check immediately for leaks or a burnt smell in the fluid. Other symptoms like sluggish acceleration, delayed response, or feeling like the power just can’t keep up when overtaking are also red flags. From my own experience, I know that ignoring these minor issues for too long leads to higher repair costs. The worst was when I delayed for over half a year, and the transmission completely failed, forcing me to spend a fortune on a full replacement. My advice: if something feels off, don’t wait—take it to a reputable shop right away for diagnosis. Don’t try to save money by going to a small repair shop.
As someone who frequently repairs Buick vehicles, early detection of transmission issues in the Excelle GT is crucial. Warning signs include rough or hesitant shifting, abnormal noises such as whining or clunking, fluid leaks leaving oil stains on the ground, and sluggish acceleration with unresponsive throttle. If the gear indicator light on the dashboard flashes or displays error codes, it may indicate a fault in the electronic control module. I would advise owners to first check if the transmission fluid level is low or deteriorated, smell for a burnt odor, and then test the shifting response. Ignoring these early signals can lead to severe damage to gears or clutch plates, driving repair costs up to thousands of dollars. It's best to have technicians check fluid pressure and the electronic control system during regular maintenance to prevent issues and save both hassle and money.
