What are the precursors of transmission failure in the Buick Excelle GT?
1 Answers
The Buick Excelle GT may exhibit the following symptoms before transmission failure: difficulty starting, especially in low gear, where the engine RPM increases when the accelerator is pressed but the vehicle hardly moves, as if it's not properly engaged in gear. This could indicate a transmission oil leak. Below are related details: 1. Engine stalling when shifting gears: When starting the vehicle, shifting from P or N gear to other gears causes the engine to stall. Alternatively, the engine may also stall when braking while driving, assuming the vehicle does not have auto start-stop functionality. This situation might also be due to an oil leak. 2. Transmission gear lock: During normal driving, the engine RPM rises significantly when accelerating, but the speed increases very slowly. When braking, the speed drops to a certain level and stops decreasing. Switching to manual mode locks the transmission in a specific gear, preventing both upshifts and downshifts, indicating a fault in that particular gear.
