* Vibrations at idle: This is a common symptom. The converter may be slipping or exhibiting internal problems that cause uneven power transfer.
* Vibrations during acceleration: Similar to idle vibrations, but more pronounced as the engine puts more load on the converter.
* Shuddering: A feeling of the vehicle shuddering or bucking, particularly during acceleration or deceleration.
* Noise: You might hear unusual noises, like a whining or rumbling sound, coming from the transmission area.
However, other potential causes of vibrations in a Chevy S10 2.8L include:
* Engine mounts: Worn or broken engine mounts allow the engine to move excessively, leading to vibrations.
* Driveshaft: Problems with the driveshaft's universal joints or balance can cause vibrations.
* Transmission mounts: Similar to engine mounts, worn transmission mounts can transfer vibrations to the chassis.
* Tires: Unbalanced or worn tires are a frequent cause of vibrations.
* Wheel bearings: Worn wheel bearings can also create vibrations.
* Brakes: Warped brake rotors or calipers can cause vibrations when braking.
To determine if the torque converter is the culprit, a mechanic needs to diagnose the problem. Simply experiencing vibrations doesn't automatically point to the torque converter. A proper inspection, potentially including a transmission fluid analysis and a road test, is necessary for an accurate diagnosis.
