What are the symptoms of a torque converter failure?
1 Answers
The symptoms of a damaged torque converter include excessively high torque converter oil temperature and abnormal noises during operation. Excessively high torque converter oil temperature: High oil temperature is typically manifested as normal engine operation but increased fuel consumption, very high transmission and transmission oil temperature, and the transmission oil being prone to deterioration. In severe cases, white smoke may emerge from the oil filler port. The possible causes could be insufficient oil in the torque converter, clogged cooling oil pipes, or worn torque converter thrust bearings, leading to excessive blade clearance between the impeller, turbine, and stator. This causes part of the fluid energy to be lost in the form of heat, raising the oil temperature. Abnormal noises during torque converter operation: Abnormal noises during torque converter operation are mainly caused by bearing damage, loose connections of the working wheel, or loose connections with the engine. In such cases, first check for any looseness in the connecting parts, then inspect the bearings. If there is excessive play, they should be adjusted or replaced. Additionally, check the quantity and quality of the hydraulic oil, and add or replace the oil if necessary.
