Torque Converter Problems: Symptoms & Costs

 · 3. Contaminated Transmission Fluid. A torque converter is filled with Automatic transmission fluid (ATF). If the fluid contains debris, grime, or a black sludge, it is contaminated, and this is a sign that the transmission is damaged. Also, dirty fluid can impact the components of the torque converter such as the stator's bearings and turbine.

9 Strange Car Noises (and What They Could Mean)

 · Your car makes a droning noise. This droning noise doesn't change pitch or volume while turning, but it's louder as you accelerate. What it could mean: This noise may be coming from your tires—particularly if they're old or of poor quality. It could also be a sign that you have "feathered" tires—a term used to describe tires with treads that are wearing unevenly.

Troubleshooting Gear Noise

 · So a whiney gearbox is a bad gearbox, even if it is perfectly fit for purpose from a functional point of view. It is a fundamental principle of noise control that the best approach to improve noise in a system is to mitigate the source of that noise. With gear whine, that source is TE; reduce the TE and the noise is reduced proportionally.

Symptoms of a Bad or Failing Driveshaft

 · A driveshaft is a cylindrical shaft that transmits torque from the engine to the wheels. They are most commonly found on rear-wheel drive vehicles and connect the rear of the transmission to the driveshaft. As the output shaft of the transmission rotates it spins the driveshaft, which then turns the differential ring gear to rotate the wheels.

Fault Feature Extraction and Diagnosis of Gearbox Based on

A gear transmission system is a complex nonstationary and nonlinear time-varying coupling system. When faults occur on gear system, it is difficult to extract the fault feature. In this paper, a novel fault diagnosis method based on ensemble empirical mode decomposition (EEMD) and Deep Briefs Network (DBN) is proposed to treat the vibration signals measured from gearbox.

Common gearbox problems and diagnosis

Noise. Noise is the first warning sign of a transmission problem. The sooner the problem is caught and repaired, the better: fewer parts will be affected and any repairs will be less expensive. Bearing, gear and shaft wear are the most common causes of noise. As gear tooth faces and bearing races wear, they develop groves and small pits.
