Can a bad torque converter cause a transmission leak?
A leaky or damaged torque converter can cause a serious transmission leak. Under extreme or prolonged use, transmission fluid can overheat and even burn. High temperatures cause the fluid to oxidize and lose its viscosity. Overheating can occur during stop-and-go traffic, hot weather, street racing or when towing a heavy trailer.
However, depending on how overfilled it is, the leak could cause damage to both seals and gaskets from the fluid trying to find a way to escape. To fix it you’ll simply need to drain some fluid by partially un-bolting the transmission pan until the fluid is within the proper range.
