While the transmission is operating, the flex plate that connects the torque converter to the engine crankshaft is constantly flexing and is subject to _____________.

While the transmission is operating, the flex plate that connects the torque converter to the engine crankshaft is constantly flexing and is subject to _____________.

• A. Cracking
• B. Slippage
• C. Rotating
• D. Leaking

Answer: (A)

The key idea is that the flex plate is subjected to repeated bending and twisting as the engine and torque converter interact. This cyclic stress causes metal fatigue, so tiny cracks can form and grow over time, leading to cracking. Slippage relates to friction surfaces and power transfer, not the plate itself; rotating is just normal movement, and leaking would involve fluids. So, under constant flexing, cracking is the expected failure mode.
