      2013 CRV had to have converter replaced. Honda would not do the update for the vibration. I could only get them to replace the torque converter. Now the D light flashes constantly. How could it have already failed. The tech replaced the sensors while I watched. Can I drive it till I can afford to take it to a trans shop? Drives just fine so far but the D light won’t stop flashing. Fluid color is good.

        A new torque converter could fail due to a variety of reasons, despite being newly installed. Here are some potential causes:

        Manufacturing Defects: Even though it’s new, there could be flaws in the manufacturing process that compromise its integrity. This could include issues with welding, casting, or machining, leading to weak spots or structural vulnerabilities.

        Material Quality: Poor quality materials used in the construction of the torque converter can lead to premature failure. This might involve subpar metals or alloys that are not durable enough to withstand the stresses and heat generated during operation.

        Installation Errors: Incorrect installation procedures can cause damage to the torque converter. If it’s not properly aligned, secured, or connected to the transmission and engine components, it may experience excessive wear or internal damage.

        Fluid Contamination: Contaminated transmission fluid, either due to debris left in the transmission system during installation or from previous use, can cause damage to the torque converter’s components. Abrasive particles or improper fluid levels can lead to friction, overheating, and eventual failure.

        Overheating: Excessive heat generated during operation can degrade the torque converter’s components over time. This can be caused by towing heavy loads, driving in stop-and-go traffic, or operating the vehicle in extreme temperatures without proper cooling mechanisms.

        Excessive Load or Stress: Subjecting the vehicle to conditions beyond its design limits, such as towing loads heavier than recommended or driving aggressively, can put undue stress on the torque converter, leading to premature wear and failure.

        Fluid Leaks: Any leaks in the transmission system, including seals or gaskets, can result in low fluid levels or pressure, causing the torque converter to malfunction due to inadequate lubrication or cooling.

        Electronic or Control System Malfunctions: In vehicles with electronically controlled transmissions, issues with the control module or sensors can result in improper torque converter operation, leading to failure.

        Vibration or Imbalance: Any imbalance or excessive vibration in the drivetrain, such as from worn or damaged engine or transmission mounts, can cause damage to the torque converter over time.

        Manufacturing Tolerances: Even if the torque converter meets specifications, there can still be variations in manufacturing tolerances that affect its performance and longevity.

        Overall, the best option is Book your ride from home and enjoy.

          Thanks for the reply. Shop replaced all solenoids on trans, kept getting converter error code. Took trans apart and saw nothing wrong. They gave up and put in a rebuilt trans and it works with torque converter that honda said was bad and should be replaced for a 3rd time. lol
