[EcoCivic]

Hello everyone, I am wondering how much power a fully applied torque converter lockup clutch will hold before it starts to slip or suffers other damage.

Long story short, I installed a manual lockup switch in my 05 Civic, mainly for performance reasons. With my old trans, I would lock the converter at full throttle for better acceleration. However, I have my doubts about if doing so is good on the TCC.

The TCC is (on my car anyways) only designed to lock under light to medium loads in 3rd or 4th gear, so I don't know how good it is on it to hold the engine's maximum power. And to make matters worse, I added around 30 HP above stock to my engine.

So how much load can the TCC safely handle? I imagine it can't handle maximum power since it was never designed to be applied under heavy loads let alone full throttle, and especially not with the extra power I added to my engine. Is this something I need to worry about?

Thanks in advance for your opinions!
