Argument: To flush or not to flush an MT

[entirelyturbo]

Alright, guys....help me win an argument. You don't flush out an MT on our cars or any MT car for that matter, right? It works along the same principle as the engine or differentials. Drive it around first to heat up the oil so it will drain easier, and it should collect any metal shavings or whatever's in there on its way out. No flushing. That's AT...

Right?

No, you don't flush a MT car.....lubrication is done through the gears splashing around in the oil and carrying it to the upper gears.

I have heard of draining the gear oil and running ATF for a little bit. It is supposed to clean out any gunk ect. Then of course drain and refill with gear oil.
