Hello Erick,
These standard transmissions are designed to run with automatic transmission fluid. I have always used ATF.

Agree with Joe,

You should use ATF. A Mercedes mechanic warned me that normal gear oil could damage the gearbox (there are some ball bearings which are not lubricated with the thicker oil)

Anyone know why you're to use ATF and not gear lube? There's an actual reason why.
