Doesn't the drain plug have a magnet on it.........? Pretty sure my old Land Rover gearbox did.
yeah, this doesn't

Best fluid yet, and i have tried a few different fluids, try Redline MT-LV gear box oil, the only one that stopped my crashy 2nd gear.
Comes 1 quart and just enough to fill the box.

The first time i drained the oil i had access to a ramp. The ramp owner fixed Land Rovers.
When we drained the gear oil, he said that it looked like Landy auto transmission oil. He showed me some he had in a drum.

Perhaps something BMW took on from their Rover days.
