Where to put in the automatic tra...

I own a 1994 BMW 540i with an automatic transmission. The filler hole/plug is located under the transmission oil pan. Picture in your mind an inverted cone with a hex plug inside the top of the cone. You will need to remove the plug and pump fluid into the pan until it overflows. Also, this must be done with the engine running and the transmission in neutral.

Do not try this unless to you have the proper equipment to raise your car, keep it level, and have four jackstands in addition to the special fluid and pump.

its on the side of the box . should look like a hex drive bolt
