7 Speed Auto Trans Fluid Change

CyFi6

Just wanted to show an alternate way to fill the 7AT trans which I found to be a lot easier and less messy. There is a metal cap over what would normally be a dipstick on the right side of the trans that you can use as a fill port.

I bought some 5/8OD nylon tube from Lowes and a funnel.

Remove the 10mm bolt holding the cap in place and fit the tube into the opening from the engine bay. The 5/8OD tube is the perfect size.

Start the car up and move through the gears til you are at 104F temp on the transmission pan/fluid temp. Put it in park and leave the engine running. Remove the fill plug (make sure drain plug is installed) and place a catch pan under it. Add fluid through the funnel.

Once the trans is full it will start to come out of the fill plug and drain into the pan. At this point you can reinstall the fill plug and torque to 9 ft lbs.

Let the car cool and reinstall the "dipstick" cap.
