My rear spoiler will not retract

The car's system may interpret the transmission leak as a failure and keep the spoiler deployed. I've read it's happened with caliper failures, so this could be similar...

Using a long, narrow tool, like a screwdriver, release the shift-lever by inserting the screwdriver into the little rubber flap, right below the 'D' (drive) position indicator on shift panel (and toward the rear of the shift indicator panel) and stick the screw driver (or whatever) about 1/2 to one inch in and and probe around until you find the release for the shift lever. Then, while holding down the release lever, slide the shift lever into neutral and lower the spoiler; raise the top, roll the car around, whatever you want to do.
