I believe those wires are for hooking up a tester to the transmission computer [ or transmission controller, whatever you want to call it... ]. I would look under the floorboard in the pedal area. You might have jammed a stick up under there, bent something, or pulled a wire off somewhere. The F pedal has a device that tells the controller to go forward, and it also lights up the F on the dash. So, there is no way you can go R until you get the F off... Either the pedal is not returning to it's home position, or back to the bent or wire off thing.... The wet oil thing underneath is probably something else....
