Yes. The plus and minus allws you to manually pull the transmission out of overdrive. Contact a Mitsubishi Service dept for specific details pertaining to its function(s).

Replace heater/ac control assembly

YOU HAVE TO LOOK IN OWNERS MANUAL OR FACTORY MANUAL IN GLOVE COMPARTMENT.IT WILL TELL YOU WHAT TYPE TRANSMISSION YOUR VECHICLE USE.IF YOU DONT HAVE A OWNERS MANUAL YOU CAN CALL MITSUBISHI SERVICE DEPARTMENT.THEY WILL LOOK IT UP AND TELL YOU.

It is inside the transmission, you have to get under the car, drop the oil , if it has a plug, or drop the pan, oil will leak for days, 2 or 3 bolts hold the filter in place, take out the plastic plug if you find one floating around in the pan, and put it all back together.

While I understand this answer may be overkill, follow this link to an article about the engine cooling system. Look midway down the article for this sentence "More information about 2003 Mitsubishi Outlander Engine Cooling System service and troubleshooting, find here – 32 pages of PDF filetype" Click on the "find here" link which will prompt you to download a file 14_rar. Open it with any decompressing software (Winzip, WinRar) to find 14.pdf. Go to page 14-23 to see a diagram of where water pump is. It will also give you instructions on removing and replacing it. Good luck!
