I just need to know what kind of transmission fluid i need to put in. in a Mitsubishi outlander 2003

No they are crooks! The genuine part from Mitsubishi is $120 and it looks like you could do it yourself.

Where is the transmission fluid pressure sensor? The pump pressure switch is located on the transmission housing next to the pump. The switch lets the computer know what the pressure is coming from the pump when the engine is running. The servo pressure switch is located on the housing near a band or servo in the transmission.

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.

you have to remove the transmission fluid pan-it is not an external filter
first remove the transmission drain plug and then remove the pan-you can then remove the filter and transmission pan gasket

There are shops that will do a complete package deal. You might be cheaper in do one of those. It is recomended to do all the maintanence, you have to look at it this way, An ounce of prevention is a pound of cure.

Engines get tuned up. Transmissions get the filter and fluid changed. The auto parts store guy misunderstood what you want to do.

It is on the right hand side near the front, over a foot down into the engine compartment (toward the ground). It has a blue cap on it and says ATF on it.

use the dipstick hole, you need a certain funnel. if you cant fiind it let me know.
