Where is the transission filter located on a 2002 mitsubishi galant 2.4 liter and 4 cylinders

The firing order should be 1 2 3 4 5 6
Your cylinder banks are odd and even numbered.
Looking under the hood, front bank of cylinders , from left to right, 2 4 6
The rear bank of cylinders, left to right, 1 3 5

the location is in engine compartment, there's 2 fuses one of left, one of right, the one of the right is the fuel pump relay, they are the closet relays to the headlights

Check the cam & crank position sensor. Then look at the Throttle position sensor. Finally check for intake leaks.

its behind the timing belt down by the crank pulley. Basically you will need to remove the timing belt in order to replace

4 cylinder? under the timing belt cover down behind crank pulley.

The starter is located on the side of the engine, follow the positive battery cable down to the starter, it is a round cylinder usually held in with 2/3 mounting bolts and is approx.6"round diameterX10" long.

I am not fanmilar with your specifdic car but generally the catalytic converter is located just down from the engine's head pipe. The head pipe is the opne that bolts to the engine cylinder block

well thats a good question. the sensor may be ok and your engine is running lean, or the sensor is bad............its possible that its bad, but I would want it checked by a qualified repair shop first, you dont want to replace parts because you THINK they are bad, that just costs you even more money. The upstream is located in the bottom of the exhaust manifold. if its lean found out why..... vac leak?

have the engine light code scanned, and it'll tell you if it's bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1, bank 2 sensor 4.

Bank 1 is on the same side as Cylinder 1
Bank 2 is on the opposite side of Cylinder 1

Sensor 1 is located before the catalytic converter.
Sensor 2 is located after the catalytic converter

my 02 galant is leaking but all fluids a full
