Looks like someone replaced the drain plug with maybe a trans. Temperature gauge?

 

Yea, looks like that is a temp sensor.

 

look guys,i got my evo brand new from the mitsubishi store,and i didnt changed the fluid,nobody did.this time im going to do it first time thats why im shocked why it looks like.so i should never mind about the wiring just do it like said before...
right?

 

sure it look like some sensor but ,i dont have any gauges?maybe the wiring its just prepared just to plug in and i can have temp or pressure gauge..?

 

All I can say is that on my car, which I bought new from the dealer also is that the trans fill is not a connector bung or a bolt. It has a 3/8 hex, so you need a 3/8 allen wrench or male socket to get it off. No open end wrench or regular socket.

 

derp.

 

if I were you I'd trace the wire back and see where it goes

 

OK,THE FLUID in tranny is succesfully changed,did it in my garage,bud i had problems to get to the fill plug in tran.case and unplug it,even i took off the underbrace.

 

did all the fluids change everything went well,im glad,i have time for some time now.

 

if i were you like others said trace the wire back to see where it goes and if nothing else take it back to the dealership and see what they say....

 

was wery simply job,with tha trannsmision,unpluged the wire,then the fill plug,did everything and at the finish,put back the fill plug ,and put back wires in it,the wire just pops on it like on headlight wires

and i really feel the car is more smooth,and the gears at first were even harder do shift sometimes but like after 50km,or 70km its without any force ....

 

good to hear then . but i would still try to find out where the wire goes though.

 

+1 lol crazy euro spec evos..lol jk
