Hi Guys, So i am trying to change the transmission fluid in my 03 Lancer ES, i went to the store and bought the filter (looks just like an oil filter) and bought 8 quarts of transmission oil. I found the drain plug for the transmission oil, but i cant find where the transmission filter is!

Any one have any idea, i tried doing a search for this but came up with nothing. Thanks for your help ahead of time guys!

 

U have an automatic right?
if yes the filter is internal. You have to buy a new gasket for the transmission pan. so U drain all the tranny fluid and drop tranny pan and the filter will be inside. remove old filter and install new filter. clean the pan out and there should be a magnet inside the pan make sure to clean that also. any gasket material on pan should also be cleaned off to insure a good seal with the new gasket (do not scratch the sealing surface's!!!) also make sure before U drain the tranny fluid get your car up to operating temp before starting.

 

Does any one have any pics of the how to replace the filter? I can not seem to find any info in the manual on CD I bought

 

what kind of tranny fluid are you using???? i need to re-fill mine after replacing axel. would like to know asap, thanks!

any pics of how you drain/fill it?? thanks!

 

Use Mitsu ATF III available @ the dealership of course. And sorry to tell you, but all auto store computers list the incorrect trans filter. The trans filter is a thinner, narrow pan-like filter...not a circular screw-on one. I tried finding a pic for reference, but of course I can't remember the site. But all the items can be found at the dealership or online too.

 

BUMP, Does anybody know which line is it to disconnect to flush the automatic transmission fluid? Looking from the drivers point of view , which line is it, the left or the right one? any help is appreciated

 

i thought we have a sticky in the how-to section? i swear i saw it like 4 yrs ago, and that's how i did my transmission flush in my auto. the filter is a bi$$$. you need to remove like 16 screws to gt to the filter. gl getting the info, looks like they remove that sticky

ummm here's an old thread:

There is a drain bolt behind the driver's side wheel! I believe it's a 21mm?

 

Geez, we need pictures because my tranny is messing up and now I think I know why. I had my fluid changed at Tire King. and I think they put the wrong fluid

 

did you ever end up finding out how 2 change the external?

i have both filters but idk where the external goes.. so confused

 

there isn't an external filter

 

I have a Mitsubishi lancer 2003 ES and im Wondering if someone can tell me what type of oil I need for my transmission( specific and the most up to date version).
What kind of flush should I get for the trans? Asap????

 

DIAMOND ATF SP III is OEM fluid, and is recommended...an SP III equivalent will be better than nothing if your oil is really bad...
