This is pretty simple, but I figured since there wasn't already a write-up, I'd take a couple pics of the job.
Items/tools required: Jack & jack stands
8mm hex key
Funnel w/ tubing (preferred)
2.1 quarts of your favorite, fully synthetic MTX fluid
I bought some BG Synchro Shift II, I swear by it- it'll make your transmission shift like butter. You can get it at Mitsubishi dealerships, or online
1) First off, you'll want to jack up the driver's side of the car (You'll get better results draining the transmission if you just jack up this side, as the drain plug faces the passenger side). USE JACK STANDS!
2) Here's a picture facing the transmission from the front of the car. Using your 8mm hex key, check to make sure you can untighten the fill plug first. Just crack it loose, but don't unscrew it.
3)On the left side of the transmission, just in front of the rear motor mount, the drain plug resides. Use the 8mm hex key and unscrew it.
4)After it has completely drained (approx 5-10 mins), tighten the plug back on. Make sure it's snug and a little extra, but not he-man tight. [strongman]Now use the funnel and tubing to fill the transmission from the fill hole. Make sure you use 2.1 quarts. Yes, that means having to buy three. [bigcry]
5) Tighten this plug down the same as the drain plug, lower the car, and enjoy your smoother-shifting transmission. [burnout]
Yes, same for the 2.3. If the maintenance calls for only once every 100k, I'd imagine the fluid would be in sorry condition once actually changed.
Of course, the harder you beat on your car, the sooner your fluids should be changed anyway. I'd be hard pressed to push any fluids further than 50K miles, unless it's the power steering. It's up to you, really. Some people like to change out their fluids more often and others have no problem running their oil dry.
On my evo, I used to change the transmission fluid every 3rd oil change, which was every 10-12K miles. There was always some metal deposits on the transmission magnetic drain plug. I realize all transmissions are different, but you get the point. Some people feel that transmission fluid should be changed fairly often, others think it can last 100K. Since it's a major drivetrain component, I'd feel it's crucial to keep the fluid in good condition.
SaleenN2O, if I had your car, I would probably change it. I feel you'll notice a difference, especially if you use the fluid I recommended.
damn man, every 3rd oil change?? that baby musta been SPARKLING!! [grinking]
i hate when i am at a drive-up window, and i shift from 1st to neutral, and then back to 1st when pulling out, and i can hear the shifts. my last car you never heard that, and my 2 previous were autos. makes me nervous, hearing those gears!
