All the way to the right you will see the 24mm socket you need. It's a shallow socket and you may need to get a pivot-head breaker bar as in my other picture below:


It's a very tight squeeze with these as well but once you crack it free, just slide the socket/bar off and use your finter to loosen the bolt.

DO NOT JUST TAKE THE BOLT OFF QUICK!!! OIL WILL GO EVERYWHERE.

Hold the bolt over the hole and allow the fluid to drain slowly and in a controlled manner.

^It wouldn't hurt and your gear box would benefit from the synthetic switch early for the long run.

I do mine every 30K on the dot, no later.

Hey I just did this but with Amsoil 75-90. For all of you who did this switch with both Amsoil and Redline MT-90, when did you feel the difference in the smoothness of the shifting? Was it immediately after changing the fluid, or was it as you drove the car around for a while?

Mine was after a few miles of driving around and shifting a lot. I would say that after about 10-15 miles I began to notice the shifter sliding a bit smoother. Basically, wait until the fluid is allowed to "touch" all of the gear box internals and then the shifting will become a bit smoother. Take the car up hills and over bumps so that the fluid can slosh around a bit in the gear box.

ok thanks because I took it around the block, (no where near close to even 1 mile) and I didnt notice any difference. I even went through all the gears before I turned the car on after the fluid was changed. I drive 280 miles/day so I guess ill definitely notice it tomorrow...

I have tried MT-90 and Motul Gear 300, and I don't think there is any difference in shifting smoothness between stock oil and synthetic oil. The only thing I could notice was with the Motul Gear 300. It was a lot easier to shift in the morning when the car was cold, than either stock or MT-90. But that's probably because the 300 is a slightly thinner oil.

Having said that, I thinking using synthetic fluids in the tranny and engine is a very good idea, especially if you go to the track or just drive your car hard. Just don't expect a big change in shifting smoothness.

yea ive actually driven around with the Amsoil gear lube for about 2000 miles now and I mean the only thing I can say is it's easier to shift when the car hasn't warmed up yet in this cold weather. Other than that I'd say the shift feel is basically the same as the stock oil.

im going to buy the redline gear oil later and do the change...getting into reverse and sometimes 1st is hard..but once it warm up it fine..but i just wanna get rid of the noise when you shift..this stuff is suppose to let the gear go in smoorth so your not forcing it...but i dont use the clutch when i racing only when im getting into first gear did i say racing or should i say shifting fast..

Is it safe to use MT-90 for limited slip differential or should i get some Redline 75w90 and their friction modifier for LSD? I'm not sure what dealer put in there but I know its 80w90. I think its too thick and I really like Redline.

^The difference in 80W-90 and 75W-90 is negligible other than on cold starts. As soon as it gets to operating temperature, they are the exact same viscosity.

The friction modifier though, I'd use the one that specifies that it has it.

If the engines "warm," it'll help to make sure as much of the old fluid comes out as possible. When warm, the fluid flows much easier so, more fluid will come out in less time.

when you remove the reverse sensor plug do you have to remove the scew also or all you need is to remove the reverse sensor to fill..

then i would neeed 24 mm to remove the drain and fill plug correct
