Tranny fluid change
three words ladies and gentlemen.
mobil
one
synthetic.
after 4 hrs of making sure i knew what i was doing and taking intakes off and splashguards and using a jack and jackstands,
i changed my own tranny oil.
it was a pain, but i suck.
though the benefits were more amazing than i expected.
i feel like i just bought my car. the shifting is so smooth its like im playing a game.
seriously, if you are near the 30k mark. mobil one synthetic, 75w 90, i PROMISE you will not regret it.
it was 10 a quart at pep boys, just a heads up.

I see that the Mobil 1 gear oil is GL5 rated. You want to stay away from this as the GL5 contains sulfur additives for extreme pressure lubricant. The sulfur is quite hard on syncros reducing life by 40%. Might want to check with Mobil 1 to see if they use different additives that are safe for syncros. Syncros require a GL4 rated oil.
You may want to check out Royal Purple 75 90 GL4/GL5, it does not contain sulfur and is safe for syncros. Some people do not like the way it performs. I run it, but its not very smooth on those cold mornings, shifts good once warmed up though. As well Redline makes a 75 90 GL4 but I have not used it so I cannot comment.

but i was running on 45k with the stock fluid... so anything might have been better.

another problem is Mobil one doesn't have a friction additive needed for shifting at redline or FF shifting. If you experience some grind or "lockout" when power shifting you may need to use an oil with the friction additive like redline MTL, MT-90 or syncromesh. I personally use MTL in my evo's and MT-90 in my subies.

Hey Bro, change that oil INMMEDIATELY, is not good for our tranny. My synchros fell victim to it, and now my tranny is broken, do it now while its new, even if you loose the money, better 20 bucks, than 900 on a new tranny.
Like the dude said, it lowers synchros life away, my 3rd and 4th gears wont engage, pretty much at all, due to bad synchros.
Use either Pensoil Synchromesh or the better Royal Purple, SynchroMax. I personally now use Synchro Max, and even with the damaged tranny the car shifts way better, it will even engage the bad gears here and then

Not to scare you or anything, but it starts by feeling 3rd a little rougher when you shift to it, then starts grinding a little, which it woill always do. I think my problem has to do more with the shift linkages inside the tranny more than synchros themselves, but it started by changing to Mobil 1 gear oil synthethic.
But my break down has to do more with the fact that my pressure plate lost its bearings and wasnt holding
