Post Tranny oil changed !! Need advice

Want to change my tranny oil. How hard is it? What tools do I need to get it done? What type of tranny oil do I need/use? What oil weight do I need to use? Should I use Redline? or general oil?

Thanks --

Thanks for the advice guys! I will take my car to be serviced soon. It's hitting 3K miles already. And want to do an oil/tranny fluid change to clean all the debris out.

Thanks --

:-)

If I were you, I'd wait a while longer to do the tranny. Mine didn't get loosened up good until about 10,000 miles. I switched to Redline Synthetic 75-90NS close to 15K mi. The drain plug is magnetic, so it's not likely that chunks of metal are going to be flying around in your gear box destroying things.
It's not hard to do yourself. Just pull the drain plug on the bottom of the tranny, clean the gunk off the plug, and when it's done draining tighten it back up. If you do a search you can probably find the torque specs for that bolt. The refill tube and dipstick are on the passenger side under the large plastic box near the throttle body. Be carefull not to over fill it.
Good luck

I switched to Redline oil during my last change. At first, I LOVED it. Seriously, it feels a LOT better than whatever is in there, stock.

But now, I am going to switch back to the stock formula. Why? Because Redline is so damn slick, that I can push my tranny into gear when I shouldn't be able to, normally. I can grind the gears cause the synchros don't have time to spin up. Too slick for me.

Question

Which formula of Redline did you use? The NS designated oil should create enough friction for the synchros. I've had mine in for about 15,000 miles now, and it still works great.

Not to long after I bought my car (Maybe 15k into it), I switched to Redline 75W90 High Performance Tranny oil. Then at around 60K, I switched back to stock tranny oil due to something I read on the SVX board about synthetic oil caking the tranny mechanicals causing slippage.

Then I just figured synthetic tranny oil is made for the transmission so last Monday I switched to Mobil 1 ATF. I just feel more comfortable with synthetic oil. I haven't noticed any performance gains/losses switching from one oil to the other. Well, maybe the Mobile 1 ATF had something to do with me getting my best 1/4 mile times ever the last week or so. Hrmm...I don't know.

Also, if RalliSpec use it, than it must be good. ;-)

we're having two conversations here - I think.

Some people are talking about the manual, and others (wait for it)...the auto.

I've had both, and the Mobil1 ATF is good stuff. Best to get your whole system flushed, though, and at some point, a tranny cooler put in. As for the 5spd, I use Mobil1 75w90, and my gearbox does cruch a little, but I always rev-match and double clutch, so I wonder whether it IS really a synchro issue or not. Does anybody get "perfect" engagenment with the NS oils? I'd switch now if that's the case. I just thought the crunching was a Subie shortcoming.

I had the Redline 75W-90NS in the 98 tranny before. It was too slick and I always grind my gears 3-4 and 4-5 above 3.5K rpm.

Now, I used Mobil 1 75W-90 all around, and no grinds through all gears at any rpm. Shifting is also improved by large.

Yes you definately need to change your tranny fluid sooner or later. I say go with something synthetic. I've heard good thing about Redline. I personally won't change it myself. I am going to take it to a professional that has a machine that flushes out old tranny fluid for new stuff. When you just pull the tranny plug, it doesn't remove all the old fluid!
