so the owners manuel says to put 3.0qt of oil in the car but reading some threds some people are saying to only put it in till it starts to flow back out but it starts to come back out at just under 2.75 and ive heard to overfill is bad so witch is it?

also i just changed my oil to ams because there was some grind problems. i removed the fill bolt first and oil started to pour out from there so i figured it had close to 3.0qt after it was all drained so i also put in just under 3.0qts but started to come out long before that.
anyway the grinding continued so i decided i needeed a new trans but someone told me to try bg syincroshift and im thinking to also put less in there? i dont know what to do less than 2.75 seems like alot less when your talking about only 3qts
anyone ever have bg syincroshift help fix there syincro probs?

 

The procedure for checking the level is there for a reason. Don't overfill it. Sometimes you can force a little extra in especially in the tcase. It can be hard to get all the air out and that can fool you into thinking it's full when it's not.

Run it for 50 miles or so and check it again. I bet your level will go down a little and you may be able to add more. Once it's ran for a while the oil works it's way in all the voids and the level goes down a little. This is especially true when filling the tcase.

Try some Amsoil MTG 75-90 GL4

well when you removed the plug and oil started to leak out, was that while the car was still hot? i heard that oild expands or something when its hot. try checking it when its cold. Also, my tranny has been leaking very slow for 10k miles now since my new clutch was installed. I have amsoil in it. Shifting was ok until about 8k miles later I started noticing grinds in 2nd, 3rd, and 4th at WOT, so i pulled the plug and nothing was leaking out. I filled it back up with about 1/3 qt of redline, and all grinds have disappeared so Im guessing amsoil with redline is a good mix...

 

dude thats what i just put in there it didnt help

no I made shure the car was not hot so i wouldnt burn myself at all.

so I should keep forceing it in till i get to 3.0qts?

 

but if its flowing out, then it must be over 3 quarts. after doing many searches, supposedly the tranny will leak any extra oil out until it reaches its proper level, but dont quote me on that. what kind of grinding are you getting? 5th gear is normal, and a notchy 3rd gear is also. Anything different than that is a concern in my opinion

 

A grinding 5th gear isn't normal. It may be a normal PROBLEM with Evo's, but its surely not normal.

If your car has a warranty on it, I suggest getting a dealer to fix it. I did and now my car shifts just fine. My car had 18,000 miles on it in when it was fixed in July and now has 23,000 and its been grind free since.

 

lol yea i thats what i meant, i guess i just got used to it. Ok its a known problem so it probably isnt a result of ur choice of tranny oil. the dealer in my town wont touch any evo that has anything not oem, but i heard a couple dealers in LA will fix the 5th gear for free. its just a hassle to put life on pause and leave my car 2 hours south at the dealer and not know when to pick it up and all that. How long did they take to fix urs and was there any charge or did warranty over it 100%?

 

so would there still be about a 4th of a qt left in the trans after you drain till it stops driping?

 

This is a stupid question, but your car was level during filling/draining, correct? It needs to be level during draining and filling; if at an angle, it needs to be the correct angle. If you don't know what that correct angle is then I suggest 0* angle while draining/filling.

A couple things to be cleared up in this thread:
- It shouldn't really matter if you "overfill" the trans as it will be extremely difficult to put too much excess since you're fighting gravity while trying to cap the fill plug back in there - unless your car is at an angle.
- There should not be much excess oil in the resevoir when you drain till it stops dripping - unless the car is at an angle.
- Grinding gears is not normal. Even if your car is at an angle.
- Everything expands when it is hot. That is the way the universe works.
- If your tranny is grinding after 18k you either live in a harsh environment or you (or a previous person) treat(ed) your car harshly.
- You can force 3.0 qts if you want, but if it is full before then, you're just spilling excess out. One thing to check (if your car is level): If you are using a tube to fill the oil it could be more than 90* off the opposite wall of the fill plug, which will force some oil to come back down the tube and out, which could be seen as "full." Best bet is to make sure the tube is in the hole and pointing downward (less than 90*) a bit.
- Tranny shouldn't leak oil. Is it visibly leaving spots on the ground? You have a leak which is not normal. Did you get the gasket back on the drain plug?
- There will likely be a bit of air left in the resevoir. Fact remains that the fill line is where the fill plug is so that top portion will have air in it. Refer to above point about everything expanding when hot, including oil.

 

I laughed my *** off when I read that.

 

yes the car was level, it started to come back somewhere between 2.5qts and 2.75qts but i had a long gravity feed funnel with a tip that fit flush to the fill hole so i was abel to get close to 3qts in there i would say about 2.85qts then i did the switch indiana jones style with the fill tube and the bolt so hardly any driped out.
so im still not clear here im still getting mixed answers. DO I FILL TILL STARTS TO DRIP OUT OR DO I FORCE THE FACTORY STATED AMOUT OF 3.0QTS IN THERE?

 

will i guess ile just put 2.5qts in and cross my fingers

 

its difficult to get all 3 quarts out i imagine considering the weight of the fluid... yeah considering the level can drop slightly after driving, i personally would fill slightly more then what drips out by being fast hehe

 

Yeah, I figured thats what you meant, but I just wanted to point it out just in case.

I bought the car with less than 4000 miles on it and it was grinding. If I had known it was a issue with the 9's that would've been the first thing I checked when I bought it. My 8 never had tranny issues.

I went through this site and showed them all the other posts of 9 owners with this problem. I also called numerous dealers on the west coast to see what they did for the issue. Since most Evo's are on the west coast, I figured they would be doing more warranty work on them. I was right. I also mentioned getting a lawyer since they told me that my car still had the full factory warranty on it, but was telling me there was no fix. The calls to the west coast dealers confirmed that the fix was putting a new 5th gear synchro in it.

My car had 18,000 miles on it when it was fixed and it didn't cost me anything. My car had a intake, full exhaust, AEM wideband, and a AEM Tru-Boost. I put the cat back on and took it up there and it was fixed.

 

I answered your question re: 3 quarts. If you are filling it correctly (level, not having a possible issue of oil coming out prematurely) then when it is "full" you are simply spilling out excess. If it makes you feel better to keep pushing until 3 qts, even though you are spilling out .25 - .5 qts, then do it.

BTW - a tip that fits flush to the fill hole isn't what I would consider ideal, unless you know for sure that you are at exactly 0* or less, exactly. Gravity can be a beeatch when it comes to fluids, afterall. If you were at 0* and the rate at which the oil is traveling slows to almost nill, some of that oil could certainly start creeping the wrong way.

Some could say I'm talking about boundary cases, but I would rather be safe than sorry. Here is something you could do. Button it up for now and drive it to see how it feels. Once you've gotten a good amount of driving/shifting in, maybe after a couple days even, try to fill it some more and see what happens.
