If any of you guys sre getting notchy shifting from 1st to 2nd or 2nd to 3rd... it's quite normal.
As you can see there are two syncros on both of them. Some times they both line up when you shift and you get that smooth shift feeling, like a 3rd to 4th. Most of the time they don't line up hence the notchy feel.
If you owned a DSM before you know what I'm talking about.
As for the syncros grinding. I know mitsu syncros are weak . If you grind it once badly ...that's it. Most of the time it's drivers error and won't admit to it so they blame the trans.
When I first started do some fast shifts in my EVO. I would grind 2nd and 4th most of the time . I was pissed off . This never happened on my GSR integra. Then I started to adjust my shifting and got better at not grinding gears anymore. Well I still do occasionally I admit it's my fault.
I get a notchy slow shift at 1st to 2nd but I know it's the double syncro on 2nd so to me it's normal.
My suggestion to EVO owners that have grinding problems... try adjusting you shifting technique. If it still grinds....take it to the dealer--un-modded--.
I too had a share of problems ...5th gear grind at high rpm's. Last Oct. at 4500 miles. ( TSB wasn't out yet ) They tried to blame my cat-back but I didn't back down so they warranteed it.
Other than that ...20,090 miles no issues. Only driver error sometimes.

Have it checked anyway and have them document it on the repair order so if they found no problem in your trans, and all of a sudden your tranny took a **** after 10K or whatever.......they have a record of it.
Oh yeah.... go with them on the test drive.
Drivetrain is covered 5yr/ 60K miles for 03 models
04's are 10yr /100K I believe.
I know that this has probably been discussed, but I believe some of the problems being seen are caused by trans. oil. The right oil to use is a good question, and not exactly the point I want to make. What i've found (at least here in utah) is the dealers don't follow the service manual when it comes to drivetrain lubricants. The trans calls for a GL-4 grade oil, which has been proven to be a synchro friendly lubricant, the transfer case, and diff call for a GL-5 which is a little more viscious, and can cause quick wear on a synchro. When I called the dealers (all of them here in Utah) everyone of them told me they recieve their oil in bulk, and that they fill the trans. transfer case, and diff with the same oil, all of which is a GL-5. The service manual specifically calls for a GL-4. My theory is the oil being put in our trans may cause premature wear on the synchros adversly affecting the way it shifts.
I'll try and upload the exerpt from the manual....

Just to touch on my post earlier, here's some proof of the TSBs and warranty.

Thought I'd reiterate here as it's the topic at hand. Do take prints of these in with you if you're going to the dealer with grinding issues. Let us know how it turns out, too. Good luck.

Yikes.
Today I was driving my EVO back home from work when I noticed for the first time, a fifth gear grind like some of you are talking about. I kept shifting from 4th to 5th over and over and it was grinding nearly every time I shifted back to back, and I was shifting at like 4500!!
What the hell is the deal here. I honestly dont want the dealer to screw with my car, I'd rather do the work myself if they would pay for it haha.
Sometimes it will do the same from 1st to 2cd. I am going to check the fluid level and see what that looks like. When I say grind it i'm talking about you can actually fill the synchro not doing its job and it can kinda be described as a metallic smooth sound with some vibration in the shift knob.

I've had two builds on my tranny, once for the 5th than the 3-4 syncro. Seems to me, as long as I can shift properly and abstain from drag racing ,I'll be alright. I have to get Trix to rebuild it or Shep to rebuild it, but I really would like one of the shops to pacify me and say "This WILL work like a tranny is supposed to when we are done with it, no exceptions". I think thats hard with a rebuild, no?
I should have been more specific w/ my question. I meant "What is the build date of your car?" It says on your door jam. I'm trying to see if the 5th gear synchro issue only affects cars with certain build dates.
My '03 has a build date of 10/03 and does not have any 5th gear or 3-4 issues. I don't drag race or do any speed shifting w/ my car either. I just mostly commute w/ it so it hasn't seen too many redline shifts.

My Evo is an "03" and at 11000 miles it will grind if I shift into 5th at high rpm as in after using 3rd gear in a passing situation then shifting into 5th (at 80mph). I went through this kind of thing with my "00" Eclipse gt. In that car I had the tran.s syncros replaced under warranty at 400 miles and then again around 15k. With the Evo I am going to wait until it is really bad before I take it in. Mitsu 5spd.s really are junk.

Had my car since May 04., started grinding 1-2 around 1k miles, i recently installed a B&M SS with all the bushings and it actually helped it out. I have 7k on the car now no mods except KN drop in filter and this B&M SS. Im thinking of taking it to the dealer this weekend to see what they'll do.
