5th Gear Grinding
I have a 06 IX with TBE. When I'm on the highway over 60 MPH my 5th gear makes a grinding noise. Normal street driving there is no grinding when going into fifth. Also there is no problem getting into gear. Is it my syncro or is it my stock clutch?
Thanks in advance.

I have a IX and had the same problem. Its a bad synchro which problably ruined your whole 5th gear. Mitsu replaced mine under the warranty. 3rd thru 5th sychros and a new 5th gear. Here is the thread: https://www.evolutionm.net/forums/sh...d.php?t=249557
It will be covered under the warranty. Just sucks that your car's tranny has to get opened up like mine.
My 5th gear is now perfect. I still get the clunking, notchy feeling in 3rd. Good luck

^^ I have had the fifth gear grind since i bought my IX and drove it the first week i had it. Since then i have just kinda dealed with the 5th gear grind. Although, the stock clutch finally gave out earlier this month, so i replaced it with a new ACT street clutch. For the first week i had the ACT clutch it was working well, but i still had the 5th gear grind. Unfourtanetly now, my reverse is toasted somehow, and it will not go into reverse. I would hope mitsu would cover my reverse/5th gear synchros under warranty, but i have a modified clutch now.......so what do all think? im stuck without a reverse gear!

^^ Stock clutch went out at 9k, had 400miles on the new ACT clutch before the reverse locked up. So an MBC voids the powertrain warranty? Mine is pretty hidden.

I have a question about synchros on the IX. Ive heard that the reverse gear is a straight gear and has no synchros, is this correct??? If so my reverse locked out wouldnt be the synchros then. Any help appreciated.

Yup, Common on are cars...my 5th had that problem then 5th gave out on me while I was at the Redline time attack... then I took it to Robispec 
and now it's smooth and a stronger tranny.

If you only have a 5-speed...it might be that you are shifting too soon...5th gear is a really tall gear...because it's basically overdrive for the highway...I always let the RPM fall a little around 3500 before shifting up to 5...maybe it's the right thing to do...or maybe my Trans is f%$k'd

I had luck with my warranty claim. BUT...I have heard horror stories. Your exhaust cannot cause synchro and tranny problems. Probably don't have to take the exhaust off but it wouldn't hurt. The less they can point the finger at you abusing the car, the better. Mitsubishi knows about this grinding problem in thier trannys. It's BS that half the IX's on here have some sort of tranny/sychro/grinding issue (imo).
