searched but wanted to asked a couple questions
2006 evo ix 5 spd, racing today and when shifting into 5th at over 5500rpm it grinds, im guessing the synchro is bad right?
what kinda dollar amount and what are my options for the fix?
(not mitsubishi out of warranty)
was there a TSB that mitsubishi will fix for me out of warranty?

thanks guys

 

i read people switching to pennzoil synchromesh to help the problem, does that sound right?

 

5th gear is known to evoix to do this mine does it not much you can really do about it unless you get new ones. if going oem yea will happen again. i would just take it easy in 5th and save for a built trans :P i give it about a sec before engaging 5th but i dont slam it either and will go in with out grinding.

 

I have the same problem. I just don't get on the 5th gear. But pennzoil synchromesh really help. It will not get rid of the problem but it will lessen the grinding as I noticed that

 

Save up for a Shep Trans, will cost you somewhere around $1000, plus anywhere from a $300 to $700 dollar labor count. Don't do a shop rebuild, because no shop wants to be held accountable for any issues they might have after resembling the tranny just to fix a synchro issue. Most reputable shops (who know what they're doing) will want you to replace everything. The lowest quote I got was $2100 :-(

 

I had TRE do my trans which was $1500 also $500 labor i paid to the shop for removal of the trans.

 

My '06 IX 5th grinds too. I searched and the Evo III have a TSB for it on their cars, but I couldn't find any on the IX.
Seems funny that you guys have problems with it too.........

 

mine grinds little bit but only when at WOT racing and sometimes not always

 

often times high rpm lock out can be tamed with a twin disc. My stock clutch would never allow high rpm shifting..twin solved that

 

mine's been grinding for two years now... I just take it easy in 5th, let the rpm's drop for a moment then shift....

someday I'll get the shep rebuld, seems like the best option.
