^^^ Me too, but I already did buy the car so I'm just crossing my fingers that I don't have any issues! This has definitely changed the priority order of my future modifications. I think that I will change the trans fluid, swap out the flywheel for a single mass type, and try to get as much of the rev hang tuned out as possible. Of course, I will most likely wait til I get even a hint of a problem before doing this and consult with the dealership first.

^^^Wait on the clutch/flywheel mods until the tranny issue is resolved so the stealership doesn't try some BS.

What ever is causing the grind, it shouldn't be there.

Me & DD have been discussing this in the Hyundai employees forum & I mentioned that my shop forman talked to Tech Line today & they do know that there is a grinding issue with a few of the M/T units & are working on it. Give them some time to figure it out. As of right now they are recommending fluid exchange with Red Line 75W90, but let the dealer do it. If you actually have the problem, take it in so it can be documented & let them talk to Tech Line to follow procedure.

The less mods you have the better, but I don't see where any of these mods could be attrubuted to this concern, esp considering there are others out there w/o mods complaining about the same thing. Just don't do any mods to the tranny & keep overall power output levels down if possible until this is resolved.

I hope that all this is taken care of B4 I take possession of my car....LoL

Good pointers Tufast. I definitely planned to wait and see while putting some more miles on my car and accumulating parts for the next stage of the build. I'll have to put in a call to my Hyundai dealership and see if I can schedule a transmission fluid change for now.

I think the poll was a bit mis leading. I'm having the grind issue when shifting INTO 5th gear, FROM 4th. IMO I would classify this as a 4-5th grind. which is not listed on your poll. I'm guessing your poll is suggesting "5-6th" as grinding when shifting into EITHER 5th or 6th gear?? but I'm not sure.

In summary, I brought it to dealer, they looked at it, had a hyundai field engineer come look at it, and now they are replacing the entire transmission under warranty. so not THAT big of a deal. as long as you haven't voided your warranty already....

Yeah, the most common grind issue is going from 4th into 5th or different issue when slowing going from 3rd to 2nd & 2nd to 1st.

The M/T we replaced for the same issue you just had yours replaced for is being looked at internally now by Hyundai to try to figure what improvements need to be made I guessing.

I have occasional grinding up into 3rd and up into 5th (2nd to 3rd and 4th to 5th)

If I shift slowly there are no problems...

+1 on that. If I do it slowly, I get no problems. if I shift like normal, I'll get the 5th gear grind regularly. As far as downshifting goes, I don't do it too much here because I like to roll to a stop, I usually get plenty of space when I hit redlights.

this problem will need to be completely resolved before i purchase. i dont see why they can't resolve it but if they don't i'll have to settle for a WRX.

Just an FYI. EVO X has grinding issues also from 2nd to 3rd and 3rd to 4th. They claim that is gets better with time/miles. I think tranny fluid change helps some also. So Hyundai is not the only one with this type of issue.
