2nd-3rd gear grind? - Hyundai Performance Forums

crnrkiller · 09-09-2006, 07:37 PM

i have a 03 accent and did the tb bypass on it. When i am going from 2nd to 3rd gear at over 4000 rpms it makes a grinding like noise. I heard someone else had this happen to after doing this mod. Any help or ideas why/what could cause this?:ermm:

my '99 GSi does this as well, i just figured the synchros were not spinning up quick enough, or they're starting to wear out.

Redline MT-90 is your best option to try and stop that. Also check the adjustment for the shifting cables. I know a few XDs that had less grind after adjustments where made. Good luck. If the syncro is gone... thats not cheap. (Parts are... labor is not)

i've ordered Redline MT-90. I hope it will fix my grinding between first and second

How do you adjust the shifter cables?

I used MT-90 and synthetic Lucas Oil Stabilizer. Haven't had a problem for 75,000+ miles.

Question for Gimp.

I know the manual tranny contains just over 2 liters of oil. But how much oil stabiliser did you put in that 2 liters? It's not like I'll put 1 liter of oil stabiliser and 1.5 liter of redline...

It's just over 2 quarts, not 2 liters.

Lucas oil stabilizer pretty much says you can add as much as you want up to even running only the oil stabilizer in gear boxes, recommends 20% to 60% in an engine.

I won't run Lucas Oil Stabilizer though anymore because of this:
