Grinding in 3rd and 4th
Since I bought the car I have had some minor grinding when shifting to 3&4. It's only a split second when I'm throwing it in place and only for the first few shifts, until the Trans warms up. This weekend I replaced my transmission fluid with redline mt-90, because I heard it was good for Grinding gears. Could this be something else? I already suspected that the flywheel has something wrong with it so I have plans on putting in a new clutch, flywheel and TOB. Will this solve it or should I just look for a new transmission?

I agree with flash its typically the most common problem because of the NLS feature.
But I am curious if you have an aftermarket shifter or not? and if so is it aligned properly?
I had a similar issue on my old ss/sc with a hurst shifter when i first bought it and it just needed some minor adjustments. Here is the thread i found and used when i had my grinding issue. https://www.cobaltss.net/forums/08-1...inding-187224/

It was Grinding before the mt+90, so that is irrelevant. Stock shifter, haven't picked a short throw yet. I used the mt-90 because it is supposed to have better lubrication properties that reduce grinding.

So, wait until the car warms up before driving. lol. I have the same problem with my eclipse grinding. If I take it easy it doesn't grind between shifts. Synchros going out are a common thing. Not sure how handy you are but if you have access to some tools like a press, a feeler gauges, torque wrench, sockets & ratchet... you could probably replace the synchros yourself. Or buy a used trans or have yours rebuilt.
