GM Syncromesh is way to thin to run in the DSM Tranny. I know there are people that do, I have, shortly followed by a destroyed tranny. Every case I know where it has been used has ended in failure. Neo is said to be decent, a bit overpriced but it has a good rep. It does however come down to opinion. Redline is excellent fluid with an amazing rep, I would have to see some proof that Neo was better to justify spending that kind of money. Proof in the form of 3rd party studies. Just a couple well knowns using it isn't proof IMO.
