well, first off, dont even think about using a GL-5 fluid. just the thought will corrode your synchros.

use a GL-4 fliud, perferably a redline oil. MT-90 is good.

Hey man,

I flushed my cars transmission about 6 months ago and refilled it with Redline MT-90 fluid and I have had no issues with grinding or anything since then. I'll even help you out. Go to Myoilshop.com and enter the dealer code 675421 for a 10% discount off the whole order. You'll need three bottles.
