Synthetic gear oil is goooooood.

I'm not sure if you have ever heard of this, but it is called GM Syncromesh. You can go to any GM dealer and pick this up. It is a little expensive, about $10 a bottle, but is well worth the investment. I put two bottles of this and two bottles of 80w-90 synthetic gear oil in my transmission after my clutch/flywheel install. Gear shifts are much smoother and putting the car in first gear isn't as tight as it once was.

When I had my clutch installed I had my fluids changed out. Super Blue for the tranny and Royal Purple for the diffs. and I couldn't be happier.

USE redline lightweight shock proof!!! You will LOVE it!
FYI: I'am pretty sure andrew at geartech uses this stuff in his rebuilds

i agree, redline in incredible. my 4th gear synchro grinded, i changed the tranny fluid to redline and it worked perfectly, the only thing since it is soo thick it takes a little bit longer to warm up, other than that it is great

the lightweight isnt as thick....i rocked it for a whole winter and was better then the stock fluid in the cold.

Yeah the blue stuff got rid of my fourth gear grind too, it's a wonderful thing to be able to shift into fourth and not cringe lol.

I'm using Mobil1, and with my WRX at 105,000 miles the trans still feels great.

no dont ever put synthetic fluid in your tranny, I had issues with that, my 3rd to 4th gear grinds on high rpm. UNCLE SCOTTY MIX FTW!!!
