It seems that a lot of us are having transmission problems today. It could be temp related as the weather just turned cold. My S14 SR20DET has suddenly become hard to shift. First gear at dead rest is the hardest. I've checked the clutch fluid. I replced transmission fluid 1 yr ago with redline MT 90. The old fluid was pretty clean. Should I replace it again? I've noticed a red hose on the side of the transmission that is not hooked up on one side. What is that for? You can see it in these eBay photos.

I'm worried I may have bad synchros. Are S13 and S14 transmissions interchangable?
