I just got a '93. Grainger said API Service GL-4 or GL-5 SAE 75W-80. I went to a couple parts stores and nobody had any, although 75W-90 was available. Should I keep looking, or go with that? I live in Texas, so it gets a workout in the heat. Thanks!

Get Redline synthetic, either MTL-90 or 75w-90NS.
I second this. My tranny has smoothed out a fair bit once I switched over to Redline.
