I have an 82 300sd. Im not certain that its getting into 4th gear. At 55 to 65 its runnning 25-3000 rpm which feels a little high. Should it be lower? Gears 2-3 feel like mush going through them so I may be miscounting.

That's about right. High gear is a straight through gear, no overdrive AFAIK. Mine runs about 2700rpm @55 mph, about 31-3200 at 70. My car sometimes mushes through 2nd and 3rd also, so I know how you feel. I'm always checking the tach to verify I'm actually in high gear. I always am, unless I've bumped the shifter back...
