In 3rd and 4th gear between 25mph and 30mph what RPM is the engine at? Are you trying to accelerate at that speed in these gears?
I ask because in my five speed car, 25mph to 30mph is where I shift from first to second. I think you're shifting too early, and lugging the engine.

Yes, the roughness is happening in 3rd gear and then disappears once in higher gears. What did you mean when you say "the gear is on its way out".
How does the engine sound/feel between 4k and 5k RPM in third and fourth gear?
