Hi,
I want you to try something. I don't think it's the transmission. Instead, I think it is related to the clutch. Don't laugh, but make sure the brake fluid is full. The brake master cylinder functions as the clutch master cylinder reservoir as well as for the brakes.
Next, with the engine off, see if it shifts through the gears easily. If it does, it is most likely related to the clutch master cylinder or slave cylinder.
Let me know.
Take care,
Joe
