If it is a 5 speed, the heavest is 75W85 (GL4). The 6 speeds can take up to 75W90 but they recommend 75W85. If you live in a cold area, the problem may be caused by the gear oil being too heavy which will make it hard to shift. If that is the case, use the 75W85. Also, if you are in a colder area, I would recommend a synthetic product. Conventional oils seem to get thicker in cold weather whereas synthetic won't.
That is my only recommendation. If you have the 5 speed, they used the wrong oil. Don't panic, it shouldn't hurt anything, but should be changed. If that doesn't help, then try this. With the engine off, does the trans shift easily into 2nd gear when cold? If it does, the trans is fine and the problem is in the clutch.
Let me know what you find and what trans you have.
