I have the same problem, shifting from 1st to 2nd from a cold car is occasionally difficult. I just take my time shifting and manage to get it to go without abnormal pressure. After the car warms up, the problem goes away. I will probably change the transmission fluid to one of these soon to see if it makes any difference:

Note that the manual specifies a 75W-90 gear oils with grade GL-3. From what I can find, GL-3 has been mostly superseded by the GL-4 specification. In any case, excellent synthetic GL-3 oil does not seem to be very available. My research also suggested that GL-5 gear oil would not be appropriate for this transmission.
