1997 Seat Alhambra 2.0 Autobox fault ?

I have a Alhambra automatic, the problem is that when you select drive it does not "creep" also it struggles to pull away and then holds first gear too long, when it does find the next gear it is ok. Reverse gear is fine as is top gear. Also I am unable to move gear shift into 3,2or 1 I am only able to select p,r,n and d. Does anyone have any ideas about this fault before I start searching for a replacement box.
