Volvo A40 not shifting out of 1st gear

I've got a 1998 Volvo A40 that's new to the fleet it's the first adt I've had the privilege to work on
The owner bought it from a auction and it doesn't shift out of first gear I'm waiting on the manual's but just wondering if any of you guys had any ideas
thanks
