What can you do if the gearshift gets stuck on a 1998 Volvo S40 manual and selecting gears is getting hard as they seem to jam?

Hey Derek==You have clutch problems. Take it to a garage and have it repaired. GoodluckJoe

I regularly have this every 4 yrs or so the transmission selector bushes need renewing cost approx 50 to 70 pounds , classic signs are difficulty selecting the reverse or 5 th gears initially not sure waht happens later as i change the bushes at this stage

-----------------------------------Update 1-11-12----------------------------- Here's what I did.... Grab a can of WD40 and stick the straw in between the button and the casing and give it a few squirts... Wipe up with a paper towel and work the button a few times... Should loosen right up. At least it did for me.
