Hi all,

My corolla, a 89 wagon (4WD), has been running fine since purchase, but yesterday I noticed gearbox trouble after driving over some rough terrain. This morning when the car is idling, I cannot select any of the gears, no matter how hard I try and force it! Reverse doesn't go, but just grinds and grinds.

When the engine is off however, the gears can be selected as normal. I'm guessing something was knocked whilst over the rough terrain yesterday, but have little mechanical knowledge to back up my theory!

Any advice on what the problem could be?

Many thanks for any help!
