So the neighbour has a Yaris which she's had from new. It's about a 1999 car. 1 litre and she only does 1000 miles a year in it. Today she started it after not driving it for a month. Then without going anywhere in it she turned it off again. Then she couldn't start it as the gearbox was stuck in first.

I've been round and took the change cables off the gearbox to make sure they were free and the gearbox arms just dont move, either of them. Is this gearbox definitely seized?

Also got her to press the clutch pedal and the slave cylinder moves in and out.
