Stiff gears after a while

[juxtapozed]

Hello all,

New to the forums and apologies if this has been asked (couldn't find a topic through search).

At the start of the day, my car is fine to drive but the longer it's driven the more difficult it gets to change gears - especially into 2nd and 3rd. Everything else seems fine.

I've found that if it's revved higher than normal (3-4000rpm) for local driving that the gears get progressively worse quicker.

Hope someone can help as I can imagine the Toyota dealers not sorting something like this out cheaply!!!

Thanks in advance...
