It drives fine but once it gets hot when you change direction the hooter blips and the transmission light flashes, has done it on the odd occasion previously but seems to be doing it more often now!
it has done over 6000 hours.

Personally I'd do it again for the sake of 80 quid

If you never cleaned the suction then probably a good idea to do so but oil and main filter change wont help assuming it had the right oil in it before and there is enough of it.

It might be a faulty presure switch but if not then its a worn oil pump and leaking clutch packs which are taking too long to fill. A presure gauge on it will confirm this as you will see the delay in the build up of pressure.

Does that mean time for a rebuild?

Yes if it is low on pressure its overhaul the box time. Like i said maybe check the suction filter although if its blocked the box is worn out anyway! and a pressure gauge check will confirm what its actually doing and or if you need to replace the pressure switch which would be the simple cheap fix.
