My clutch/trans loves the cold.....it shifts smooth on all 4 gears

when I drive for about 30 minutes...the gears tend to be harder to engage...

disc gone?

I am doing a clutch job soon but wanted to get your opinions......

Car was in a field or barn full of goats,mice,vermin for a few years...and forgot to ask the seller about the clutch....I strongly suspect it's time for a clutch job....but was curious as to why it started to slip at the half way point of the temp gauge.....

there might be a little visible oil on the pressure plate but does not look new...and I will replace the back crank seal etc at the same time I do the clutch job...
