Hard shifting

I purchased an 81' (manual 4 speed) a few months back. Ive noticed if i don't drive it for a day or two, when i start it and go to shift into first or any gear, its very hard or next to impossible.
There seems to be a lot of resistance, it improves and goes back to normal as it reaches full operating temperature. It just seems odd because when its cold and driven earlier that day i have no problem getting into gear. Seems to only happen when its not driven for a day+.

Just curious if anyone has any insight on this?! Could it be merely temp related, or a possible mechanical issue?


Thanks

The shifting in my '83 improved dramatically when I switched to synthetic gear oil in the transmission. I also put synthetic in the transfer case. The gear oil I drained out of the differentials was coal black and so thick that it created "peaks" in the drain pan. My point? Change all the gear oil in your drive train--I bet it hasn't been done in a zillion years. Oh yeah, grease your universal joints while you're under there.

OR. Check your shift lever bushing and seat for being broken apart. Just for grins

The previous owner claimed he had just done all the fluids and changed them over to synthetic. Ill verify the level and clarity of the trans fluid though.
Ill have to have a look at this bushing as well!

thanks!
