Cold weather Good Shifting,Warmer shifting gears gets harder
My 1995 S-10 has had the clutch replaced 50,000 miles ago and the clutch doesn't catch until the floor board and when the trucks gets warmer the shifting gets harder and grinds in reverse. Fluid level is normal.I'm thinking replace clutch,throw-out,and slave.Maybe upgrade to Stage 2 clutch???????The truck has 4.3 Vortech TBI

Generally, what causes C-4's and C-6's to be slugish going into gear, is the seals on the servo pistons are getting hard. The servo pistons are what apply pressure on the clutch packs, when the seals get hard the oil can blow past the piston and the clutch won't engage. It's worse when the the trany is cold and usualy gets better as the oil gets warm. You could try some transmission conditioner, the cheep stuff works as good as the high dollar stuff. Don't rev the engine to try to get it to go into gear, the clutch is trying to engage and you will burn the clutch up pack. If the clutches were replaced 3k miles ago why didn't they put seals in it at the same time?
Sounds like something in your shifting cable, or linkage is corroded, or in need of lubrication. I would guess underneath where the weather gets it. See if you can spray some lube on it to get it to ease up. If it does, you are at the right spot.
First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.
Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,
You need to have it checked out by a mechanic as soon as possible, I drive a 2000 cadillac catera and it began to have the same problems about 4 months ago but last month my sport mode button began to blink which means a transmission problem. So when i had it looked at they said my 3rd gear was almost completely burnt out and it cost $2,000 to fix. The cause was a broken piece of the transmission was failing and it had to be completely rebuilt. Good luck!!
sounds like you have air in your hydrolic portion of your clutch system, you need to see if your slave cylnder or your clutch master cylnder is leaking fluid putting air in your system. If the case is that you have just a hard to get in gear such as only 2nd then i would have suspected your secronizer ring being bad. or if all gears seem to be hard cold then you would either have a leaking hydrolic cylnder or the wrong fluid in trans.
