I have a Manual Transmission Honda. Before I got the clutch changed, the gears were hard to get into and would sometimes grind and not even get into gears at times. However, after i got my clutch changed, the transmission in much smoother and I presume that the transmission oil was changed too. However, sometimes, it will still be hard to get into gear. But very rarely. Any thoughts?
well unfortunately all that grinding that occurred before probably damaged some of the synchromations inside the transmission which makes it hard to get into gear I would just baby it and not cause more damage

thanks, Scotty!
Its possible but unlikely. It could also be a little low but generally speaking gear oil behaves that way in all applications (getting warmer increases the viscosity thus making shifting easier/smoother). Scotty is right - a synchro has been damaged between gear transitions. The only thing you can do is replace or rebuild the transmission. That being said, I have had a worn synchro in one of my 5-speeds for 40,000 miles and its still going. It does the same thing you're describing - when it warms up the grinding is a little less but its still there. Just take care to be gentle with your shifting between those two gears so you damage it as little as possible over time and you might get some more life out of it.
I got my Honda a long time ago. I replaced the clutch when I bought it. After a few months, gear shifting was not easy (the first and the second). I read an article about this problem. It was recommended to change the gear oil (manual transmission, every 80000 KM or three years). The improvement was gradual, and after a few days, I was pleased with the result. Note: You have to use the original Honda gear oil.
I did the same with my Toyota Corolla and I got the same result. It seems people ignore changing the manual gear oil regularly!
@scottykilmer the gearbox smoothens out when the car heats up after a few mins of driving. Could it be that the transmission oil is incorrect?
