Default Transmission problem

My car is hard to get it into gear, especially reverse. If i turn the car off then it goes into any gear very easily but if the car is on the total opposite, i know my axles are toast, could that be part of the problem???

I got no help at all in the civic forum. Please help!!!

What cluctch are you running? Do you have enough tranny fluid? Does the clutch pedal have enough pressure?

Likely the clutch is not fully disengaging. Likely you are low on clutch fluid due to the slave cylinder leaking. However you could have an internally failing master cylinder. Also bad/old/dirty/crappy manual transmission fluid (MTF) will cause stiff shifting. Less likely the clutch pressure plate diaphram springs could be bent or fatigued and not taking the full clamping force off of the clutch disc. I would start by checking your clutch fluid level. If it's low, fill it and bleed it and repeat until there's no air in the system. Next I would check the slave cylinder for signs of leaking. If you have that big release fork dust boot cover it will make it a little harder to check, but either way, pull the slave cylinder piston dust boot back some to check for fluid inside it. There is supposed to be a small amount of grease in there, but not a fluid. If no leaks and no low fluid, check the movement of the slave cylinder. If it doesn't seem to be full range then try bleeding the clutch hydraulics and see if it gets better. If still nothing & slave cylinder is moving well, change the MTF. If you still have a problem, then the only thing left is pull the trans off and inspect the clutch. Another thing that could cause this, the pilot bearing, if it's bad and binding can cause the input shaft to stay (partially or fully) engaged with the flywheel and so never actually stops as long as the engine is running (very unlikely). Even if you don't have grinding when trying to change gears, doesn't mean the clutch is working right. You have synchronizers in the trans that speed up & slow down the shafts for shifting and as long as they aren't burnt up or worn out they will make up for a faulty clutch, but they will wear out much faster if they are doing all the work.

Well good you eliminated low clutch fluid as the cause. But run through the rest of the list of checks I posted and if all that checks out there really isn't much left but to pull the trans out and dig deeper. You have to do some investigating, I can only give you things to check & try. The list I gave you is every check a reputable technician would go through to at least eliminate the easy stuff before deeming the transmission bad. If the clutch pedal feels stiff but you can push it to the floor & not until it gets stopped by 3 floor mats bunched up under it (seen it before), then yes the hydraulics are probably fine.
Here's one last quick check. Put the car in 1st, push & hold the clutch pedal down, start the car, if the car starts to move as soon as you start the car- clutch isn't fully disengaging. Now, turn off the car, keep it in 1st, press & hold down the clutch pedal for 3 minutes, while still holding the clutch start the car and keep holding the pedal for another minute- if it starts to move with the pedal still down- hydraulics are leaking. If you haven't been adding fluid & there are no signs of leaks then it's most likely the master cylinder leaking internally.
Question, how far up do you let the pedal before the clutch starts to grab?
Next question, if you double pump the clutch pedal before shifting from neutral into a gear when sitting still does it shift easier?
Lastly, you said your trans fluid was full, but when was the last time you changed it and what fluid did you put in? Honda does have a news article out about old/bad MTF causing difficult/stiff shifting and needs nothing other than a fluid change.
But these are all things you'll have to check and test in order to find the cause.
