Hello!

I am new to the forums. I've got a 2003 Ford Ranger XLT Supercab. I got it at 54k miles. Now I am at 69k and the the gears seem to be much harder to shift into. The 3rd gear has always been a bit notchy, but now I really need to push it into gear. Clutch never slips at all, never grinds. Just tough to push it into gear. Any suggestions as to what I should do? I have been looking around to learn how to replace the transmission fluid and possibly the slave cylinder? I am no mechanic, I've just searched online. Any advice anyone can give me would be great! Thank you!
