Transmission help...
So, my transmission has two problems. It is stuck in overdrive and won't come out. and the hydraulic line is squirting fluid out around the coupling when I hit the clutch pedal. It is a Mazda M50D 5-speed. I have replaced the little snap ring in the slave cylinder and the o-ring on the coupling. I think it has something to do with the new snap ring, but what do you guys think? And as for it being stuck in overdrive, I think it just might be under a lot of pressure and the engine needs to be started to relieve that pressure, or thats what grandpa said anyways. Thanks for the help.

There's a white colored plastic bushing/collar at the hose input of the slave cylinder. When that bushing is pressed all the way in towards the trans. it releases some metal springy fingers that keep the plastic hydraulic hose from pulling out.
When you reinstall the plastic hydraulic line make sure you pull the bushing back towards you. It takes a lot of force to push the line back in so the metal fingers lock it back in place.
If you replaced the O'ring and you're sure the hose is locked in place and it leaks, you must of damaged the metal springy fingers. If you have an old slave cylinder, you can swap the fitting from one to the other. The fitting is held in by a roll pin. Problem is, you need to pull the transmission to get to the roll pin.
As for the transmission stuck in 5th gear, you didn't mention how that happened. 5th gear and reverse gear share the same shifter fork.
If the shifter was sloppy, could be the plastic shifter bushings are cracked or the pivot pins the shifter pivots on are worn out.
Only way to tell is remove the 3 torx screws and pull the shifter lever out of the trans. Look at the black plastic bushing that will stay attached to the shifter and the other black plastic bushing held in place by the two pivot pins that are pressed into the top shifter cover of the transmission. Look for cracked bushings or worn pivot pins.
Here's a link explaining how to replace the shifter bushings.

Well, can you just take the ring out of an old slave cylinder instead of replacing the fitting and avoid pulling the tranny?
And as for fifth gear, the bushings are good, those were replaced last year. Tha tranny did fall off of the jack during a clutch job and I turned the output shaft to turn the input shaft to align the teeth. Those are the only two thing I can think of that would cause any problem. Does that help give you a clue?

Here's a picture of the slave.
I've circled in red, the roll pin that holds the hose fitting in place. I don't see any way to replace that fitting unless you pull the trans and remove the clutch slave.
So before you reinstalled the transmission all of the gears shifted fine?
If that's the case, you said you turned the output shaft which turned the input shaft to align the shaft with the clutch disc. This indicates the transmission was not in neutral. If you reinstall the shifter and the transmission is not in neutral it can cause the problem you are having.
If you remove the shifter stub and look at the shifter cover when the transmission is in neutral the shape is like a rectangle where the shifter stub is installed.
