won't go into gear

I am ashamed to say, I haven't driven my YJ for about 2 weeks .
Today I started it and while trying to put it into reverse all it did was grind, I could put it reverse and start it and back up ok, and then trying to put it into first gear it would not go.
Does anyone have a clue what my problem may be.
This past spring I had a used ax5 installed and last year had new clutch installed.
After having the tranny installed this spring I didn't have a lot of clutch pedel and now it goes to the floor.
Please help!

Have you checked the fluid in the clutch master cylinder yet?

I'm going to say it's either the slave or air in the system from the swap. I'm pretty sure you can bleed it without removing anything but I swapped over to the external slave when I did mine last year.

It ran fine since spring and I wasn't to happy with the clutch pedel but since this was not my DD i didn't worry to much about it. I will search but it there an easy way to bleed w/o disassembly?

In the mean time, you can pump it a few times before you put it in gear. I drove mine like that for two years.

Back to this question,
I filled up master cylinder, Jeep goes into gear, shifts ok from 1-2-3-4, but down shifting it is hard to get into the gears.
stopping and trying to put into reverse it still grinds. I have to shut it off and put it into reverse and then start it up.
Please Help!

Did you bleed the system after you filled it up?

No,
I did not. I took the advice from above and it wasn't mentioned to bleed the system.
I will look for a link on how to do it.
Can it be done by one person?

Internal slave...no

External slave..yes but it's not easy.

Best to have a second person to operate the pedal.

Yes, it's a 2 person job with the internal slave cylinder

On my 89, it's underneath the right side of the jeep (looking forward), and it's this guy sticking out of the back of the bell housing:



My bleeder valve is right above my header, just in front of the skid plate.

Be sure to get a rag in there, that fluid screams out of there!!!!! (don't ask how I know )

Update, had the Clutch blead by my local mechanic, He said he blead the clutch and everything seems fine, he thinks my problem is that I do not drive my jeep enough this time of the year and since the tranny has 90 weight oil in it my problem getting it into reverse is because since I do not drive it enough it doesn't get the oil up to a workable viscosity. What do you guys think? Does this make sense?

I think he is probably right. Drain the 90 weight oil and refill it with 10w30 motor oil. You will be alot happier

Jeep has set all winter, I took it for a ride on Sunday and everything seemed fine, shifted great all 5 forward gears and reverse, today I desided to take it to work.
5th gear ground a tiny bit and when I got to work and tried to put it in reverse it started to grind?
I can shut it off and get it into reverse again.

Any thoughts??
