On my '89 Bj74 the tranny is making a chirping noise most of the time. Gets a little quieter when I push the clutch in but is still audible. I've also noticed that shifting has also become a little more notchy. Any suggestions of what the cause could be?

pilot bearing or throwout bearing is shot ?
Cannot be the pilotbearing. This bearing is stationary when the clutch is engaged. You can hear a shot pilotbearing when the clutch is disengaged.
Throwout is not very likely as this bearing is stationary as well as long is the clutch is not pressed.
I would start by inspecting the tranny-oil. Look at the magnet of the drain plug. What kind of metal parts do you find there? And what is in the oil? If you find larger particles, say larger than 0.5 of a mm then something is going south.
If you just find a bit of very fine powdery metal stuff, than there is not much going on.
When was your last oil-change (in the tranny)?

Like a high pitched grind but a very very very quiet one?
It's a throwout bearing.

Ahhh, the cricket. Throwout bearing is most likely. Many have lived with the cricket for years.
Notchy shifting? Check your tranmission and t-case fluid levels. Notchy shifting in my BJ74 was from an overfull transmission, as the seal between the tranny and t-case had failed.

I have the same problem on my 87 BJ74. Mine will go away with the slightest depression of the clutch pedal. Was told throwout bearing by a buddy. Gonna live with it for now. keep me posted with what you find, I feel I may be following down the same path soon.
My mustang's transmission made some random chirps once going down the highway.....

It then completely seized 3 miles down the road on a California freeway. Went under the car to find the driveshaft seal was damaged and all the fluid poured out. My dad, a former mechanic, asked me, "What was it like, everyone has always wondered what it feels like when that happens." Imagine going down the highway 55mph and someone throwing a wrench into your engine. The whole things comes to a screaming sickening hault.

So aside from the noise, I can live with it and not harm other components until I need to drop the tranny to have the clutch replaced or the whole tranny rebuilt?
Re-thinking what I posted before I have to agree to other posters who where saying "throwoutbearing". This because the sound is still present when the clutch is pressed.
This excludes the pilot bearing but not the throwoutbearing.
If the sound still persists when the clutch is depressed and the tranny is out of neutral (so 'a' gear is selected) I would say it's the throwout. If the sound stops with the tranny in gear, I would say the tranny could be having a problem.

It'll be fine.
Forget about it unless the grinding really gets to you.
Half the time a brand new throwout bearing will make this noise too.

so as I said my noise stops as soon as any pressure is put on the clutch pedal. so from what i read this ISN'T the throwout? if not than what, pilot?

It's still the throwout, it's just not AS worn yet.

Bumping this thread cause i just dealt with this and saw the comments.
I had tranny chirping or squeaking, whatever.
When the car was in nuetral, or when a gear was engaged and the chirping increased rythm with speed.
Always disappears when i press the cluth in. First place i looked at was the clutch pushrod and that was it. The metal on metal vibrating rubbing on the clutch fork was it. Threw dab of waterproof grease at the contact point. Done, noise gone.

Squeaking or chirping made me panickly think it was a bearing. So if you got that stupid cricket in your tranny, especailly after some wet weather. Take a look at the clutch pushrod. I have a h55F. Not sure about other models. Hope it helps.
