Bingo.

To be completely safe and sure of your diagnosis (or mine if you prefer to
pin it on me), you should go ahead and check that the trans fluid is full. I
suspect it is, but even if it isn't, it generally contributes to grinding
between gears more than prohibitting selecting 1st.

Pumping the pedals and having that bring them back into service means the MC
is toast.

Second that, Jeff. Just changed mine out for that very reason. After
swapping the mc out I looked at the insides and it was full of 'mud'
from deteriorating rubber somewhere so I swapped the slave as well.
This one was tricky: pump it up and it held for several minutes -
maybe an hour. Next time, it would bleed down so fast I had to time
it to get it in first. The piston was fine - it was the mud getting
into the valve at the end that lets in more fluid when you pump it up.
Once pumped, I rarely saw any bleed off while the clutch was in, so
it didn't act like a common mc failure.

If the brake fluid in the system is cruddy, you probably found the
problem and cause.

Advice: if you change the mc, change the slave as well (it's the
external one). The dealr only sells the 2 as a unit with the line
already attached but you can save several bucks by shopping one of the
after market parts houses - Advanced Auto and Pep Boys had it for next
day delivery. Swapping it out is simple.

Got to chuckle at this. As I said earlier, mine was not bleeding down
while pressure was on so much as when off it or if I pressed slowly.
I was doing a bunch of pumping - until the !@#$%^ offset arrm that the
XJ/MJ uses on the clutch pedal broke off. Now THAT is what I classify
as catastrophic - good thing I had a strong battery and was only 10
miles or so from the barn.
