01 TJ tranny grind
 

Ever since that evil drunk dude hit me in my jeep, I occasionally have a
somewhat grinding noise putting my jeep into 1st gear from a dead stop...

For instance, I will come off a freeway and stop at a light... jeep in
neutral. Then I push in the clutch, move the shifter to 1st and thats when
I hear gear grinding. The sound occurs before I release the clutch, and
keeping my foot on the clutch moving the shifter back to neutral and then
back to 1st it doesn't make the noise again. I get it once in while after
stops, but it happens every time I drive it. What's going on? Could the
tranny be pushed over or something? I was hit on the left, pushed 10 feet,
smacked to a dead stop on my right via a big curb.

Any ideas?

Hi Troy,
Check and make sure your clutch reservoir is full of brake fluid.

When you shift into N and let the clutch out, the Input Shaft spins away at
whatever the idle speed is, but the other gears are stationary. You need to
depress the clutch earlier so the stuff slows down before you pick your
gear, or shift into a higher gear first so the speed of the Input Shaft more
closely matches the capability of the synch rings to mesh, then shift into
1st.

Synch rings are not unlimited in their ability to deal with mis-matched
speeds, and the speed of the Input Shaft and the stationary 1st Gear shaft
are greater than the synch rings can deal with. The only recovery from this
is more time, OR selecting a gear that is not suitable for starting out then
reselecting the appropriate gear to start out.

Try watching the light for the cross traffic, and preparing (depress the
clutch) for you gear selection when the light turns yellow, then actually
make the selection when the light turns green for you. The delay between
depressing the clutch and picking your gear will stop the grind ...
