noisy tranny

I've got a 2001 Civic with 135k, manual transmission. Don't know if had
the MT fluid changed ever. For about 2 days started to make a grinding
noise when engine is revved up, typicaly in 1st, 2nd and 3rd gear.
Any ideas what could be wrong?

Thanks.

 

sounds like the front bearing on the input shaft. needs a strip-down.
you'll damage it if you keep driving like that.

The second sentence probably answers the fourth. Is this describing
Change it with Honda MTF and see what happens. Google will help with the
procedure, or www.tegger.com

Check all the TSB's at tegger too.

Another thing to think about: When they bled your brakes, did they bleed
the clutch fluid as well, and are you having any trouble getting it into
reverse?

Don't know about the clutch fluid.
Actually I can never get into reverse in one move - have to try 2 or 3
times, while the tranny keeps grinding gears.
Thank you.

That's an important clue. Let's go one step farther - if you hold the clutch
all the way down and gently try to shift into reverse, does the gearbox
silently resist shifting in, does it grind but the grinding slows steadily,
or does it grind and the rate doesn't change?

If either of the first two, the problem is in the gearbox. The obvious first
step is to have the gear lube changed with genuine Honda MTL (there have
been good reports using Redline MTL, but I've never tried it). If the third
one, the clutch is dragging.

-----------------------------------------

If the tranny is not allowing you to get into REVERSE easily, but you
can get it into the forward gears (because they have synchro), your
clutch is probably dragging. You need to bleed the brake fluid in the
clutch hydraulic system. It's a thirty minute job for a you and a
flunky. There is air (and likely lots of moisture) in the clutch
hydraulics.

Can you easily get into reverse with the engine OFF?
