2000 I30 Questions |
|
|
My 2000 I30 has around 70K and runs well except for a couple of things:
1) My car makes a sort of scraping noise on cold starts. Basically,
when I start the car after it was parked overnight, the rpms go up as
usual with normal engine sound. At the end of the start, I hear a
scraping noise for a very short period of time before rpms go down. The
start seems to be OK except for the noise. It only happens on cold
starts and only when it's below 65 degrees outside (It never happens in
the summer). Is that a starter problem?
2) When I brake normally (not hard or anything), I feel a slight
vibration just before the car stops. I don't feel the same vibration if
I shift to neutral before braking. What is that?
3) Again while braking, I sometimes here a noise similar (not exactly
the same) to the one that comes from cold or wet rotors. If I
accelerate a bit from standstill and then brake harder then usual, I
hear that noise as well. Is that rotors? Mine were cut a couple of
thousand miles ago.

The starters are known to dry out and get slow to disengage as they age. It
sounds like that might be your problem. You can take the starter apart and
re-grease it or just replace it. There is a re-greasing procedure posted in
the maxima.org forums.

Probably the transmission's forced downshift to 1 just as the car stops is |
causing the shudder. It shouldn't do it, but it doesn't necessarily signal
any major problems either. Has the transmission fluid ever been changed?

The transmission fluid was changed at a dealer about 7K miles ago. What
do you mean by forced downshift to 1? Shouldn't it down shift to 1 when
you are stopping?

I think he meant it shouldn't shudder on the downshift.

It should downshift as you stop to avoid stalling the engine. I call that a
forced downshift. If the downshift is a little late or the lock up clutches
in the transmission don't release soon enough, the engine can be forced to
too slow a speed and almost stall. Watch the tach when it happens and see
how slow the rpms go as as you are stopping.
Check the fluid level in the transmission. My Pathfinder started doing
something like this once after the transmission fluid was changed. The
symptom was that it only did it when hot. The cause was that it was slightly
overfilled. After draining out the excess fluid (which was only a couple of
ounces), it stopped doing it.

What's the best way to check whether it's overfilled? Also, any way to
drain by myself?

Does overfilling do any damage to the tranny?

Its pretty hard to tell the level on the dipstick if you warm it up
according to the directions in the manual. The easiest way to tell is
probably to check it cold. Start it up, move the shifter through all the
gears, one at a time, ending with "park". Keep the motor running & pull the
transmission dipstick. The fluid should be in the "cold" range on the
stick. Hopefully there is a picture in the owners manual to show you what
to look for. If not, the marks closest to the bottom of the stick are the
cold range.
If the fluid reads above the cold range it is probably overfilled. You will
need to check it hot as well to make sure. Transmission fluid expands as it
gets hot, hence the two ranges on the dipstick. Drive the car for several
miles to get the transmission fluid heated, then check it the same way as
when it was cold and the fluid should be in the "hot" range on the dipstick.
There is a drain on the bottom of the transmission pan, but the fluid will
all run out if you open it. You best bet, if you need to let some out, is a
narrow hose down the dipstick tube and some sort of vacuum pump.

Well, I checked the fluid cold and hot and the level matches the
notches on the dipstick perfectly. What I noticed was that when the
tranny is about to downshift to 1st, rpms would go up a little and then
continue go down. Is that normal? What else should I look at to
troubleshoot this shuddering problem?

Probably the transmission's forced downshift to 1 just as the car
stops is
causing the shudder. It shouldn't do it, but it doesn't necessarily
signal
any major problems either. Has the transmission fluid ever been
changed?
3) Again while braking, I sometimes here a noise similar (not
exactly
the same) to the one that comes from cold or wet rotors. If I
accelerate a bit from standstill and then brake harder then usual,
I
hear that noise as well. Is that rotors? Mine were cut a couple of
thousand miles ago.
