Default Whining gearbox - any remedies?

Hi

I have a 10 year old Ford Escort with 92,000 miles on the clock. It's
served me well but I need to get another 12 months/15,000 miles out of
it before I replace it. Over the last 10,000 miles the gearbox has
started to whine, nothing major but the frequency is particularly
annoying, especially at motorway speeds. Is there any additive that
would make an improvement or have I got to live with it? A friend
suggested "molyslip", anyone tried this?
Thanks
Mark

Worth a try but don't expect too much.

I have the same problem with the gearbox in my wife's Citroen ZX which we
want to keep another year at most.

The box should use EP 75/80 gearbox oil.
As the noise wasn't present on a cold morning when the oil was thicker, I
decided to change the oil to EP 90 and I used Molyslip though I had received
varying comments about it (the worst being it could wreck the quality of the
gearchange.) I decided if it was too bad I would drain the oil and replace
with new 75/80.

I did this two weeks ago and the change is slightly more notchy, but I think
this has more to do with the thicker oil. The whining is much quieter (and
still getting better) and the vibration at 60mph + has gone completely.
Can't say how much is due to Molyslip and how much due to thicker oil.

The whole job cost me less than 15, is dead easy on a ZX, and has been well
worth it.

I would take the gearbox out and try to find why it is whining. If it has
shed a tooth on one of the gear wheels, putting in additives will not do
much good and you run the risk of losing some or all of the gears if things
get worse.

You could try oil. Have you actually _checked_ the levels on the
gearbox oil ? Apologies if you already have, but you'd be a rarity
if you did so.

Molyslip wouldn't hurt and is easy enough to do. It'll help with tooth
wear, but does nothing if the ballraces have started to crumble.

Make sure it's got oil at all. Many of these transmissions have no easy way
of determining the oil level, with the oil not even mentioned on the service
schedule, and can often go months or even years largely dry.

I checked this and managed to get 150ml more oil in before the stuff
started dribbling out the filler hole. Not sufficiently low to cause a
problem I wouldn't imagine. The problem on this model is that there is
no drain plug so I can't easily replace the oil, only top it up. There
is the reverse gear detent plug that looks like it would drain the oil
once removed but I've been advised not to attempt this in case I lose
the spring and ball bearing in the gearbox.

the only real cure is a new gearbox, but at high mileage, thick oil
helps a lot to keep it quite, albeit at a slight power loss.

All I can say is try a well worn transfer box, main box, and 2 diffs in
an uninsulated series 3 landrover equpped with off road tyres at 70mph
for REAL noise :-)

Is it the gearbox or the final drive? Final drives *may* be noisy but go
on for years. Not so gearboxes, IMHO. On a motorway, you'd be in top which
is usually - on a modern car - direct. So the noise would be a bearing
rather than a gear.

I had a 2nd hand Maestro with a gearbox that was stiff as hell to start
with then became excessively loose and a tad noisy after 15 mins driving.

Drained the oil hot and it fell out (literally) like water. Half an hour
in a big jar outside in January and you could turn the jar upside down and
nothing came out.

I replaced it with (I forget the exact brand) a synthetic gearoil with a
low viscosity/temperature variation, and it was impressively improved. The
gearbox had suffered over the years, but it worked perfectly well for
several years afterwards until everything else fell off and I traded it in.

(I did flush the gearbox before refilling as the crap that came out was
full of allsorts).

I might be able to look up the oil if anyones interested, but it wasn't
excessively expensive, just you won't get it in Halfords.

Buy a new g/box sump gasket and remove sump to change oil. Use heavier gear
oil.

From new, the gear oil should be dropped after 2K miles and replaced with
Mobil 1 fully synthetic gear oil. Replace every 2nd service, that is approx
every 2 years in most cars. After approx 25k miles add Slick 50 gearbox
treatment at each g/box oil change. The transmission will remain like new
for nearly all the life of the car.

From new use Mobil 1, or similar, fully synthetic engine oil, and change as
per makers recommendations. The oil can go longer, so it gives you leeway on
service intervals. No one has a service 9K miles on the dot. No need to use
the likes of Slick 50 in the engine if fully synthetic oil is used from new.

Using the above your engine and transmission will remain smooth, and new
sounding and feeling, for all its life. The only noises will be from the
water pump, alternator, power steering pump and a/c compressor and any worn
belts

Slick 50 do an excellent power steering pump fluid. This is proper fluid not
an additive. This is also well worth using after about 50K miles.

Yup. Mobile are the makers of a well regarded premium oil, and adding crap
like Slick 50 or whatever is likely to damage its performance rather than
improve it. If an additive such as this was needed, the maker would
already incorporate it.

And the life of a manual box depends to some extent on how it's driven -
slamming it through the gears will result in worn synchro clutches sooner
rather than later.

Buy a new g/box sump gasket and remove sump to change oil. Use heavier

gear

From new, the gear oil should be dropped after 2K miles and replaced with
Mobil 1 fully synthetic gear oil. Replace every 2nd service, that is

approx
every 2 years in most cars. After approx 25k miles add Slick 50 gearbox
treatment at each g/box oil change. The transmission will remain like new
for nearly all the life of the car.


Snake oil, snake oil.
Next you'll be claiming that 'Cat-O-clean' works.....


From new use Mobil 1, or similar, fully synthetic engine oil, and change

as
per makers recommendations. The oil can go longer, so it gives you leeway

on
service intervals. No one has a service 9K miles on the dot. No need to

use
the likes of Slick 50 in the engine if fully synthetic oil is used from

new.

There is no need to use any additives or oil's other than what the engine
maker specifies, rather than pay extra for 'additives' just change the oil
and filter at half makers recommendations (both in terms of mileage and
age).


Using the above your engine and transmission will remain smooth, and new
sounding and feeling, for all its life. The only noises will be from the
water pump, alternator, power steering pump and a/c compressor and any

worn
belts


Of course it will, it would do so if you put water in the sump, the life of
the engine might be limited but it would still "remain smooth, and new
sounding and feeling, for all its life" !..

It's nothing but classic marketing blurb for snake oil.


Slick 50 do an excellent power steering pump fluid. This is proper fluid

not
an additive. This is also well worth using after about 50K miles.


If it has nothing added why use it instead of what the factory used ?!

Your post sound like an IMM's 'cut and paste' marketing blurb rants....

I'd like to see some proof that this has any advantages at all. While it
may not cost much, IMHO it's just a waste of money and resources.
For it to be of any real benefit - and I dispute this - it would have to
be from when the vehicle is new, and how many keep a new car until it's
worn out?

I ran a car from new up to 110,000 miles and did what I suggested to the
group. A automotive design engineer suggested the Mobil 1 in the g/box and
Slick 50. He said the Slick 50 g/box treatment is worth it as in puts a
slippery film around the metal parts. It mixes fine with the Mobil 1 oil
with no adverse affects. Do a Google and you will find that people who put
this stuff into g/boxes with wet clutches have had clutch slip. The engine
stuff he was not keen on at all.

I sold the car to a relative and suggested carrying on from where I left
off. He has and is now up to around 160,000 miles. The car still sounds
newish, except some belts squeak at bit. His driving is predominantly stop
start around town, short runs.

'An automotive design engineer'. You're not IMM, are you? All lubricants
put a slippery film round parts - it's their purpose in life.

Have you asked Mobile about this? If Slick 50 is so wonderful, why not use
it alone in the 'box?

Perhaps he designed engines and not gearboxes?

I'd suggest he learns about servicing. Belts squeak because they're
slipping. And need replacing or adjusting.

50 gearbox treatment at each g/box oil change. The transmission will
remain like new for nearly all the life of the car.


If this is the case, do Slick supply a warranty?



I ran a car from new up to 110,000 miles and did what I suggested to the
group. A automotive design engineer suggested the Mobil 1 in the g/box and
Slick 50. He said the Slick 50 g/box treatment is worth it as in puts a
slippery film around the metal parts. It mixes fine with the Mobil 1 oil
with no adverse affects. Do a Google and you will find that people who put
this stuff into g/boxes with wet clutches have had clutch slip. The engine
stuff he was not keen on at all.

I sold the car to a relative and suggested carrying on from where I left
off. He has and is now up to around 160,000 miles. The car still sounds
newish, except some belts squeak at bit. His driving is predominantly stop
start around town, short runs.



A few tears ago I had a boss who had a passat that had done 200,000km -
I supoose about 160k miles?

Ordinary oil, changed by the book, and it was fine.

My last car I had from 10k (ex demo) to 140k, serviced on mileage
intervals only, no additives, Castrol Magnatec mineral oil. It wasn't
using any oil (except when the oil pressure switch developed a leak),
original clutch, no wines or other noises from gear box.

I suspect if I hadn't argued with a wall a flipped it over it would
have gone on until the body fell apart, another 50k or more?

Yup. That's all that is needed - but be careful to check if early oil
changes etc are needed if the car has arduous use, like short journeys, or
low annual mileage. The handbook or service book will tell.

My brother's BMW 520 is over 250,000 miles now and still going strong
despite being used for towing a caravan. Oil changes only by the service
indicator.

Depends on how the car is driven and even 200k miles on modern engines
is nothing amazing these days. I'd rather go by the condition of the
oil than stick to manufacturer's recommendations.

Regards additives, I believe most of the stuff on the market is a waste
of space but Slick50 engine oil additive isn't a bad product. I've used
it and noticed engine noise was reduced, especially during start-up,
with no adverse effects. No idea about the gearbox stuff, never used
it.

I replaced it with (I forget the exact brand) a synthetic gearoil with a
low viscosity/temperature variation, and it was impressively improved. The
gearbox had suffered over the years, but it worked perfectly well for
several years afterwards until everything else fell off and I traded it in.


I had a problem with the syncro on second gear graunching when selecting
at over 40mph (changing up or down). Had a chat with the bods who
service it etc, and they said that Shell had developed a gear oil that
was supposed to fix this problem and suggested I give that a try. Went
for a quick gearbox oil change, and it was like a miracle fix - it
restored perfect operation immediately and it has remained that way for
the last 65k miles. It was IIRC, "Shell Gear Oil S". It was about 10
quid a litre mind you!

Way back in 1990 I had a Vauxhall Calibra 2l 16v. In the four years I owned
it, it clocked up 155,000 miles with no special treatment, just serviced
every 9,000 miles according to the service book. No fancy oils or additives
either. The clutch needed attention at 120k, and the shocks went at 140k but
the gearbox and engine were both fine.

Cheers
Clive

A thicker oil will often help with noise during start up. But a thicker
oil will also increase fuel consumption and possibly warm up wear.

It is true that cars can go long mileages without any major work. My point
was that using Mobil 1 in the engine and g/box and Slick 50 g/box, and the
change intervals I suggested, the engine and transmission is still as smooth
as a new one, even after 100K miles. I have come across cars that have
really clocked up the miles with the usual roughness after 70K. The original
post was about roughness. I suggested how to maintain longevity and
smoothness, which actually does work. My design engineer friends says that
modern engines are designed to be smooth to 50K miles with normal servicing
and decent oil, and some engines deteriorate rapidly in smoothness after
that figure. He recommends fully synthetic oils.

I can't comment on Slick 50 engine treatment as I have never used it. As I
looked after the engines and transmissions from new using the best oils
available, I have never experienced roughness to say that something added
stops it.

On a cold start a thick oil may disguise some noise in a clapped out
engine but not when warm. IME the engines were smoother hot and cold
and there were no negatives regards performance. Also, the oil was no
thicker having added Slick50.
I've used in at least 5 cars - all ex-fleet 2/3 years old with 70k plus
on the clock.
The most important thing is that people use a decent quality oil and
check it regularly.

REGULAR OIL CHANGES WILL HAVE THE SAME EFFECT, it doesn't matter what the
oil is, as long as it is the correct spec' for the engine.

And I have known vehicles that have gone 150.000 plus miles on nothing more
than the makers recommended oils whilst being changed on or before the
advised service intervals for the vehicles use.

Wonder were IMM is ?....

I'd like to see some proof that this has any advantages at all. While it
may not cost much, IMHO it's just a waste of money and resources.


The point is, you are getting rid of impurities that otherwise have to be
filtered. If the oil still look clean, I will agree that there is little
point, but those cases are rare.

For it to be of any real benefit - and I dispute this - it would have to
be from when the vehicle is new, and how many keep a new car until it's
worn out?


Well, replacing a car just because it's X number of years old is what I call
a waste of money and resources !.. :~)
