[R129 SL] problems automatic gear.

[Jan Kuylaars]

Eva,
 
Thanks for advice, I fill today the gearbox with one liter transmission
oil. 
At first I had hope the problem should be solved, because by switching
true the gears the bad noise disappears in the drive stand for a while.
But after switching several times true the park- drive and neutral the
noise come up again.
Checking the fluid level lets see that the oil is foaming.
Now I leave the car for an hour and hope that there is air in the system
that must come out.
After that I will try to drive some hundred meters to see what happens.
If it don't change I must put the car back in the garage, leaving for a
day and test it again.
 
BUT I AM AFFRAID THAT I DROVE THE CAR TO LONG WITH TO LESS OIL AND THE
GEARBOXPUMP IS DAMAGED.
 
WHY? AS LONG AS I HAVE THE CAR ( BOUGHT BY THE DEALER ) THE FLUID LEVEL
WAS NORMAL TO THE MAX , WITH COLD ENGINE.
 
NOW I READ IN THE DVD THAT THE MAX WITH COLD ENGINE WITH MY GEARBOX
722353 SHOULD BE 10 MM UNDER THE MINUS !!!!!
 
So I drove 40 000 km with overfilled gearbox, and I think that's the
reason the oil  is foaming with extensive heat as result.
The heat properly damaged the seals so its going to leak with to less
oil as result.
 
So I had a lot of trouble with this car, and now the gearbox should be
replaced for an used one.
And the engine also has the problem with the leaking valve rubbers and
with a pill repaired head gasket cooling leakage problem.
What should I do? The car is old but beautifull. It looks like new. For
the rest everything is working.
I bought a other house and don't have the money now to buy a other car,
and with damaged gearbox no dealer is willing to pay a reasonable price
for it.
 
Maybe make a deal with the company that uses wracked R129 cars to
replace the engine with the gearbox together for an younger version he
has.
Or simply let the gearbox revised, or change by used one about the same
age? Or revise the gearbox and the engine?
Maybe I could buy an other car for that costs.
 
I don't know.
 
Jan.

HI Jan,

 

It sounds like a problem I had a year ago, same symptoms.  I had to tow
my car to the garage.  The car would not accelerate and had a hard
start. The mechanic tried cleaning the injectors first but that did not
work. He charged me $$200.00 USD for the labor of cleaning the
injectors.  The symptoms re-appeared a couple of days later.  This time
he decided to replace the distributor rotors and the distributor cap.
He also found a damaged pin for distributor.  He managed to fix the pin
but not replace it because it's labor intensive. I paid $380.00 USD for
the parts and $0 for labor.  

 

Later I found the parts on the internet for less the half the price.
The baby has been working excellent since the replacement of the parts.
He also replaced the ignition switch.  I paid $81.00 for the part and no
labor cost.

 

Hope this helps

 

Eva

Hello folks.

 

Today the sun was shining and having my car left alone for more then
three weeks I decided to make a drive.

Halfway my ASR lamp comes on and my gas pedal want react as it should.

I stopped because I had the gas problem some weeks ago; the cable came
out the handle.

 

But today that was not happening. 

My engine makes a strange noise like bearings were dry.

I  checked the oil and there was enough, the oil from the automatic gear
was lower than normal , but I could not see exact.

 

I drove to a gas station, filled the engine with 1 liter oil for sure,
checked and it was just under the top limit.

 

Then I drove at home, hearing the noise up en down depending on the
engine speed.

Whit 60km/hour the noise was low.

The engine temperature was high; around the 100 degrees Celsius.

I wait 30 minutes before I drove farther. The temperature was lowered to
80 degrees Celsius.

I saw some smoke coming out under the car  and again I wait for 30
minutes to cool down.

Then I had to drive 5 km and at the last I put out the motor and set the
gear in neutral.

The last 100 meters I drove the car normal and find that the gear was
shifting raw.

 

Leaving the car on the lane to my home to cool down, I discovered that
the oil from the gearbox only was on the top of the dipstick.

After two ours I could see that there was gearbox oil dripped on the
lane.

I drove my car into the garage and the engine? gearbox makes a raw
noise.

 

So with to low oil maybe normal.

Now I will fill up tomorrow the gearbox with oil and hope that the noise
is gone. 

Off course I must repair the leakage.

 

 I was confused ;should a leave the car on the road or drive at home.
Because we can not tow the car , I decided to drive home in steps.

Totally it was 10 miles.

 

Has someone experience with this? Is my gearbox gone to heaven and must
I replace the complete box?

Or is there a change it will survive?
