[W126 Coupe] tranny fluid

[Richard Hogarth]

Bellamy, 
That cuts to the chase, good points. 
BTW - Volvos ain't the only cars where old fluid is a make or break
difference.
 
 Now for the religious experience part:
If you drain the torque converter, you are running it dry for many hundreds
of RPMs while it fills up. The torque converter is a pressure pump, not a
suction pump. Until it starts circulating fluid, nothing else gets fluid
circulated and the Converter is running dry. If one were to purchase a new
converter, the warranty would be voided if you don't fill the converter
prior to installation.    
 
 

Size of Converter 
Number of Quarts 
			

13" 
5 
			

12" 
4 
			

11" 
3-1/2 
			

10" 
3 
			

9" 
2-1/2 
			

8" 
2 
			

7" 
2 
			
					
					
					
					
 
 
Also, the recommended service on some newer automatics is to not even drop
the pan on the tranny. Ford recommends that for the first tranny service,
the fluid gets suctioned out through the dipstick tube. It's the second
service where the pan gets dropped and filter screen changed. They don't
drain the torque converter at all.

Oh?  half a bath?  Look at it this way...  how often do you change your
transmission fluid?  If you're only going to change half of the fluid at a
time by not draining the converter (an exaggeration... you're changing
considerably more than half), then change it twice as often, right?  But
ALWAYS change your filter, OK? 
 
Let's not turn changing your transmission fluid into a religious experience.
We have read how to check the oil level every which way short of while
driving at 50mph.  We have even heard that the dirt in your fluid might
actually be the only thing that is holding your transmission together,
('specially if you drive a Volvo).
 
Advice:  Simply follow the Mercedes instructions.  If you don't do it
yourself, take your car to a Mercedes specialist.  

OK?

Steve- I'd say amen to that.  Not draining the converter is like taking a
1/2 bath, or only draining half of your motor oil.
