No - for tranny it's just an external replacement & $8 part.

Ok, I removed the skid plates under the car and I don't think it's motor oil. THE Drain plug, bone dry, the level sensors bone dry, valve cover gaskets, bone dry......
So now I'll tell you what I saw.... NOT GOOD. I found the entire transmission pan saturated with oil, I'm assuming transmission fluid, could still be motor oil but I'm assuming tranny fluid. So, I cleaned everything down, engine cleaner, garden hose, made it shine. Will monitor but any suggestions? Again, no motor oil area is leaking, transmission yes.
2 other questions?
Where can I buy a transmission dipstick to check the fluid and add when needed? I will need to remove a plastic lock cover off of the dipstick pole for checking the fluid level, then install the dipstick.
What kind of transmission fluid can I use? Thanks Guys!!!

OK - Check the electrohydraulic bush - see link above.
Check pan gasket & plug crush washer.
Check front & rear seals for leaks.
Check that this banjo union is tight. It can make a real mess.
Use fluid meeting 236.14. Shell ATF134 is the cheapest from Ryderfleetproducts - search link on the forum.

I bought my 722.6 tranny dip stick from KTC Auto Tools , ElMonte CA for $20 + postage. Item # 260860304996. You can buy the plastic locked cover pin replacement from the dealer for $2.

ok, do you need to buy a new plastic cover everytime you check the fluid level? Can you leave the dipstick in the tube or do you need to remove it when done checking level? Thanks

You just need to buy the red tab. 98 cents. You can't leave the dipstick in. This is not a conventional dip stick. It's long & measures by being bottomed out on a base plate in the tranny.

Yes - but that is a crap price. I paid $8 for my last genuine Merc one from RMeuropean. Let me check.

That's not a proper Benz one but I guess it's OK if properly calibrated.

Just a snippet, I found that the locking tab can be used again after having the red top broken off to access the dip stick tube.

It can be inserted from beneath & locks the cap well as it is an interference fit.

This is useful if you wish to drive the car to bring your ATM oil up to operating temp. then open the tube to top up if needed.

Sorry if I'm being difficult but I am still confused.......
On the transmission fill cap area there is a protective locking cap (black in color) with an area, as shown in the pictures, that can be removed, does that peice need to be broken off and then replaced with the red replacement pin.
http://www.rmeuropean.com/Part-Numbe...b-7cc5f6f71ee3

I guess what I'm asking is, once this piece is removed, is that where the ATF dipstick go into or does the entire black locking cap have to come off? And does this procedure have to occur every time I want to check the ATF? Thanks guys!!

The entire black cap has to come off to measure fluid level. You remove/pull the lock pin from the transmission filler cap, then pull off the filler cap to measure the the fluid level. When you are finished measuring fluid level, replace the transmission filler cap and the new lock pin.

understood, and I will be able to reuse that new lock pin for future checks or is it designed to break every time I need to remove it?

Designed to break. Just keep a few spares lying around.

ok, I understand now.
Another question?
Can I use Castrol Transmission Fluid or do I need to buy M.B. Transmission fluid only? Autozone says it will work but they are not sure......

NO!

You want to use only approved fluid. The best place we have found for that is http://www.ryderfleetproducts.com/ry...oductDetail.do
The dealers charge 3x that price.

Whatis the proper procedure for checking the tranny fluid? Can you shift through the gears while the dipstick isin the tranny tube or must the vehicle be park only?
Thanks
