Well i know this sounds very stupid but my 84 300d had a lot of rust and like mud in the cooling system, i made a concoction that i was to remove after a brief drive, it consisted of and please dont laugh shout and bleach, the car just started slipping and not going into gear all of a sudden. Mixture has now been removed.I did drive it a couple of days with the soapy bleach mixture to try and cleanse my system but my trans does not feel well at all.
Any help would be appreciated.:confused:

The only component that links the transmission to the cooling system is the transmission cooler lines, which deliver transmission hot fluid to the radiator for cooling, and back to the transmission.

I would look at the radiator to see if the coolant is going into the transmission system. Vice versa too, if the ATF is going into the cooling system it would look reddish. It could have potentially been the rust or mud you observed.

first check the tranny oil
 
.

did you check tranny oil level? if it leaks (or mix) anywhere it will be easily
observed.

also if oil is present in coolant,what about coolant in oil?

it is very hard to imagine those two mixed but if true I guess your
tranny would be destroyed in a minutes.

cheers

very common on i.e. 210 models.
The radiator supplier had issues and this killed many trannies.
In case of 123 the tranny oil heat exchanger tubing in the radiator could be leaking from rust.
Once the car is parked the residual pressure in the (engine-) coolant system pushes coolant into the tranny.
At least the friction plates will be damaged.

Just to agree. Has to be the trans cooler in the radiator tank. DON'T drive the car until it's fixed!

HAHAHHAHAAHAHAHHAAAAA I'M LAUGHING MY HEAD OFF... LOL... :D:D:D:D!!!!

Oops, you said not to laugh. Sorry. I'm Mr. Somber now.








Seriously, the only thing I'm laughing at is you telling me not to laugh. Sorry to hear about your troubles -- if you look at the transmission fluid on the dipstick, milky fluid would indicate coolant in the fluid.

Why did you put bleach in the coolant system?

It definitely could be the cooler, and it certainly could allow antifreeze in the trans fluid. If this is the case, change the transmission fluid and filter NOW, and fix the leak of course! Antifreeze or water in ATF can destroy your clutches.

Best of luck with it.

The possibility of that heat exchanger failing makes me want to bypass mine...

This is why I invested the money in a new radiator! Plus the fact the top of mine was slowly separating...

Ya, but w126 603 radiators are nearly $600!

From WHERE!!?? I've had excellent luck with aftermarket rads in a number of cars and they're WAY cheaper. Many of them seem to came from Canada though I can't say on any particular unit.

I used bleach and shout stain lifter in there because i wanted to do a short run and dissolve the muddish gunk in the cooling system, n ot a bright idea at all, i think some little piece of that mud must have gotten dislogged and made it to valve body, anyway i drained the trans and the converter and replaced filter, topped off with SWEPCO hydraulic atf and one entire bottle of lucas stop slip and the trans is sweet as can be again, to be assured i also picked up a used but in good shape radiator that had been running recently on a clean w123 turbo car, with Mercedes coolant, am also replacing water pump as mine was old and the fans were starting to rust and i am also replacing fan and clutch because i feel old clutch wasnt blowing quite as strong and that may have been part of the over heating problem.
