Combustion

CLS 550. I am replacing the radiator and of course have lost trans fluid from the cooler lines. Radiator is now replaced and next step is to correct the transmission fluid levels (722.9 I believe. WDD219.372 engine). I have purchased the dipstick to check the levels, but there is no filler tube!!. I can only assume someone pulled it loose when trying to remove the red cap on the tube. What to do?. Any suggestions?

did you ever think that your model may not have a dip stick and of course require special filling equipment------therefore off to any dealer
