Removing the 30mm transmission output flange/yoke nut correctly.

I am about to remove the 30mm nut from the transmission output flange/yoke on my 1994 Mercedes E320 wagon. I am using a electric impact tool while under the Mercedes undercarriage body. Before I do this, I want to make sure what direction correctly to remove the nut. Is the removing the nut going clockwise or counterclockwise? Comments, advice/feedback is greatly appreciated.

More than two people said counterclockwise.

I got the 30mm nut removed from inside the transmission rear case housing using the 30mm deep well impact socket using the impact power tool. It took 2 seconds. After removing the nut, the output flange came loose and the remaining rod shifter bent inside came out easy.

I then removed all of the 9 bolts from the transmission rear case housing. Drippings of transmission fluid came out. I got the housing loose but not enough to pull it out completely. I tried to pry with a screwdriver, but no luck. Is there some kind of gear pulley type tool to put on the housing in order to remove it? Any ideas, thoughts, comments, feedback, advice is greatly appreciated.

If the tripod yoke is out, and all bolts are out - and the gasket has let go, it will come out like any other tail extension housing. It has to clear all the way till where the tripod is, dont try to tilt it as there is a bearing inside.

I finally got the rear transmission case housing removed. The reason for the case housing would not move is because there is a 3/4 inch bolt on the right side facing me that needed to be remove. Sure enough the case housing came loose with a little prodding. See pictures below:

Glad to see you won the struggle. What caused the old one to break?

Zulfiqar, I believed you are correct after looking images of that particular item. I was not sure what it was until you mentioned it. It looks like it.

Sugar Bear, thanks for posting. Good to hear from you. I am not sure what you mean by what cause to break. If you are referring how I was abled to get the transmission rear case housing after removing all 9 bolts and still stuck, it is because of the kickback solenoid with the 3/4 bolt in the way. So I removed it as shown in the pictures and was abled to freely removed the housing.

While I was researching on these issues, I came across this interesting website that is quite almost the same thing I went through. Check it out, very interesting reading:

The cause of the problems was due to flex discs failures.

Sugar Bear, after reviewing your post in regards to what caused the old one to break. If you are referring as to why I had the rear transmission case housing to replaced is because the old case was missing the transmission mount hole at the bottom of the rear transmission case housing. So I assumed you are asking what caused to break? It was because of the chain reaction of flex discs failures that caused a series of damaging parts that I had to replaced. I found this website that practically explains it all. It is Failure of the Flex Disc on a 12. Sugar Bear, I hope I answered your question correctly.
