The Mercedes Benz auto which was used from 2002 to current 997s even is another story entirely.

Suggestion
One of the problems you will run into is being able to secure the torque converter to the transmission as there is not enough room between the transmission and the body to insert the factory tool for this.
Use bell housing adapter plate between the engine and trans

Suggestion
The MB trans uses a bell housing adapter plate between the engine and trans which makes separating the trans with the motor still in the car practically impossible.”

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys,
I have been doing some research on removal of the gearbox from the car. It is a 2002 996.2 C4 with the later MB tiptronic. What I have gathered is that the MB gearbox cannot be removed with the engine attached to the car - both must come out together. Why is that, and does anyone have any experience with this gear box?
This is from some very knowledgeable gents on another forum.
“...correct on this one. The ZF which was installed from 99 to 01 is readily removable from the car without removing the engine. The Mercedes Benz auto which was used from 2002 to current 997s even is another story entirely. The ZF trans bolts directly to the engine case. The MB trans uses a bell housing adapter plate between the engine and trans which makes separating the trans with the motor still in the car practically impossible.”
“Practically.
One of the problems you will run into is being able to secure the torque converter to the transmission as there is not enough room between the transmission and the body to insert the factory tool for this. So the torque converter will probably come out just enough to dump all of its ATF all over. The main problems with this are... ATF is #1 messy and #2 costly and #3 kind of a pain for a shadetree mechanic to top off correctly (you'll need a
durametric
at the least). Also getting to the screws which hold the transmission to the bell housing adapter is what is going to be silly. Get all of your wobble, universals and extensions ready because there is absolutely no room, even with the engine lowered. I know several technicians that have tried this once and sweared never to do it again.”
Since I've just been through an engine transplant, I can say that there's really no good way to drop the MB trannie on it's own.
IF you were to try tho:
Remove the starter - that's if you can even see it...
Then rotate the crank until you can see the bolts that attach the flywheel to the torque converter - there's three sets of two at 120 degrees to each other. Make sure you don't drop a bolt 'cos there's absolutely no way to get to it and it will foul the flywheel...
Best to drop them both as a unit...
This is a source reference. Confirm exact model applicability in the original material.
