I just removed my transmission to replace a slave cylinder and someone was interested how I did it. I am just documenting here how I did it. I am trying to be as safe as possible but you would do it at your own risks.
1- Loosen the front wheel bolts, while the car is on the floor, Don't remove them obviously.
2- remove the drive axle bolts behind the center wheel cap, both front wheels.
3- lift the car on jack stands.
You need to place the stands behind the plate that supports the subframe as the subframe will need to be removed. You will need to raise it high enough to get the transmission to roll out. Mine was raised 46 cm from the floor to bottom of the car. It is better to raise all 4 wheels about the same height to keep the car level.
4- remove both front wheels
5- drain the transmission by removing the 24mm plug at the bottom of the transmission. You will need 2 liters manual transmission oil to refill it. Volvo oil #: 31280771.
6- remove brake pads and then brake calipers and suspend them with some wires to the coil springs. Label the brake pads to put them back in their original position.
To keep track of all bolts and small parts, I put them in zip bags along with a piece of papers explaining where it is coming from and a number to remember in which order I took them out. I must have been using about 40 bags so far.
7- remove the ball joint nut on both sides
you will need a counter hold.
8- disengage the control arm from the ball joint.
I use a chain, steel bar and a block of wood for this.
9- remove passenger side axle. First tap the axle to push it in by about 2cm. Then by pulling gently the axle you should be able to disengage it from the spline. You will also need to remove the half shell holding the mid bearing.
Then pull gently the axle out.
10- remove driver side axle. Could be difficult, but I explained how I did mine in this thread:

11- disconnect the propeller shaft from angle gear.
Mark how they are connected to put them back in the same position later.
I used this as a counter hold:
12- remove the angle gear. The top bolt is not visible but can be removed with a 10 inch wobble extension over the angle gear. The next one down requires an offset wrench:
13- remove the collar sleeve. Mine is now welded to the shaft of the angle gear. If it has never been removed before, it is probably glued to the transmission shaft and will be very difficult to remove. I had to use a 12 ton hydraulic gear puller for mine, but others had some success with simpler setup.
14- on the top of the engine, remove the bar supporting the top engine mount.
15- remove air filter box and intake to it.
16- disconnect MAF and vacuum lines and remove the intake between the turbo and the MAF
17- remove the heat shield over the exhaust manifold.
18- disconnect the down pipe from the turbo and remove it. Before removing it, support the cat back with some boxes on the floor.
19- remove the over the engine pipe from the turbo..
20- drain the cooling system. I am not sure it is absolutely necessary, but I did it as several coolant lines are removed.
One might also drain the engine oil if the turbo is to be removed,
21- remove the turbo. I am not sure it is absolutely necessary but it does give more room to work around there. To remove the turbo:
a- from the top, remove the screws holding the coolant line and the banjo bolt for the oil line.
a- from the bottom, remove the bracket holding both coolant lines to and from the turbo together, the two screws for the lower coolant line, and the banjo bolt for the oil supply.
c- from the bottom also, remove a third banjo bolt on the other end of hard oil line, above the bracket holding the bearing for the passenger drive axle. I had to remove this bracket to see this third banjo bolt.
d- remove the oil line that was held by the third banjo bolt.
e- remove the bolts and nuts holding the turbo to the exhaust manifold
f- remove the turbo from below
For refitting you will need two new gaskets for the coolant lines, 6 new copper crush washers of various sizes for the banjo bolts and one gasket between the turbo and the manifold.
22- remove the shift cables from the top of the transmission.
a- pry the round one on the left with two flat wrenches
b- for the square one on the right pull the pin (not all the way) and pull up the cable.
c- disconnect the connector for the reverse sensor
d- remove the rest of the cables by pushing toward the back the white ring for the left and black ring for the right, and then pulling up the cable out. If you can't push the ring by hand, try prying the ring back with a screw driver. Don't try to pry up the cable before pushing the ring back. I made that mistake.
23- remove the bolt at the top of the rear engine mount, in the back of the engine. If you have not removed the turbo, it would probably be more difficult to see.
I had also disconnected the coolant pipes to the heater core, but I don't think you really need to if you only remove the transmission.
24- clamp the hydraulic clutch line with a hose clamp.
25- disconnect the hydraulic clutch line from the front of the transmission.
There is a small pin you need to pull with a small screw driver before pulling the line up.
Put some plastic film with a rubber band on the input to prevent any dirt from getting in.
26- remove the 3 clamps holding the electric wires to air box brackets
27- remove the left air box bracket by removing the two nuts at the bottom
28- remove the right air box bracket by removing the two bolts in the front and then remove the third bolt in the back to remove the aluminum bracket as well. This will get in the way when removing transmission.
29- remove the grounding cable from the engine
and the subframe.
