You will need a swivel as well as several extensions and sockets. 10mm, 13mm, 15mm, 17mm wrenches and sockets. It will be required that you drop the exhaust too.

Hopefully, the car will be high enough so that you can lay under it.

It is not easy to drop a tranny from a 320i.

take your time and work carefully.

Couple of points to be aware of:

1: make sure you take the flywheel cover off the trans bellhousing (between the bellhousing and the steering rack) BEFORE trying to remove the trans - trans won't come out if you forget.

2. make sure you disconnect the flex hose from the slave cylinder on the firewall AND unclip it and pull it down under the car before removing the trans - there's lots of places for the hooked end of the hose to catch on in the engine compartment.

3. Personally, I think it's easiest to remove the circlips on the shift linkage and remove the shift lever before dropping the trans - makes the job MUCH easier (just dont lose the linkage clips and washers)

Other than that, it's just a matter of disconnecting the driveshaft at the quibo, pulling the engine to trans bolts, and unbolting the crossmember - rear of the trans will drop down far enough to slide out easily when the crossmember is disconnected.

All you need are two 17mm wrenches, an open end 11mm wrench, one 10mm wrench, one 9mm, one 12mm, one 13mm and one 14mm wrench. Other than that a 3/8" drive ratchet with a regular 17mm, 14mm, and 13mm sockets. One #2 Philips, one ¼” flat screwdriver, and some sort of cheater bar. Don't forget a hand truck or wheelbarrow, half dozen or so latex gloves, half a roll of paper towels and some waterless hand cleaner.

All you need to do is…..

First remove ALL bolts around the bell housing, start at the top and get every one you can reach. There are 10 bolts total that you need to remove around the bell housing….

2 bolts (17mm head) on the starter, 2 more bolts with (17mm head) on the bell housing, 4 smaller bolts (13 or 14mm head, I don't remember which) on the bell housing, and finally two (10mm head) bolts that hold on the sheet metal flywheel guard.

Next go inside the car and remove the shift knob (the shifter will just slide through the hole when you remove the transmission), make sure the e-brake is off and that the transmission is in neutral.

Find a clean mat to lie on, trunk liners and such make a great work mat.

Go under the car and remove whatever bell housing bolts you couldn’t reach from the top.

Now grab your two 17mm wrenches and remove the guibo bolts, sometimes they are very tight and you may need some sort of cheater bar.

Now slide on down to the center driveshaft support bearing, there probably will be a heat shield that you will have to remove to get to it. Remove the 2 bolts that hold up the center bearing. Pull the driveshaft towards the ground and you should be able to slip it out of the transmission.

Now grab your 11mm wrench and remove the clutch line from the slave cylinder.

Also pull the reverse light harness off, there is a connector up by the shifter.

Now the last step is to make sure you have a clear landing spot and to carefully remove the bolts that hold up the transmission cross member, now you should be able to tilt it back and pull it away from the engine. It is pretty light, but make sure you are in a safe work position, because if it falls on your face, your dentist will be a rich man.

That’s it!

I forgot to say that it is necessary to remove the heater hoses, heater valve, air cleaner, and a little relay that is on the firewall to get to the starter bolts. That should not take long at all, and if you do not care about the heater hoses a knife makes quick work of them.

The only other thing you may run into is that the catalytic converter may be in your way, but most wrecking yards remove the catalytic converter before the car is put out to pasture.
