360 Transmission filter screen location

Ferrari 360 Annual Preventative Maintenance | Aldous Voice

 

When I did mine a few weeks ago I used a small funnel and a hose to get the fluid in. Measure carefully. It stinks.

 

It's practically staring you in the face!

The gearbox filter is on the left hand side of the transmission near the back.

The fill and drain plugs for the gearbox are close by as well.

I just so happen to have the rear bumper off my car too, so I took a couple of pictures for you.

The first photo shows the location of the fill plug (upper left) and filter (lower right).

The second photo shows the drain plug (middle) with the filter (right).

Both plugs and filter are at the end of the gearbox.

Hope that helps!

Be careful when you remove the screen; it's not truly a filter. It's half plastic and it's old and brittle. Remove the bolt and then carefully rotate the screen using a screwdriver. The O ring seals may make it hard for you to remove the screen and rotating the part first will break their grip. GENTLY tease it out of the transmission case. It may come out in two pieces. Search on this forum for additional photographs so you know what it's supposed to look like.

Since it's so time consuming to remove the bumper, many (most?) screens don't get cleaned very often and some not at all. Consider cutting a 35mm hole in the diffuser so that you can extract the filter when you do normal transmission oil changes. The details of that mod are covered on this forum too. I'll leave it to you to do a search.

 

I am assuming that the filler plug can be accessed with only the under tray removed. I'm planning to cut a 2" diameter hole so my indie mechanic can access the screen -- I just need to figure out where to cut it.

Here's how I did mine. The hole need only be 35mm in diameter, an exact fit with the little rubber cap inside the car near your left knee if your car is LHD.

With the bumper in place, take some measurements to roughly locate the center of the transmission/differential pump screen on the external surface of the diffuser. You won't hit it exactly, but as long as you're inside the correct circumference you're OK. I chose a Dremmel tool for the job with an 1/8 inch cutter which looks much like a drill bit because an ordinary drill is too long.

Next stick a probe into the hole and see how far you missed the center. Mark the true center and then offset that mark by about 1/4 inch toward one edge. Draw a 35m circle around that false center using a white paint pen. The reason for the offset will be clear in a moment. A WD40 cap is perfect to use as a template.

Next cut the hole with your Dremmel tool and check to see how it fits your rubber plug. Depending on how you cut, inside or outside the line, the hole may need to be slightly enlarged.

You will notice that the mounting tab makes it impossible to extract the screen through a perfectly centered 35mm hole. That's the reason for the slight offset and even then a prefect hole is a bit too small. Just file a small notch on one side of the hole to accommodate the plastic mounting tab on the screen holder. You will just barely be able to remove the screen. Of course, you must rotate the partially extracted screen so that the mounting tab matches your notch in order to fully withdraw it. This procedure gives you the smallest possible hole.

Or, you can just cut a bigger hole and use a big rubber plug.

I have a 2" (50mm) diameter plug. I just need to take the car to my indie mechanic so we can put it on the lift to pull the under tray off to see where to drill the hole. Going to install the Challenge front grilles at the same time.

Conceivably you should be able to access the gearbox filler plug which includes the dipstick from the top. The potential issue is that the catalytic converter may block access due to the angle and space available.

The OTC 12mm hex bit socket I purchased from Pep Boys barely cleared with my 1/2" ratchet from below but the socket length is really long (2 3/8"). It definitely would not work from above. I bought it because it was made in the USA, but I did not take into consideration the length.

A low profile hex socket probably would allow access from the top. I just bought this one from Snap-on which should do the trick.

Damn that is close to the cat. Great design Ferrari (like the screen location which guarantees it never gets cleaned).

If you remove the air cleaner box via 6-8 10mm nuts, its very very easy to service. That's how I did mine.

If I did that would it be possible to see where the screen is located so I could cut an access hole in the plastic diffuser?
Thanks
Alan

 

The picture above shows the view to the gearbox filler plug from above so it doesn't really show how much space is available. It's a bit more than that picture may suggest.

Here's the view from below with the OTC 12mm hex bit socket.

For reference, I barely can fit the socket with a 1/2" ratchet since it rubs on the catalytic converter. That's why I suggest a low profile hex bit socket like the Snap-on version which I believe is only 1".

From what I have read, it seems most on FChat are using Redline, but any quality fully synthetic gear oil should be fine.

Personally I bought Valvoline Synpower 75W90 from Autozone.

Royal purple is what I use....

 

Harbor freight has a cheapee set that is short...I know, I know but it will work...my Proto set was to long also...

 

Another vote here for Royal Purple.

 

I used Redline 75W-90NS. Works great. Just be careful how much friction modifier they use in it. Too much and your Limited Slip Diff mught not be happy..
