360 transmission whine

No.

See if the transmission is full of antifreeze.

you will have to open up the trany

 

As above, not motor mounts.

You could take the oil filler plug out of the transmission on the rear passenger side of the tranny. Remove the air filter box if you have to get to it. You should be able to determine the quality of the oil in it.

 

If it looks like this when you drain the gearbox, you've found the problem.

Start by looking in the coolant tank. There will usually be oil there as well.

Or check the transmission bushing for wear. I started getting a whine when mine went out.

 

Does the 360 transmission have an integral cooler configuration, with gear lube on one side and glycol on the other side?

 

Yes, #32 in the first drawing. Ferrari has used gearbox coolers since the 355.

They are known to fail.

With the 360 they omitted a coolant change interval from the manual. Coolant becomes corrosive after a few years.

So that’s why I couldn’t see it from the back of the car.

If coolant flush is included with the annual fluids change, this concern should be mitigated. Last year during the timing belt service my water pump was rebuilt. There was no mention of concern with the gear lube cooler that I recall, but worth looking up the service records.

Thanks Tim for the pictures.

 

It's an insidious problem, often only recognized when it's too late. Regular coolant changes might mitigate the chances but after 10-15 years the damage to the heat exchanger is likely done. You could pre-emptively replace the part but it is expensive.

I recommend that both coolant and gearbox lube be changed annually. It's really the only way to stay on top of it and have a chance of catching the problem early.

Many are still not doing that and sticking to the original service schedule.

Its ok. I have been getting a lot of trans rebuilds out of it.

 

Wow
i thought your first comment was a joke
"check to see if you tranny is full of AF"
Now I see that you are not
yuck!

 

So Brian, what is your suggested service interval for this since it is not in the book? Annual? Every other year? When it appears necessary based on a visual?

 

Gear oil and coolant annually. And not all for this reason.

 

gear oil question
I know F cars use shell based lubricants.
I have used Redline No Shock products with great success in the past.
Will be be performing a gear oil change in a few weeks and will use 75W90 NS GL-5 Gear Oil unless I hear it's a bad idea.

Thanks

Craig

 

I sense a friction modifier debate coming on.

 

FYI - That will make up for half of your annual service charges at a dealer.

 

That's what I use.

 

I liked the Redline but it needs some friction modifier in it. I used it without the modifier and got some chatter with tight turns backing up. Taz recommended Valvoline 75w-90 synpower and I LOVE it. Shifts butter smooth and no chatter.

 

Thanks.
You and I are aligned.

Cheers

Craig

 

I drained my trans oil this weekend.
Fortunately it did NOT look like the photo showing green anti-freeze.
Will report back on how it feels with Redline shock-proof instead of Shell 75-90.
Redline DOES smell better.................

Cheers

IIRC you don't necessarily have to see green coolant. If there is only a small pin hole in one of the tubes in the heat exchanger, you may only get a brown milky looking fluid. Did yours look normal?

The guy that owned my car before me did not do a lot of maintenance but he did change the oil, filter and coolant on a regular basis. IS THERE A HISTORY OF THE ORIGINALS GOING BAD?? Is there any DIY info on how to change the gear oil heat exchanger? Other question what kind to replace old one? dynamtechgroup, Daytona sports cars, or a lightweight racing version? I am preemptive, don't like things going wrong when I could have avoided it.

 

Jack I did mine prophylacticly. My service records had lapses, and I wanted to replace the intake manifold gaskets anyway. Once the intake was off it was so accessible I had to do it, very straightforward to replace the exchanger.

I hear there are guys that can replace it with the manifold on, but my old joints may have had trouble with that. Also, I think it would have been a real challenge to get all the plumbing connected without leaks.

I went with OEM, as I read that the manufacturing of the part has improved, and there was no significant cost savings to go aftermarket. Also if you are planning to keep up on on coolant no need to consider other options.

If I had service records that show regular coolant changes, an no suspicion of failure I would not change it, but that's just me. ask the pros.

OE or Daytona only. The other is a dumb design for a street car.

Very easy to replace without taking off the manifold. I cannot imagine taking the manifold off to do it.
