How hot is too hot - Transmission
 

Hello Group:

I read someone on this Forum discussing they needed to take breaks on track day because their transmission oil gets too hot.

I have the stock transmission oil gauge with temperature markings in Fahrenheit but no red markings on the gauge to let me know when hot is too hot.

At what transmission temp do I need to back it off, and let it cool down?

Thanks

That's the engine oil temp. Limp mode kicks in around 260.

If you have the manual. What happens is the clutch fluid boils in the clutch line next to the left side exhaust pipe. And you lose the clutch pedal. The fix is to wrap that clutch line with insulation. ;)

Transmission doesn't have a temperature gauge...

Therefore... it's fine.

:p

I should have mentioned I have the manual transmission.

So the round gauge on top of the dash is engine oil temp.

What are the little dots below the fuel dots? Water temp?

The person discussing transmission oil temp must have put in an aftermarket gauge. Do I have to worry about transmission oil on a manual? I know nothing about transmissions.

Also heard on this thread that if my engine oil gets too hot the car automatically goes into limp mode. Is that correct?

Sounds like the only heat issues I need to deal with on the track or brake fade and clutch heat.

You're going to need an oil cooler for track use, or spirited street driving. Or simply for commuting in warmer climates.

You're correct, the dots are water temp.

I thought you might have a manual.

The dots are water temp.

No, you don't have to worry about tranny temps on a manual. Just insulate the clutch line like I said in an earlier post.

The Z will go into limp mode if the engine oil gets too hot. The ECU will start to pull timing first. I believe it starts at 240deg, and increases as the oil gets hotter. At 260deg, the ECU will go into limp mode. Not allowing rpm's over 2,500 I believe.

If you are planning to do trackdays. 34 row oil cooler. Bleed your brakes with good brake fluid. Something like Motul 600. Insulate your clutch line. And read this thread.

The better you get and the faster you go the more you will have to deal with heat soak and over heating. You will need to change your fluids more as well. I change my oil after each track weekend or no more than two track session between oil changes. Brake and clutch depends on various signs and symptoms.

Ain't too many people cranking out 900hp like yours!

Lol, 240* to 260* oil temps and boiling brake fluid happen on 150hp brz's! Mine just just get there faster and the is why I have a big cooler and lots of ventilation.
