Only interested in Transmission temp. Oil pressure and transfer temp. So unless I'm reading your reply wrong it can be done. If so can you send me a file to apply to my Trinity 2? Heat is what destroys these 4T65-HD transmissions. I have a cooler but would love to keep a eye on it.

Try this PID
PID: 221940
EQUATION: A-40

And see if that gives you transmission temp in Celsius.
I just find it odd that a handheld scanner will give me that information.
It's built into the same model Pontiac GXP's info center.
And with a OBDII Bluetooth device and a Android program it can be done ...

A 2008 Pontiac GXP had a onboard info center that included transmission temperature. I guess that was through a temp sensor unable to be read by the ECM? Just curious. Actually all the LS4 GXPs had that.

Can you only customize or create your own guage layout when the Trinity is actually hooked to the car? Or can it be done hooked to a computer?

I realize that. I already have a Intune i1000. Although the Diablo website does state that the MX is Upgradeable. And yet it appears to be false. That should be changed.

Just bought a 2008 Impala SS 37500 miles. 5.3 LS4 V8 I've add the 93 octane tune with hard shift. I can feel a substantial difference. Used Intune i1000.

I recently purchased a Trinity 2MX for my 2008 Impala SS. I had hoped to monitor oil pressure and transmission temperature. I'm having some difficulty figuring out exactly what it will monitor on my model car. Can you give me a idea of what it can and cannot monitor? Or link me to something that ...
