Command TCC with V2

[l3elivE]

I'm getting my V2 on Monday, and I was wondering if I can command the torque converter for troubleshooting purposes?

[joecar]

Yes you can.

[l3elivE]

Ok, Thank you

[joecar]

I should have asked you this first: which trans do you have...?

[l3elivE]

Allison 1000

Ok, got my EFI live v2, but I can't figure out how to command the torque converter. Does anyone know how to do this?

[joecar]

Start scantool, File->Select Controller (select your flavor of Allison), File->Connect, goto DVT tab, select your Allison controller, click Activate, goto Gear tab, checkmark TCC Solenoid, click Turn On.

Be careful, use common sense.

Is your Allison an AL5 or A40...?

[l3elivE]

A40.
When I connect to the controller though with EFI live 7.5 scan tool, I do not have any supported PID's for transmission. Any idea why?

Do this:
- On the PIDs tab, uncheck Supported;
- File->Select Controller, and select A40 Allison 6 Speed TCM;
- File->Enter VIN, and enter the VIN;
- Info->Validate Pids, and let it complete;

you should now see a bunch of pids.

I'm getting a bunch of PID's now, but not the TCC slip one that I need.

TCCSLIP may or may not be defined for your TCM... was it previously defined that you know of...?

is there a TIS pid that you can compare to the RPM pid (to obtain slip)...?
