So let me clarify real quick that I DO have TCC lock-up. The thing about it though is I have the Trans-go 2&3 kit setup with the stick only option (Full manual valvebody). The TCC lockup wiring in my valvebody is the type that relies off governor pressure to ground the circuit out and lock the TCC. The stick only option of the transgo kit places a spring clip on the governor, commanding full governor pressure 24/7. Because of this, my TCC would remain constantly locked.

As a remedy, I used 4 SPDT relays to create a latching on/off relay cluster toggled by a momentary push button on my shifter handle. In short, the ground for the TCC lockup relay never makes it back to the ECM, so the ECM has no control over lock-up and I manually lock/unlock the TCC myself.

I am thinking it might be a good idea to disable TCC lock-up altogether in the tune since it would be possible for the EBL to command a lock-up, thinking it is locked when it really isn't?

Also, are there any other options or parameters I should configure for having a manual valvebody? I have verified in the WUD that the EBL is able to differentiate between D (1-2-3) and OD (4th).

 

Just set the enable temperature high (150* C):

TCC - Lock Enable CTS

That will prevent the ECM from commanding the TCC to lock.

Thanks Rob, as always! Slowly getting the hang of this elaborate contraption
