Ok so here's the latest:
Got a full TC with Actuator less than 90k miles

First in the hope that it was just the motor, i swapped Actuator only - put on the resistor from my actuator as I read they are matched to TC, then I cleared codes.

Now there is noticeable grinding noise.

I'm wondering since I swapped and cleared the codes the actuator was working again and actuating the clutches hence the noise now. Before I messed with it, I could drive it find with the warming lights on.

Now I have 55C3 limp mode and also 54C4 VTG calibration faulty.

I'm gonna swap the actuator back to the TC I bought and spend 1 more day on swapping the TC. That has to be it I guess at this point.

Thoughts?
