Hey guys, I cannot seem to find any info on the lack of PWR/ECO switch on my Gen2.5.

The main issue I have is that my shift points and torque converter lock seem to be happening too early and even on acceleration from a roll, my TC will not unlock and the engine bogs. My Gen2.5 with the 3.5L is much slower than my Gen2 with the 3.0L. I don't think this should be the case.

My Gen2 had the PWR/ECO button that seemed to resolve this issue. So my question is...before I start tearing my interior apart...does anyone know if the wiring is still in place to add the PWR/ECO switch to the Gen2.5? If so, will the TCU even accept this? Are the TCU's the same part# for both trucks?

I'm thinking about having Brokeback grab the TCU and switch from that parts SR if my harness will accept the changes. Thanks for looking.
