I am currently working on tuning the new built 4L70E transmission in our 2007 TBSS... and for the life of me I cannot get HPTuners (build 3.6.26) to properly read the temp sensor inside the unit. The temp sensor remains stuck at 32*F, and there is no DTC. My $10 ELM using Torque Pro works fine and shows normal functionality of the temp sensor.

Getting this working is critical to tuning the FMC properly.

Any thoughts?
