I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

What channels to log for a 6L90E? Concerned bout binding.

Is there a list of channels & graph types to log so I can get to tuning my 6L90E?

I have a built 6L90E by Tim King, billet planetary, and upgraded clutches, and a 3100 PTC converter.

It's fresh build and I'm concerned about binding, and softening some the 1-2 shift, it comes on really harsh under low throttle in auto mode. What would I modify to change this?

I've done the reset, preset, fast adapts and relearn proceedure. it failed the first time, completed the second time.

I'm also curious to see how I would notice binding, I hear these build transmissions can be prone to binding. What do I log for that and what type of graph to a make for it?

Thank you for any input on this.
