So, I was taking a look at this here:

JET Performance 70701 - JET Shift Commands - Overview - SummitRacing.com

And wondering if there was something similar for the 4t65e-HD.

If not could this device be jury-rigged to work with the 4t65e?

I mean, I can't imagine that the signals it sends would be too much different.

(This is probably a stupid question, I know. You don't have to tell me that.)
