You're absolutely right. Works a charm now.
I had missed the general GPIO build part. Oops.

Re: Upshift pressed always on. 4L80E
Lance,
I didn't populate VR2 as I don't use the up and downshift buttons (yet). Even if I pull the respective jumper, PT6 VR2 in this case, the situation stays the same. I've measured between PT6 and ground to check for a ground path and no, infinitive.

I had tried to hook up RPM's but didn't work and I figured that as long as there is an input speed sensor this would not be n...

4L80E PC always 100 percent
Hi, I've built and installed MShift on a 4L80E and after a few hiccups everything's working. Using an MS-2 for now but will be switching to non-Can when everything's sorted out. Already using ISS as tach input. Just 2 issues that need sorting out: 1. VSS drops to zero every now and then, always at a...
