94 vs 95 TCC code

I have 94 4l80e hardware and it originally used $oe and I have switched to 95 code using $31. 95 switched to PWM and the 94 code Had an option to use PWM but it was unset. The 95 code doesn't give you that option. So the moral of my post is it is much smoother with the 95 PWM and it also engages with higher throttle setting as I expect the 94 restricted engagement throttle to try and control harshness.

I was under the impression that all 4L80's were PWM? I knew that in '95 that the 4L60 went to PWM. I haven't seen a wiring difference on the '80 like there is on the '60.

So far as I know the early ones were just on off solenoids. Even the ones that have pwn in the code can use straight on off 12 volt. I use that when I manually lock. I do think the later..98 up..couldn't do on off but I have no experience with them.
