Hey there,
I'm half was through reading your two year old post:

Awesome. I'm hoping to get to a part where you figure out the thud/stutter from 1st - 2nd gear... from stopped. That is my issue and I'm hoping it's just a solenoid. regardless, your post is a good read. Would love to ask you some further questions if you are down? thanks - Josh
