Not surprised. Most people dont. Its either called a glasses screwdriver or a jewelers screwdriver. It does not matter as long as it is a object small enough to fit in the hole.

This is a great write up. I was having issues with my TCC locking up way to soon, super close and soft shifts.

Mind you my FI is controlled by Holley but my trans was being controlled by my OBD1. I think the trans was kind of confused.

I installed A USShift transmission controller and was able to adjust my TCC lock up, shift points and Firmness.

So if you ever want to fine tune your Trans thats an option.

Is that with the 4L60E or 80?

Its a 60. An 80 is in the making. Exact controller but different harness will be used. The shift software will need to be changed too, but thats done with the click of a button

Got the prom adapter, burned the only 5.7 4l80e file that was called out as such on the $0e file library on gearheadefi.com

Works well!
