It was very simple to wire in the speed sensor, I'll agree with that. However the Frost harness does away with it, they specify that plugging in the harness and doing away with a couple codes and you're up and running.
"This harness is plug and play; no splicing involved. It is extremely easy to install. Besides the physical aspect, it simplifies the PCM side of the swap. There is no segment swap (GenIII) or fancy programming needed (GenIII and IV). Converts any 4L60e, 4L65e, or 4L70e to 4l80e, car or truck, even 97-98 LS1's! For 07-later vehicles with seperate trans controllers, an 80 swap can be particularly difficult with the older style harness. With the removal of a code or two from the TCM, that's all you need to get the ball rolling. It retains cruise control and OEM shift indicators. This cable retains FULL LOCKUP at lockup speeds, even at zero throttle. End the annoying cycling of your converter if you originally did it the other way. Made in the USA! "

Supposed to tune and play with my lock up settings Tuesday. So we will see what we can do. Other than that its driving good. 4th gear is definitely shorter. I lost about 6 mph at 2k rpms but I think the small amount we have played with the tune iv gained some fuel mileage even.

It uses a 60E tune thats why, this thread is about running it the 80E way.

Understood, I've tried both methods. Originally repinned the trans connector and tcm, loaded a C2500 Express van tune, and popped DTC U0073. It was suggested I try the harness, so I repinned back to stock, loaded the factory tune, U0073 is gone, but still stuck in 2nd. Last week I replaced solenoid "A" and "B" in the trans, went to try it and now I'm battling anti theft issues. Good times.
