Shift Schedule
Whats the trick to get the shift schedule to match actual vehicle speed. Example - I have my 3-4 shift flat lined at 41 mph and it will shift to over drive around 50 mph.
Ive tried to change the Tire size but it doesn't make any noticeable difference. What ever it is, it is also affecting the Torque converter lock up in the same manner. What did I do wrong

Nothing wrong.
What year is the truck? Is it a SD or OBS?

Yeah, the SD truck stuff is all over the place as far as shifting goes and although it's all relative, the shift points themselves actually don't coincide with actual road speed too well. I love the OBS trucks for that. Usually, everything is within 2 MPH on those.
The SD trucks have anticipated shifting strategies and the like that really mess with what is actually going on.
