The only time I'm in low range im holding the shifter in low so it won't shift. I am also going slow so I don't care if the speedometer is off. High range is 1 to 1, so the computer doesn't care.
Yeah you should be good to go since you're using a 2wd trans with both speed sensors. I'm using a 4wd trans from a '00 3/4 ton Sierra mated up to a VSS equipped 32 spline NP241 from a '90 3/4 ton Burb for my swap since it sounded like the easiest way and I was able to find everything I needed locally. Since the OP is using a 4wd trans he'll need to figure something out for the second speed sensor or switch to a 2wd trans like you did.
