Just finally got to drive with my new 4l80e! But I don't know if this is right or if something is wrong.. Drives ok, But my gear shifter no longer go down to 1st. It showing second in the place of 1st.. Is this normal for a 4l80e?

No you need to adjust your shift cable....or the nss! If its going mechanically into first and showing 2nd on the dash its the nss... If it only going to 2nd its the cable

park and reverse and D seem right.. How do I check the NSS, neutral safety switch? (Also I have to do a segment swap.)
I will do that as soon as Hptuners get back to me.
