Problem Description

Long story short ...im trying to find the short in my electrical system and my transmission is good and so is my computer however there is a short somewhere so my car keeps going into limp mode and really need a scanner that can clear trans codes so i can still use car during the loooonnnnggg process of figuring out which wire is causing the short....so my question is would a launch crp 123 be able to work for my needs?
