After borrowing a snap on scan tool several times and most recently for an incident I am having with a 4L60E rebuild. I am finding myself in the need for a bidirectional scan tool that will command the transmission as well as other options on body modules and so forth right now the two that I am considering are the pc based autoenginuity and the stand alone Zurich ZR pro from Harbor freight do any of you guys have any thoughts on these two or any other suggestions

Thanks Mark
