I was an engineer. What I found was that some law schools wanted a high GPA no matter what; other schools weigh the LSAT more and were more willing to overlook a low GPA.
At least at my alma mater, in my major, the question wasn’t a 3.6 in engineering versus a 3.8 somewhere else; it was more like a 3.2 or a 3.0 versus a 3.8. I think our median GPA was somewhere in the mid/high 2 range.
Law school admissions officers aren’t former engineers who understand that a 2.9 is actually a very solid GPA.
