http://www.universityofcalifornia.edu/infocenter/transfer-admissions-summary indicates that transfer applicants with 3.20-3.59 GPA had these admit rates to various UC campuses for fall 2014:
36% UCSD
61% UCSB
59% UCI
However, engineering majors may be more difficult to gain admission to than the campus averages.
http://info.sjsu.edu/static/admission/impaction.html that fall 2015 transfer applicants to SJSU needed 2.00 GPA for chemical engineering and 3.00 GPA for mechanical engineering. Of course, thresholds may change in future years.
