https://www.universityofcalifornia.edu/infocenter/transfers-major indicates that UCLA chemical engineering admitted transfers had 25th-75th percentile GPA of 3.85-4.00, with 13% admit rate for the most recent year shown. With a 3.1 GPA, UCR may be more realistic (but probably still a reach or high match). http://www.sjsu.edu/admissions/impaction/impactionresultstransfer/index.html#Chemical indicates that SJSU may be another more realistic school, based on previous year transfer GPA thresholds.
