Good luck.

Yes, you can get admission but in order to get admission in College of Engineering Pune (COEP) direct in 2nd year of B.Tech/BE course, you have to appear in lateral entry examinations like LEET/ECET/JELET after completing your Diploma from any recognised board.
You must have 60% of marks in your Diploma. According to your rank and performance in LEET/ECET/JELET, you will be allotted a seat in a particular college and then you can take admission directly in 2nd year of B.Tech/BE in that college.

Considering you're from general category, for mechanical you have slim chance though you may get some non-core branches.
