Recently my 2001 buick lesabre service engine light appear and when shift in gear it jerks, also while driving its doesn't seem to be shifing in gear and the RPM goes between 3 & 4. I took it to Autozone and these three warning codes appear: P1810, P0141, & P0135. Do you think it's something major wrong with the transmission? Help please
