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

DTC p0141 is indicating a faulty oxygen sensor, an easy and inexpensive repair

DTC p0135 also indicates a fault on the oxygen sensor circuit.

DTC P1810 is a transmission fault code which indicates the transmission fluid pressure manual valve position switch is malfunctioning. Most likely fix for this is just replacing the switch.
