What year of rover? The first two P0102 and P0103 are MAF sensor codes. The MAF sensor has been known to cause erratic transmission shifting when it has gone out, or is going out. The other P1621 is an alarm fault I believe.

yes you are correct about the codes refering to the maf and alarm all i can find about them is
P0102--mass or volume air flow circuit-low input
P0103--mass or volume air flow circuit-high input
P1621--coms with security ecm not happend within expected time
