Three members of the gang pleaded not guilty and have been remanded in police custody.
The convicts are 25-year-old Simon Mensah and Jones Osei, 20.
They were convicted on their own pleas.
Other members of the syndicate, 23-year-old trader, Dominic Kwame Fosu, Bismark Amofa, 37, and Felix Ayisi, 23, pleaded not guilty and were remanded into police custody.
They were charged with conspiracy, robbery and stealing.
According to the police, some members of the gang, which operates within Accra, Amasaman and Kukasi, engaged a cabbie in a fierce battle at about 11: 40pm on October 23.
The three suspected robbers attempted to snatch a Toyota Echo taxi with registration number GE 4026-15 from a driver at Amasaman Court area.
The Amasaman District Police patrol moved in swiftly and managed to arrest Simon Mensah and Felix Ayisi.
During interrogation, the suspect confessed to the crime, adding they have snatched more than five taxis through the same modus operandi within Amasaman and its environs.
They also mentioned one Kobby in Kumasi, as the receiver of their booty, and one Kito and Amesroe at Madina as accomplices.
Simon Mensah later led the police to Kumasi to identify Bismark Amofa and Jones Osei as other receivers.
They together led the police to retrieve a Nissan Almera and a Toyota Corolla taxis, which have been sprayed into private cars with fake registration number GN 6704-14.
Jones Osei admitted receiving the stolen cars from Simon Mensah but indicated he sold the vehicles in Accra.
The two robbers were arraigned before the court in Amasaman and were convicted on their own pleas to 15 years imprisonment each in hard labour.
However, they are to face two separate robbery charges against them
Others were remanded in police custody after pleading not guilty.
The gang targets usually taxis mostly Toyota Corolla, Nissan micra, Nissan Almera and similar makes.
They would hire the cab from Accra especially the Kwame Nkrumah Circle, to Amasaman or Medie, and on reaching their destination would pull a weapon, machete or any other offensive object to subdue the driver.
After a successful operation, they spray the taxis into private cars and falsify the documents to enable them register them for sale.
So far, the police have retrieved four such cabs from the syndicate in Accra and Kumasi.
Investigations are still underway to get other accomplices arrested.
