To swap a transmission from a Grand Prix GT into a GTP, you will need to:
- Remove the transmission from the GT.
- Install the transmission from the GTP.
- Modify the transmission mount.
- Modify the driveshaft.
- Modify the wiring harness.
The transmission mount will need to be modified to accommodate the different transmission case. The driveshaft will also need to be modified to fit the new transmission. Finally, the wiring harness will need to be modified to connect the new transmission to the car's electrical system.
Once you have made all of the necessary modifications, the transmission from the Grand Prix GT will be installed in your GTP and you will be able to enjoy the benefits of a more robust and powerful transmission.
