Be aware of the coolant line connectors! I have a 99 GTP and I put a 2000 GTP rebuilt trans in mine and I had to swap the connectors. The 99's were the last year of the threaded cooler lines. The newer trans came with "quick-connect" connectors that have a check ball in the connector. The 99 trans has a check ball in the valve plate while the newer ones had them in the connector to prevent back flow.
