I chose using a Remco pump on our 2002 RAV4 at a point where it was more economical to buy the pump than it was to replace the vehicle. Plus, we really liked the car, as evidenced by our decision to buy another one years later. The installation is not particularly difficult, and well within the capabilities of any shade tree mechanic that's able to read and follow directions. When we bought the new 2911 RAV4, everything from our 2002 transferred over to it except the base plate. Oh, and the 2002 still serves us nicely as a second car that stays at our NY cottage.
The Remco pump installation includes a dash control unit that mounts in the coach. The controller will warn of various error conditions ranging from an improper hookup to a low pump pressure, minimizing the risk of any transmission damage due to a wiring or pump failure, or even an operator error such as failing to hook up the umbilical cable or failing to turn the pump on.
