4T65E Ratio and Application Chart The 4T65E utilizes several different final drive and drive to driven sprocket combinations. Installing the wrong transmission, drive/driven sprockets or final drive can result in several different ratio error or slip DTC’s . If a ratio error or maximum adapt DTC is present, and the unit has been previously repaired or replaced, final drive ratio and/or drive and driven sprocket ratio could possibly be incorrect for your application. Refer to the chart to determine what final drive and sprockets should be used for the application. As with other GM vehicles the engine, transmission and final drive ratio information for your specific vehicle model is located on the RPO. The RPO label should be used exclusively to determine which transmission fits in which vehicle body style and application.
