**DO I HAVE A 4l60E, 4L65E, or a 4L70E??

• If your original transmission has an internal input speed sensor, 4L65e, 4L70e, 4L75e (beginning in 2006 and later), then use part # WATRA31-18.
• Check your ECU in the red (or green) connector for a red with black stripe wire at pin 22, and a blue with white stripe wire at pin 23 or in the TCM, red with black stripe at pin 3, and blue with white stripe at pin 45. If these wires are not there, then you do not have an internal input speed sensor, so you would need the WATRA30-18
• Check your RPO codes in your glove box for RPO M30 (4L60e) or M32 (4L65e). This may or may not guarantee that you don t have an internal speed sensor.
• Count the pins on your original harness transmission connector:
  • If you have 11 pins, you will need the WATRA30-18;
  • If you have 13 or more pins, then you will need the WATRA31-18

Don't take a chance with cheap wire connectors, that use poor quality (wire, crimps, twisted/bent/unseated terminals) and have conductivity issues that will cause your engine to run poorly and be difficult to diagnose.
