**DO I HAVE A 4l60e, or a 4L65e, or a 4L70e??

The 4L75e is not a production transmission and was only available through a GM parts distributor
If your original transmission has an internal input speed sensor, 4L65e, 4L70e, 4L75e (beginning in 2006 through 2008), the WATRA31-18 is required.
Check your ECU in the red (or green connector) for a Red-Black Stripe wire at pin 22, and a blue-white stripe wire at pin 23**or**
In the TCM, Red-Black Stripe at pin 3, and Blue-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.

ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.

STEEL (steel bolts): Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steels as well.
