Is this a genuine original part?

This is a premium quality 4Drive aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for heavy-duty performance.

How do I know if it is compatible?

We recommend checking the SKU/MPN and Cross Reference list provided above. This solenoid is specifically for the Delco MT series (10MT, 20MT, etc.). If your original part number matches any of these, it is a guaranteed fit.

Why does my original have 3 terminals and this has 4?

This unit includes an 'R' terminal (Ignition Bypass). If your original application only used 3 terminals, you can simply leave the 'R' terminal unconnected; the solenoid will function perfectly as a 3-terminal unit.
