The remanufactured Duramax L5P/L5D Complete Format engine is spin-tested, ensuring proper compression, timing, sensor operation, and oil pressure. “A blacklight inspection with dye-infused oil and coolant is conducted to ensure the engine is free of leaks,” Dooley added.

Solenoid testing is more than checking if a component works—it’s verifying that it performs within specification every time.

Transmission solenoids regulate hydraulic pressure and fluid flow throughout the valve body, controlling functions such as shift timing, shift feel, clutch application, and line pressure.

A solenoid that sticks, leaks, is electrically inconsistent, or responds outside specification can contribute to shift concerns and overall transmission performance issues.

This is why we test every solenoid during the remanufacturing process.

Our testing process helps confirm that each solenoid responds properly and operates within the required specifications before the transmission is installed in the vehicle.

Why does that matter to you - the installer?
- Helps identify potential solenoid issues before installation
- Verifies proper electrical and mechanical operation
- Helps ensure accurate hydraulic control
- Helps reduce the risk of shift-quality concerns caused by faulty solenoids

Every component inside a transmission has a job to do. Testing helps make sure the solenoids are ready to do theirs.

1 company. 2 summer picnics. 2 great times together.

We like to take time each summer to celebrate the JET team and the amazing work everyone does each and every day.

Our Willow Springs facility took in a Springfield Cardinals game, while Southern Indiana manufacturing Associates gathered at Lark Ranch.

We enjoyed getting to spend time with all the Assoicates who came out!

Don’t Let Your Transmission Overheat

In this video, we’re breaking down transmission overheating, what to watch for, and why keeping your transmission at the right temperature matters.

If you suspect your transmission is overheating or having other issues, find a JASPER-certified technician near you to keep your vehicle running strong.
