Why blend in, when you were built to stand out…

The wait is over. The WP Developments 10L1000 is here.

After the success of our 10R140 program, one thing became clear—there was a serious need for a real 10L1000 solution.

So we went to work.

After thousands of man-hours in development, testing, and failure analysis, we’re proud to officially launch the WP Developments 10L1000 transmission lineup.

This isn’t a thrown-together “performance rebuild.”
This is our proven formula:

✅ Tested hard parts upgrades
✅ Billet valve body options
✅ Converter packages built to match your setup
✅ Refresh components to address common failure points
✅ Built for towing, daily abuse, and serious horsepower

Whether your truck is a heavy tow rig, workhorse, or high-horsepower street build, this platform was designed with the same mindset that made our 10R140 program a success:

Build it stronger. Test it harder. Refine it until it’s right.

100% USA parts. 2-Year Unlimited Mile Warranty. Financing Available.

The strongest 10L1000 on the market?
We’ll let the results speak.
