Your truck isn't a toy. It earns a living.

Whether you're towing every day, hauling equipment, or putting serious miles on your pickup, the last thing you need is another "rebuilt" transmission that's loaded with the same factory weak points.

At WP Developments, we don't just rebuild transmissions—we engineer solutions.

✅ In-house valve body upgrades that address common factory failures
✅ Billet converters built for towing and heavy loads
✅ Proven packages from 400HP to 1000HP+ depending on platform (More power means stronger parts for towing and abuse)
✅ 2-Year Unlimited Mile Warranty
✅ Financing Available

From the proven 68RFE to the 6R140 and the rapidly growing 10R140 platform, every transmission is built with one goal:

Get you back to work—and keep you there.

Because when your truck pays the bills, "good enough" isn't good enough.

The 10R140 builds never stop around here.

2 years ago, we changed the 68RFE platform and launched WP into what it is today. Green Handle Media

It's been a busy week with 10R140 phone calls.

We're seeing it all... 2026 trucks coming straight off the lot with valve body issues, older trucks dealing with CDF drum failures, and plenty of owners frustrated with problems that shouldn't be happening.

The good news? A 10R140 with a WP valve body is a completely different animal.

We don't just sell these parts—we develop and beat on them. Our in-house test truck has spent months towing heavy, climbing mountains, daily driving, and taking everything we've thrown at it. That's how we validate our products before they ever reach a customer.

And here's the best part: if you purchase one of our 10R140 valve bodies today and decide to step up to one of our complete transmissions later, we'll credit 100% of your valve body purchase toward the transmission.

Fix the weak link now. Upgrade later when you're ready. No money wasted.

That's the WP way.
