WP Developments 

At WP Developments, we don’t just build automatic transmissions — we redefine what they’re capable of.
From street to strip to the pulling track, everything we do is tested, proven, and built to take a beating.

We’re known for setting records with the 48RE and 68RFE platforms, and we back it all up with real-world results from race trucks, work rigs, and everything in between. No stock builds. No fluff. Just hardcore R&D, innovation, and power you can trust.

Subscribe for behind-the-scenes builds, brutal test sessions, transmission tech, and the raw side of diesel performance.
