DNJ has done it again!
Since its release, the 10L1000 has struggled with persistent valve body issues. Premature wear in the pressure regulator (PR) bore often led to uncontrolled line pressure — in many cases even resulting in cracked castings.
In addition, wear in both feed limit bores has caused shifting concerns, momentary wheel lockup, and trouble code P0747.
But finally — there’s a fix. DNJ to the rescue.
Introducing the DNJ 10L1000 Billet Upper Valve Body — engineered to eliminate these common failure points and deliver the durability and performance the industry has been waiting for.
Huge thanks to DNJ Components for continuing to innovate and for their commitment to helping transmission shops succeed.
