The complaint

A 2006 Honda Ridgeline equipped with the BJFA Transmission has a complaint of a bind up in reverse and moves forward in neutral after overhaul. The truck would roll freely with the engine off and the transmission in neutral. Since this complaint occurred after overhaul, the technician thought that a clutch was mechanically jammed on due to a mis-assembly issue, but all clutch packs were assembled correctly and clutch hubs rotated freely. At this time the technician made the decision to inspect the valve body.

The cause

The Torque Converter Check Valve and the Lubrication Check Valve located in the main valve body had their locations switched, as seen in figure 1 (above).

The correction

Install the Torque Converter Check Valve and the Lubrication Check Valve in their correct locations in the main valve body as seen in figure 2 (above). Once the transmission was reassembled with the Torque Converter Check Valve and the Lubrication Check Valve in their correct locations, the complaints were no longer present.
