Are you tired of dealing with erratic torque converter lock-up problems and sluggish transmission throttle response on the 1998 ½ thru 2002 5.9L 24 valve Cummins Diesel  (With a 46 or 47RE transmission) Dodge Pick-Ups? Have you had your vehicle worked on at the dealership and/or independent repair shop for these problems and wound up having the computer re-flashed, or have you replaced the alternator, battery, electric fuel pump, etc., (as the Dodge Technical Service Bulletin suggests), or installed various resistors (as suggested by aftermarket sources)? Problem still not fixed? Sound familiar? All of these fixes were and are hit and miss, or temporary at best.

     HAPPI BOX may be the solution to your problem.

     We have developed a true , clean, no voltage drop-out signal to the Dodge Computer. No kidding, ..It Works.

    Think of HAPPI BOX as a Traffic Cop for your Throttle Pedal.

     The Dodge Technical Service Bulletin, dealing with erratic torque converter lock-up problems, tells us to look for Noise (a .02 voltage fluctuation in the Accelerator Position Sensor input wire at the Dodge Computer AKA PCM), locate the source of the Noise, and replace the electrical component(s) causing the Noise.

     Wev'e even seen the Snap-On MT2500 Scanner create this Noise while trying to diagnose these and other transmission complaints.

     Once the HAPPI BOX is installed, the electrical component(s) can make all the Noise they want to . It doesnt matter - the Noise is just gone. If you are an Independent Shop, think of how much time and money you (as well as your Customers) will save by installing a HAPPI BOX.

Even if you don't have the problems listed above. The improvements in transmission throttle response and shift timing alone are worth installing the HAPPI BOX. So have fun with  your truck order one today!
