APPS Noise Isolator

Interference in the throttle position sensor circuits (APPS) on Dodge Cummins engines from 1994 to 2005 will create false voltage readings in the APPS

Accelerator Pedal Position Sensor
circuit and cause the lock-up torque converter to rapidly cycle on and off as you drive. This quick and easy fix removes the annoying and potentially harmful RF interference.

    I thought this would be a BS product, but thought I would try it anyway.



    It has dramatically smoothed the auto shifting. Not just in the 45-55 area that I was having the most problems with, but the whole span. Shifts were a little harsh in other gears, but now they are silky smooth. I would highly recommend it.

    Just wanted to drop you a line and tell you that I purchased this APPS Noise Isolator for my 01 Ram. It completely eliminated the problem of the torque convertor locking and unlocking between 40-50 MPH.



    I was dealing with this issue for 25,000 miles, going to transmission shops, installing a new Throttle Position Sensor, and nothing helped until I installed this Noise Isolator.



    Best $30.00 and 15 minutes I ever spent. After the install, no matter what I try to do, I cannot duplicate the problem.



    Thanks again BD Diesel!!!
