Interference in the throttle position sensor circuits (APPS) on Dodge Cummins engines from '94-'04 will create false voltage readings in the APPS/TPS circuit and cause the lock-up torque converter to rapidly cycle on and off as you drive.

This part is a quick and easy fix that removes the RF interference.

I bought this part as a preventative add-on. After I ended up installing it, I noticed my O.D. seemed to stay in fourth gear longer and not drop to 3rd as much.

Fast shipping

Works great right out of the box. Checked it with a multimeter, and it was set properly from the factory. Thanks!

My truck would shift out of OD in a specific rpm and would actually drop out into a lower gear and then shift back up all in the neighborhoodof 1500 RPM almost every time I drove it.After this install I am pleased to say that the problem has been resolved. I even noticed my cruise control operation has become more seamless.Great price for a quick fix or at least a good place to start if you're experiencing the same issue.

Amazing !

I had put on a new TPS maybe 3 months ago and was starting to have issues again getting into lockup. I found out about this little device, slapped it in and now no more problems! Thanks Geno's!
