Description
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.

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!
Solved 100% of my lockup problems

I have a new, not rebuilt transmission (47RE) and have had problems constantly with the torque converter going in and out of lockup to the point the truck almost wasn't driveable. The transmission shop replaced a solenoid under warranty but it didn't solve the problem. I decided to try one of these isolators. My husband is a Cummins tech and it took him less than 10 minutes to install. I have driven 200 miles at this point, including pulling a trailer and I now have ZERO issues with it dropping in and out of lockup. Wish I had done this a year ago. It's like having a new truck!
