APPS Noise Isolator Dodge 5.9L 1994-2004 / 8.0L 1999-2003

Relatively easy install. Truck now drives and shifts great! No more jerky torque converter lock/unlock. Used to always happen with light throttle when shifting from 3-4 around 45-55mph. Now it’s nice and happy. Thanks for this!

Simple and fixed the problem thank you B.D.

Easy to install

My transmission would intermittently disengage/engage repeatedly at certain rpm ranges. Problem solved! Thanks BD for a REAL and economical fix!

Easy and no problem. Saw it on u tube.

Part showed up within a few days..

The TLDR is this product will fix your gear hunt issues 100%.
First off I did not like the idea of this as many of us 2G Cummins owners the same, BUT after years of chasing this wiring gremlin, the failed effort of replacing the ground wire and running it far away from the wiring harness. Then wrapping the crossover ground wire in foil, replacing 3 or 4 alternators, and in the mean time buying a $6500 trans and converter. Years of sifting through old forum threads and failed attempt after another, I finally decided I was done avoiding this piece because I stubbornly considered it a band aid and I knew I could sort the issue out the correct way. Well I was wrong, as I've already stated I've done everything all of us have done trying to solve this issue. As of today 3/28/24 I installed this and immediately 3 things occurred,
1; TCC on-off switching or "gear hunting" immediately gone, and this is including the 50 mph shift into OD and the immediate unlock then lock, all of it GONE. It shifts into OD and unlocks simultaneously, until about 60 (I have 3.54 gear) where TC locks and STAYS locked. Same as when I shut OD for in town.
2; I've notice lately that my truck feels lazy off the line, takes forever to build boost, very smokey and no tune change. GONE, truck feels peppy again, I believe that the noise in my wiring was causing SO much interference that my ECU wasn't able to moderate the voltage output to the pump. Causing the thing to just run like crap.
3; My engine is quieter, this goes along with #2, I went and sat in a drive thru which is where I always notice how loud it is. Engine is less clattery, combustion noise is down at all RPM and especially idle. I have .0085x8 VCO injectors 100hp over.
Conclusion; this works and it works well. I don't know if if my truck has ever felt this happy and I've owned it since 2019 @ 62k miles and it now has 107k.

Fantastic the part helped the problem of the interference with the hesitation
