If you tranny is hunting this is the fix.
Issue fixed, but not permanent

Bought this for my truck in hopes that it would fix the shifting issues, which it did, but it didn't hold. There are lots of weak grounds on the PCM and I cleaned and wire brushed them all. Worked for a couple weeks then trans went out completely. Replaced it with a suncoast omega alto to the tune of 5k. This will help if you are running lower power levels but, start throwing big injectorz, aggresive tuning and more boost at it and the stock trans will die. Super easy install though. Recommend relocating both PCM grounds to cleaner location with more surface area.
Can't believe it

Transmission shifts like it should, no overdrive dropping in and out and no more issues with the APPS!
Amazing product!! Very Pleased and highly recommend it

had the TC lock up issue with my 2001 cummins where it would cycle on and off rapidly once cruising speed was established, 65-80km/h, the rpm gauge would spike about 100-200rpm and you would feel a slight pull/slip in the trans, didn't happen all the time but happened fairly frequently, this product instantly fixed this issue and so far no problems, install time was like 10 minutes if that by myself and the most time consuming part was taking your intake off... enough said haha overall very happy with this product and i highly recommend it, especially for how cheap the fix is compared to other routes you may take. two words are easy and affordable, great fix

Experienced the typical cycling between 40 and 50 with my auto trans. Cleaned grounds and terminals but it came back. Finally installed this, shifts like brand new. Installation takes 20 minutes at most - fixed ALL shifting problems. Can't recommend highly enough - will save you time and money fixing a simple known problem

Stopped the lock and unlock of the torque converter between 40 and 50 mph and also got rid of the problem of my transmission kicking into neutral before downshifting going around sharp corners
No more goofy shifting.

Great upgrade for the price! Install is easy as can be. I recommend this to anybody with an auto trans.
Worth the money!!!!!!

Must do this first.

If your having the lock unlock issues at 45mph or the wierd or irractic shifting. Do this first before you start pulling sensors and replace everything. I pulled the pan changed the fluid installed new sensors you know the gov pressure and shift solenoid that everyone says to replace. Still the same issue. Bought this and installed in 5 minutes and problem solved. Yeah it doesnt look like much but the truck shifts like brand new again.

My trans would jump in and out at slow speeds 1-2 gear bought the truck used did same thing took it back under warranty dealer rebuilt trans was ok for a while then did it again left it like that for a while then saw the bd isolator said what the hell 21 bucks can't hurt got it on and this thing Is like a new truck shifts smooth now. Like everybody else said best 20 buck I spent thanks Jeff for the info on it and xdp for the great service.
Best $20 I ever spent. Thought my TC was going out.

I've been getting the common lock/un-lock symptoms with my trans for a couple months now. I though the tranny was starting too slip. Best and easiest fix I have ever installed on my 98.5 cummins. Big thanks to XDP and BD. I will recomend this site and product to all my buddies with Dodge's.

Ordered this up from Jeff, after I had been dealing with my TC locking and unlocking while cruising at 45-55mph...figured it was worth a shot for $20 before I start looking deeper into the problem. Best $20 I have ever spent! Took me about two minutes to install. Also did a fluid & filter change, and a band adjustment on my 47RE, and my trans shifts like a dream, and the TC doesnt lock and unlock while cruising. BD makes a great product, I've installed a few other electronic products BD offers on a couple other trucks, and they're very simple, and work great. Thanks XDP!!

I had been fighting the feeling of shifting in and out of OD (between 45 and 55mph) on and off for a year or better. The dealer worked on this and claimed weak batteries the first visit and a new battery cable and a $600 bill. It helped but the problem came back. The 2rd dealer visit they wanted to replace the Trans. A Transmission shop reccomended cleaning and tightening all grounds. Again this helped but still happened. This APPS Noise Isolator was the cheapest next thing to try. It was very easy to install and it stopped the problem!
