It absolutely solved all my shifting issues. Love the fact that it has a beefy GM solenoid, not sure why they never made them strong like these from factory.Amazing quality, very very happy!

Bought this and paired with BD diesels transducer, if you’re having any shift issues buy the pair and do it once , ATF +4 isn’t cheap!

Fixed a issue where the truck would go in and out of 2nd gear at slow speeds. Super easy to replace. Just drop the pan, 4 bolts, 2 plugs, and you need to move one piece over from the old part to the new part. And then put it back together

48re was starting out in second gear. no other issues. Took me about 1/2 hour to drain fluid, drop pan and replace original with conversion kit, also repaced transducer at same time. Transmision works perfect now!

Definitely better than the dodge ones, I would go threw the dodge ones every 6 months it seemed like after I upgraded and built up my transmission, After I switched to this, no more problems. Anyone with a dodge truck should buy this. Easy install. I regret not converting this sooner.

My truck has trouble shifting from 1st to 2nd and the overdrive struggles to kick in, I also had to do it Manually and slow down to get it to kick in. With this change, it now works perfectly and the shifting are smoother than ever. Thanks 😍

48re on my 2007 5.9 cummins was not down shifting to first gear when arriving to a stop, code P1756 came up (bad psi reading 15-20psi) this product fixed my tranny shifting problem. Highly recommend that Ats product! Also installed a transducer from bd diesel. A must for your 48re trans

I was hoping that this upgrade would eliminate the 1-2 shutter shift under light load but it didn't. The transmission shifts smoothly through all the gears but there wasn't a significant change from the upgraded solenoid I had already installed years ago.

I have a 2004 Dodge Ram 2500 with the 48RE transmission. I should note that I do a fair amount of fifth wheel RV towing. It was shutter shifting between first and second gear regardless if I was towing or not. This ATS conversion kit, along with a BD Diesel Pressure Transducer, fixed the problem. I have driven over 2,000 miles since doing the conversion and my transmission is shifting like new again. The conversion is plug and play with basic tools.Update April 2022: 60,000 miles later I thought I was have the same symptoms again. Turns out it was actually my transmission’s intermediate band being way out of adjustment. Crawled under the vehicle in the driveway, performed the adjustment, and the transmission is shift perfectly again. Check your band adjustment if you develop a shifting problem after you have already installed the ATS conversion.
