I bought a 2017 ram 2500 that recently had a built transmisson through this company. The transmisson was purchased 14 months prior amd costed 10,200. Long story short input shaft broke the first estimate was 8,029 and that was to fix my transmisson with no warrnty. I agreed to give the 8000 with a warranty but he wouldnt.Then after i said i wuldnt pay 8g with no warranty he did offer to sell me one for 6g with no warranty. I told him no thanks i wanted a warranty that i could buy one from auto zone for for 3500 amd it came with a 2 year warranty. That this one went out in 14 months and i didnt ant to be in the same boat later.
One thing about the company that they do that i dont like is they sell you used parts but dont want to warranty them so if one of the used parts they sell you brake your screwed. So i decided not to get mine rebuilt through this comapny and took it else where. Thought about buying a new one and putting in but they wanted to keep my old one and charge me an addiotional 2000 dollar charge 1500 for another core and 500 to break it apart. Which made the total 10,800 more then the first one. When i asked why i wasnt charged the core to fix my transmisson when they quoted 8029 but charged my old transmission and a core on a new one i never received a message back.

I couldn’t be happier with my experience at **Redline Diesel Power in Medina, Ohio**. They recently built the 68RFE transmission for my 2020 Ram 2500, and the results are nothing short of amazing. The truck runs incredibly smooth now—better than it ever has.
Rachel and Karl were fantastic to work with. They were prompt, professional, and patient with every question I had throughout the process. The turnaround time was impressively quick, and the quality of work speaks for itself.
If you’re looking for knowledgeable, trustworthy diesel experts who deliver top-tier workmanship, I highly recommend Redline Diesel Power. I’m extremely satisfied and will definitely be back for any future upgrades or service!

Redline absolutely took care of me just like family, because we are. I live in Alabama and my racecar hauling truck needed some attention. I coordinated with them what I needed, payed online, build was completed and shipped to me in very reasonable amount of time, I sent code back in a week for them, installed the unit myself with the excellent detailed instructions and awesome warranty instructions also that helped me figure out what I didn’t even know to be an issue with my Cummins TPS. Anyhow the unit works great has a good warranty and I’m thoroughly satisfied. I give Redline a 5 of 5 star rating thanks yall!

I contacted redline about my 68RFE transmission. I wanted to do a valve body and a few other small modifications without the cost of doing a full build just yet. I have no doubt they will do a full build for me someday. Great communicators honest people and you can tell they are true masters of their craft! After completion of the valve body thermal bypass and deep pan along with service, the truck is shifting firmer and trans is running significantly cooler.

I was recommended the 700 68rfe. And this is the smoothest shifting built trans i have felt. Super fast turnaround, too. If you're kinda far like I am, don't worry. They are super helpful with options and ideas on how to get your truck back to you quickly.

Had my 16 68rfe rebuilt here. Nothing but good things to say. They’re priced right. Got the truck back and a solenoid went out within a week gave them a call and they did not try beating me up about it they got it back in as soon as they can and made the repair for the defective part. It’s been 8 months and about 10,000 miles and it’s running super strong with no issues. Highly recommend.

I have had a very very excellent experience with redline, I asked quite a lot of questions via email, and they would respond within a few minutes every time, very nice and professional people, they know what they are talking about and make a very nice quality product. I purchased a built 47RE transmission for my ram pickup and it has been driving beautifully so far, amazing customer service, great product, and a pleasure to work with. Definitely recommend
Update : I have put about 700 miles on the transmission and it has been performing beautifully so far, very nice quality product

Have had Redline Transmission in my truck currently for about 1200 miles. Transmission is very solid and you can defiantly feel the transmission holding onto the gears longer while in use. Another big plus they had my truck in and out in 5 days. This was great because my truck is my daily driver and tow rig. Got to keep the miles off the wife car. 100% recommend this company. Can't wait to tow the fifth wheel this summer.

Had a transmission built for my 2015 ram 3500. Everything about my experience with them has been awesome. I’m very happy with everything and would recommend anyone to them.
