Great business to work with they did my transmission in my 07 Cummins A few months back I’ve had time to put some miles down with the new Transmission works great. They are very personable will answer any questions you have my have. I highly recommend

Karl and his team did an excellent job building a stage 3 5r110 for my 06 F350. Having them build it was the best decision yet for the truck. It puts down about 650hp and it hold it so damn well now. They got the truck done when they said they would (5 days) and we’re very good communicating along the way. When I picked it up the truck was clean inside and the professionalism was outstanding. I like working on my own stuff and stay away from most shops, but I will give these guys business any day! 11/10

I had redline build a transmission for my 2005 dodge 3500 3 years ago. I tow my dump trailer with the truck about 150 days a year and havent had any issues in 3 years. I just recently went back and had the trans fluid changed as well as my front and rear differential s. I was able to wait while the service was performed, it took less than 2 hours and I waited in the lounge watching TV. Dealing with redline is so easy I wish all business s would treat you the way they do. I highly recommend them!!!!

I’m from Utah paid in full for a stage 2 48re Karl had it built and shipped in a very decent timely manner! He’s very professional and answers all the questions I’ve had! It’s been a very positive experience especially since this is my first transmission I’ve bought! Would definitely recommend!!

Great place. Very knowledgeable about diesels on Dodge RAM trucks.

The transmission went out in my 2016 Ram 2500, I knew I needed a good one because I tow a lot... i was referred to redline by quite a few guys and after the 1st call and speaking to Karl, I knew I got a great shop.Karl explained the different options and was very professional, yet still talked to me like I was a friend. I also had some turbo issues with the truck and they straightened it out without hesitation.Redline gets a 10/10 in my book. I put just over 1000 miles on the new transmission in 2 days after it being built and the truck runs phenomenal!I highly recommend Karl and his crew at redline!

I’m very happy I used these guys, they fixed up my transmission and added some other stuff to my truck. I would definitely use these guys again.

Great service. They know how to fix a trans right the first time.

Extremely knowledgeable. Very pleased and impressed with their work.

Excellent service. Always make themselves available to answer questions. The amount of knowledge is amazing! Have already recommended them to many and will continue to do so.

These guys do amazing work very reasonable prices youre not going to find any better of a deal for the craftsmanship of the work you get these guys do a very unique and one-of-a-kind job highly recommended to anyone and everyone I would not trust anyone else with my truck I drive 3 hours just for their service

Christina was extremely helpful, worked my truck right in so I wasnt with out it for very long. Great people, will have more work done there on my truck.

Karl and his crew do great work. They put the customer first. Ive been going here for 8 plus years and have had great success!

4 stars because they do a good job but their stage 2 transmission is only a single disc torque converter.

Love this tasty food,my favorite place for food!

Karl and his guys worked in my f650 with a 5,9 Cummins in it for me they are a top notch bunch did a great job there was a over charge when my wife paid the bill and when we went to pick it up there was a check for the difference it the truck already did not have to ask for it it was there its great to find good people when you work on the road like we do go see Karl for anything diesel you have P.S. please see the lady from Louisiana there shes pronlay why Karl does so good. Thanks Again Will

Took my 97 ram 3500 in to have them look at my transmission after paying another shop 5,000 plus to build me a built transmission. hoping it would just be the valve body that they messed up, turned out it was ALOT more than that. decided to just have Karl build me one of his legendary stage 3 transmissions that a few of my other buddies have in there diesels. and i gotta say i have had this in my truck now for a few weeks now and i couldnt be happier with it, it launches off the line now. Karl wasnt kidding when he told me the transmission would boss the rest of the truck around, i had to turn up my idle a tad to keep my truck from idling so low! i was about to give up on this truck after being screwed over but now i couldnt have more confidence in my truck and cant wait to go back soon to get my turbo upgrade! the place really is a one stop shop for ANYTHING you need on top of being extremely nice people also. i remember first time i had work done, it was to advance timing on my 12v. after getting there after a 12 hour graveyard shift Christina handed me a remote and said watch what you like or feel free to take a nap they honestly make you feel like you have been friends for years, so to me it is a no brainer that i wont go anywhere else to have work done on my truck, great people, very affordable prices and a ton of cool trucks to look at what else do you need!!

Best shop around do great service and do the job rit the first time so I dont have to do it my self

Repaired my truck fast and well

Nice shop, friendly staff. Very knowledgeable about diesels

Don’t recommend. Bad experience for such an expensive tranny. There 600hp 68rfe Transmission went out 2 times in a 490hp truck at the tires. the truck has 35” tires. When it finally went out the second time was told they weren’t interested in working on thier Transmission that we bought from them. Do not recommend. Buy a Revv max or bd diesel tranny from a reputable company because we ended up ordering a revmax transmission after this one blew apart for the second time and they told me they wouldn’t work on there Transmission.

Great customer service and theyre ALWAYS right!!!!!

Outstanding service and quality craftsmanship.

Excellent service!!!
