Day 2 (yesterday) Photo of the progress that was made.
Day 3 (Today 10/28) was told that they found an old clay drainage system, so they are going back to the drawing board. All of the area between the road and sidewalk will have to be cut out all the way down past our building. So the 2 week completion date will now be months because they probably wont be back till mid December. A good bonus, he said he will fix the area on the sidewalk between the road and our front door that pools rain water.

Check out the video of David here talking a little about our newest part, DJAK10L1000 10 speed Valve body that we designed and now manufacture all in house here, at DNJ, along with this message he wrote to all of you.

What an honor and privilege it was to have Zaxis in the shop to do a video on us and this new 10L1000 valve body as well as to be able to share just a little bit of testimony as to how God used the circumstances around me to turn my heart back to Him.
To say I am grateful is an understatement. We are blessed to be able to do what we do, to know the people in the industry we know, and to have had so many incredible people pour into me over the years, as well as having all the amazing loyal customers weve been able to have for the past 18 years of business.
I'd like to say a special thank you to our crew here at the shop. Weve had some incredible people come our way over the years but Adam has truly been a Godsend. This project and several more to come wouldn't have been possible without him and everyone else who's helped along the way. We have some amazing friends who have continued to believe in us, support us, and pray over us and for our business. You know who you are, and you're welcome! Hahaha!
There are some out there who believed in us so much so they stood by our side and pushed me to stay focused, head down and on task till it was complete. Thank you to those who financially contributed to keep us rolling when all I had was an idea and a halfway working model. You all will forever be family.
Lastly Id like to say thank you to my family. My wife who puts up with all my sides, LOL! To my kids who have missed out on so much of my time over the years while I have continued to fight my way up the ranks of this industry. I love and appreciate you all.

DNJ started in 2008 with an idea. After building transmissions his whole life, 3 generations deep, David had an idea about the governor pressure solenoids in Dodge transmissions. After many months of drawing, designing, having models made at a local machining shop, seeing how it fit and worked and making changes to make it perfect before releasing to the public, we knew making transmission parts wasn't easy. Its a hard route to go from an idea to a drawing on paper to a finished working model in hand. The DCF1 was that part.
Years later he saw a problem with the Dodge 68RFE valve body warping and decided a billet channel plate could resolve most, if not all the issues. He had no clue what was about to happen. DNJ was not prepared for the publics reaction and we failed by not being able to keep up with sales. That was our DCF2 & DCF2-19 channel plates. Now here we are with our DJAK 10L1000 valve bodies. We have learned from past mistakes. After designing, finding issues, redesigning, testing for over a year, before releasing to the public. Yes there was a few small issues in the beginning, ask any customer, we stand behind our parts 1000% if theres an issue, return it and we will send you a new part or refund your money for the part. We are proud to put our name on our DNJ parts. Our family has endured alot over the last 18 years since this company was started. At the end of the day, we know it all starts with an idea. Having those you call friends and family that support you along the way, that is what has kept us going. The customers who call and place orders,the friends who say hey is there anything I can do. They get it. They know the efforts, the hours of sleep lost, the ball games missed, the dinners at work instead of at home.
An idea has a long road to travel before its ready for the public. We know. If you have an idea, reach out to us. We know what its like to have haters, but also know what it means to have people in your corner supporting you. We want to support you. We want to see your ideas be made into a product you can hold in your hand. We started with making transmission parts, but we have grown into so much more. DNJ is a real small town, small family owned and ran business. Owners are born and raised in Missouri, we are proud to put a Made in USA sticker on ALL our products. We make real American made products, out of real American made materials, in real American made machines, with a real American machinest, who also happens to be a real Cad/Cam design guy as well. So if you have an idea, let us know, Adam, here at the shop would be happy to assist you. If you'd like we can help you with getting your idea made into a reality. All big and small companies started with an idea, we are here to make your ideas a reality. Check out the photos and see what we are capable of. You never know where you might see some of the work we've been able to do. One of them being a very well known sporting goods store we were fortunate enough to be able to assist with a few of their projects this year.

On Monday we will be closed, as our team pauses to remember and honor the brave men and women who made the ultimate sacrifice for our country.
Our freedom was not free, it was because of those individuals that lost their lives. Our thoughts and prayers go to the families who lost a loved one. We are forever grateful for their courage and selfless service.Wishing you a meaningful Memorial Day.

When we are not spending our days building transmissions or re-designing and manufacturing transmission parts such as THE FIRST 68 BILLET CHANNEL PLATE or THE FIRST 10 SPEED VALVE BODY, we are doing one offs and little odd jobs. Todays high light is what started as a small business, an original to our area, a little company that has dabbled in the fishing lure business. We were contacted about taking their lure molds and making some adjustments to fit their new machines. The Big Man himself said he wanted to stay in USA and a local as possible. Walnut Grove is almost as local to Springfield as you can get. Now since how this lure company is now a REEL (see what I did there) big company I am not able to say any names until they do their own publicity thing. But I did get the approval to talk about we are doing and pisting our own photos. So heres it is... Our parts are still running on our other machines but we have 1 machine that is working just on this. We are excited for this new endeavor. If you have an idea or a part that needs a little machine time spent on it, give us a call at 417-994-2333 option 1 or email us at [email protected].
