The 10L1000 valve body in the 2020+ GM trucks is a huge problem and if fixed quick enough can save your transmission from catastrophic failure. We have put together some of the best parts to fix these issues and have more holding power as well. Give us a call so we can keep you running down the road longer.

Our internet and phone are currently down. We will be returning missed calls and texts as soon as it is restored. Thanks for your understanding!

We finished up a transmission overhaul for one of the local school districts.
We’ve built a ton of the Ford 6R140s and they all work flawlessly and have tens of thousands of hard miles on them. It’s truly humbling to have the trust of the schools, farmers, construction guys and everyone else that depend on their trucks running correctly. Thank you!

We have 4 transmissions on the table this week. A wicked 68rfe and 5r110w build, plus another 5r110w and Allison. There are several more in line so we’re burning through these as fast as we can without sacrificing quality. A big thanks to all the customers that are being patient and understanding to the extreme amount of work that’s stacked up out here.

Next week: more 6r140 and 6l80 transmissions, bulletproofing a 6.0 powerstroke and diagnosing what other shops can’t fix.

Being able to make or modify parts sure makes life around here easier. We can do anything from everyday parts to performance parts and will soon have more machines to fill the front shop

We are still without power due to the storms yesterday morning. With the phones down and no lights we will be working on what we can in the shop but will be closed to the public until power is restored. You can call the shop phone at 4177614321 and leave a voicemail. Please be patient as this is putting us behind but rest assured that we will get to your truck as quickly as we possibly can.

Merry Christmas from our family to yours! The shop will be closed until the new year to spend some much needed time with our loved ones. Leave us a voicemail or text message if you are needing to get in contact over the next week. We will get back to you as soon as we can!
