Friendly reminder: If your transmission builder tells you to leave it on tune 1… it wasn’t built right.

🔥 Stage 1 AS69RC headed to Kentucky! 🔥

Built in-house and ready to handle serious power, this Stage 1 AS69RC is leaving Texas and making its way to Kentucky — and it’s packing heat.

This unit is equipped with a Goerend billet quad disc torque converter, giving it:

• Stronger lockup holding power
• Improved towing performance
• Reduced slippage under load
• Increased durability over stock

When you’re building an AS69RC, the converter is everything — and Goerend’s billet quad disc is one of the best in the game. Perfect for daily driving, heavy towing, and tuned trucks that need reliability without sacrificing performance.

Ethan Perry is absolutely abusing this 1500HP+ TDP transmission and it just keeps taking it. Flux Diesel Injection injectors are running flawless and clean, keeping this combo happy pass after pass. Big things coming as we keep dialing this setup in!

If it’s freezing outside and you fire your truck up, slam it into gear, and floor it like you’re chasing 2nd place at the Daytona 500… you deserve the rebuild that’s coming. Cold ATF is thick. Seals are stiff. The hydraulics haven’t woken up yet. That “built transmission” isn’t magic, it’s mechanical, and mechanical parts don’t like being abused in the cold. Warming the truck up costs you 20 minutes. Not warming it up can cost you thousands. Put some heat in it before you try to pass Dale.

This build has been a long time coming — and we couldn’t be more proud of how it turned out.

When Ethan came to us wanting to take his 2003 Ram to the next level, we said look no further. Using the best brands and components in the industry, we built a truck that delivers consistent, reliable power and still has plenty left on the board.

Powered by our in-house assembled long block and backed by our 1500+ FMVB 48RE, this setup shows exactly what happens when precision meets performance. We’re currently sitting at 1600µs on these Flux Diesel Injection 175%’s , and this thing is just getting started. 💪🔥

Today is Cade’s one year anniversary at Thompson Diesel! When Cade started he was ambitious to learn but knew very little about a diesel engine, the amount of knowledge on the diesel industry Cade has retained and learned is insane!

From the Thompson Diesel crew we appreciate the hard work and dedication you have brought this year! We look forward to what you bring in the coming years!
