At this point, we’ve been slinging 68RFEs like it’s an Oprah Christmas special 😅

“YOU get a transmission! 👈
YOU get a transmission! 👉
EVERYBODY GETS A TRANSMISSION!” 🎉

Truck load of core transmissions headed back to WP Developments today!

Good news is… that means we ought to have a truck bed FULL of fresh builds ready for install by noon tomorrow 💪🔥

If your transmission is slipping, banging gears, or thinking about retirement… you better get on the schedule before the next load heads out 👀

Pulled this thing from the bushes last Thursday! With known blown head gaskets, we elected to just throw a set of batteries from the core pile in it and a saucy tune up and take it pulling! With one goal in mind, BLOW IT UP😎

364.42 for a solid second place against one of our customers Nicholas Ebert💪💪💪

TNT taking home 1st and 2nd is always good news!

Unfortunately we didn’t blow it up, so it looks like we will be hitting the pulls in Potosi in June to see if we can make it give up there😂😂😂

Thanks again to Madison County Pullers Association for putting on a BANGER truck pull! You all went above and beyond in every aspect and we can’t wait to be apart of the next one👏👏👏👏

Rolling into the weekend the right way. 🔥

Knocked out a Hamilton flat tappet conversion paired up with a Banks Monster intake—this setup is all about reliability, airflow, and getting these trucks breathing and running the way they should. 💨

No shortcuts, no half work—just clean installs and parts that perform.

At TNT Diesel Performance And Repair we’re here for the big power builds and the upgrades that keep your truck alive for the long haul.

If your valvetrain’s questionable or you’re still choking that motor with stock airflow… you already know what to do.

Built right. Runs harder. Lasts longer.

Another diagnostic complete🫡

Another one out the door. 🔥

We just wrapped up another WP Developments 68RFE 650HP transmission install and this truck is ready to handle the power the way it should’ve from the factory. Built for towing, built for abuse, and built to hold when the skinny pedal gets buried. 💨

If your 68RFE is slipping, hunting gears, running hot, or living on borrowed time… now’s the time to upgrade before it leaves you stranded.

At TNT Diesel Performance And Repair we don’t do shortcuts — we do it right the first time.

Huge thanks to Nick Beardin for trusting us with this repair. We appreciate the business. 🤝
