Brendon getting Ty Bonin's truck wrapped up with a full manual valve body shifter install.

Just one of those jobs where the little details make all the difference. We appreciate Ty trusting us with his build and look forward to seeing the power this truck makes!!

Another clean 2002 Dodge Ram 3500 finished up and back on the road for our customer, Adolfo.

We got this truck equipped with our Stage 2 48RE, built to address the common weak points these transmissions are known for. This setup is designed to handle increased torque while still maintaining smooth, dependable shifts whether the truck is towing or driven daily.

We appreciate Adolfo giving Thompson Diesel Performance the opportunity to get him back up and running. If you’re looking for a reliable transmission built to work, give us a call at 254-709-9531 for all of your transmission needs.
