Inside this 48re transmission gear train 👀

This video shows the difference between the stock thrust washer setup and our in-house rollerized modification using needle bearings.

The stock setup works — but over time flat thrust washers wear, create more friction, more heat, and increased play in the gear train.

Our rollerized machining modification helps:
✔️ Reduce friction
✔️ Reduce heat buildup
✔️ Maintain tighter thrust clearances
✔️ Reduce wear in the gear train
✔️ Improve durability and performance

You can actually SEE the difference in how freely the modified assembly spins compared to stock.

This isn’t just parts swapping — this is precision transmission machining and custom setup work done in-house at Dierks Diesel & Auto Performance by Levi, our machinist.

We specialize in:
• Transmission rebuilding
• Performance transmission upgrades
• In-house machining
• Custom modifications
• Diesel & gas vehicle repair
• Heavy duty drivetrain work

Whether you need diagnostics, machining, repairs, or a complete performance build, our team takes the time to do the deeper inspection and precision work that many shops skip.

A little behind-the-scenes Dodge transmission talk from Galen.

This is a 47RE Dodge transmission — the style used in many Ram diesel pickups from the early 90's up through the first half of 2003. Like Galen says in the video, these can be really strong transmissions, but they do have a few “Achilles heels” that need to be addressed when they are being repaired or updated.

One of those is the rear sprag race. If it gets loose and starts rattling in the case, it can turn into a much bigger repair than it needed to be. Taking care of these known weak points while the transmission is apart helps make the truck more reliable and gives the repair a better chance of lasting.

At Dierks Diesel & Auto Performance, we work on diesel trucks, gas vehicles, Dodge Ram diesels, Powerstroke, Duramax, Cummins, work trucks, RVs, farm rigs, classics, and everyday drivers.

If you need diesel repair, gas vehicle repair, transmission-related diagnostics, drivetrain work, a second opinion, or a full vehicle inspection, give us a call.

Serving Deer Park, Spokane, Chewelah, Colville, and the surrounding Eastern Washington area.
