Built to Beat the Heat: Drivetrain Direct’s Remanufactured 8L90 & 10R80 Transmissions

When it comes to modern transmissions, two of the biggest names in the game are the 8-speed 8L90 and 10-speed 10R80, found behind everything from Silverado 1500s to Mustangs and Raptors. But if you’re in the market for a replacement, used and backordered just won’t cut it.

That’s where Drivetrain Direct comes in.

We stock fully remanufactured 8L90 and 10R80 transmissions, ready to ship, dyno-tested, and built to handle the job like they should’ve from the factory.

 Why Our 8L90 Is a Cooler Choice

The GM 8L90 is a powerful transmission, but let’s be real: it’s had its share of heat-related issues.

That’s why every 8L90 we sell includes a bypass delete kit, which eliminates the factory thermal bypass valve that can restrict fluid flow when it’s needed most. The result?
Cooler temps. Smoother shifts. Longer life.

Add in our deep-dive remanufacturing process, with upgraded bushings, new seals, cleaned and inspected hard parts, and dyno validation, and you’re getting a transmission you can drop in and trust.

10R80: Thoroughly Rebuilt. Road-Ready.

The Ford 10R80 has become the backbone of the F-150 and Mustang lineups, but as miles stack up, they’re showing wear.

Our reman 10R80s go through the same no-shortcuts reman process as our 8L90s:

• Complete teardown & cleaning

• All wear-prone components replaced

• Vacuum-tested valve bodies

• Updated frictions and steels

• Final dyno test to verify operation

While the 10R80 doesn’t need the bypass delete, the quality control and consistency built into every unit sets ours apart from the pack.
