Why Choose a Rebuilt Transmission for Your Buick Rainier? Rebuilt Buick Rainier Transmission for sale.

The Buick Rainier, produced from 2004 to 2007, was Buick’s first SUV and featured powerful V6 and V8 engines. As these vehicles age, transmission failure becomes common—especially in high-mileage models. A rebuilt transmission offers the performance and durability you need, without the high cost of a new one.

✅ Cost-Effective & High-Quality

Buying a rebuilt transmission saves you hundreds—sometimes thousands—compared to a brand-new or remanufactured unit. You get the performance of a new transmission at a much better value.

✅ Rebuilt to OEM Standards

Each Buick Rainier transmission is completely disassembled, cleaned, and rebuilt with brand-new seals, gaskets, clutch packs, solenoids, and other critical components. Units are tested for performance and durability before shipping.

✅ Warranty Included

Every rebuilt transmission comes with a limited warranty, so you can install it with confidence.

What Transmission Does the Buick Rainier Use?

Depending on your Rainier’s engine and drivetrain, it will typically use one of the following transmissions:

• 4L60E – Common with the 4.2L I6 engine (RWD or AWD)

• 4L65E – Used in models with the 5.3L V8 engine (especially AWD versions)

If you're not sure which transmission is in your vehicle, just provide your year, engine size, and VIN, and we’ll match you with the correct rebuilt unit.
