Built 10L1000 Transmissions and Installations in Long Beach, CA

If your 10L1000 is slipping, shuddering, or struggling to hold power, you already know these transmissions have weak points from the factory. You do not need another shop doing a basic service and sending you on your way. You need a 10L1000 built to handle torque, towing, daily driving, and tuned Duramax power without giving up.

At Inglewood Transmission, we build, rebuild, and install 10L1000 transmissions in house using upgraded parts and proven methods that eliminate the problems these units are known for. Our diesel specialists work on GM 10 speed trucks all week long, and we know what it takes to make them reliable.

Technicians who understand the 10L1000

Our Long Beach crew has rebuilt and installed hundreds of 10L1000 units across GMC and Chevrolet HD trucks. We use upgraded clutches, improved cooling, and revised methods that solve common problems like shuddering, harsh shifts, and overheated fluid.

There is no one size fits all 10L1000 build. We tailor every unit to how you actually use your truck. Whether you tow daily, run a mild tune, or want a stock feeling transmission that lasts, we match the converter, clutch setup, and shift calibration to your needs.
