Automatic Transmission

Whether you're doing an automatic transmission service or a major overhaul, ECS Tuning has the parts, fluids, and filters you need. Get original equipment or name brand aftermarket products that fit right and work as expected.

Axles

When repairs won't do, we have complete drive axles for your automatic or manual transmission. Order a new OE or aftermarket drive axle, plus any seals and attachment hardware needed for a complete installation.

Manual Transmission

Whether you're doing a manual transmission service or a major overhaul, ECS Tuning has the parts, seals, and fluids you need. Get original equipment or name brand aftermarket products that fit right and work as expected.

Mounts

For safety and smoothness, periodically inspect and replace all drivetrain mounts that show signs of looseness, cracking, or breakage. Worn, hardened, or broken mounts allow drivetrain components to move out of place, resulting in annoying noise, vibration and harshness. Broken mounts are also a safety hazard that can cause a loss of vehicle control and additional vehicle damage.

SMG Transmission

The Sequential M Gearbox (SMG) is a unique gearbox that can operate in fully automatic or manual modes. From paddle shifters to parts and fluids, ECS has the what you need to keep your SMG shifting smoothly.
