What transmission does a 2006 Toyota Avalon have?

The 2006 Toyota Avalon uses a 5-speed automatic transmission (5AT) paired with a 3.5-liter V6 engine.

In 2006, Toyota transitioned the Avalon to a more modern electronically controlled five-speed automatic paired with a 3.5L V6 (2GR-FE). This setup drives the front wheels and includes a Sport/Sequential mode for manual-style gear selection, delivering smooth highway performance. For maintenance, owners should follow the exact transmission fluid specifications and service intervals listed in the vehicle’s owner manual.

Transmission details

Here are the core characteristics of the 2006 Avalon's transmission setup:

Type: 5-speed automatic transmission (ECT) with electronically controlled shift logic

Engine pairing: 3.5L V6 (2GR-FE) matched to the transmission

Drive layout: Front-wheel drive (FWD)

Shift modes: D (Drive) and S/Sequential mode for manual-style gear selection

Torque converter: Hydraulic torque converter with lock-up clutch

Fluid guidance: Uses Toyota automatic transmission fluid (ATF) per the owner's manual specifications

In summary, the 2006 Avalon's drivetrain centers on a reliable 5-speed auto paired with a robust V6, delivering smooth acceleration and efficient highway performance.

Maintenance considerations

Keeping the transmission healthy involves following Toyota's service recommendations and watching for common symptoms of wear or fluid issues. Here are the key points to keep in mind:

Regular transmission fluid checks and changes at the intervals specified in the owner's manual (typical guidance ranges from roughly 60,000 to 100,000 miles depending on driving conditions)

Watch for signs of trouble: delayed engagement, slipping, hard or late shifting, strange noises, or warning lights

Ensure the vehicle is serviced with the correct ATF type and a qualified technician, as improper fluid can cause shifting problems

Avoid aggressive driving, overloading, or towing beyond the design limits, which can stress the transmission

Correct maintenance helps extend the life of the transmission and reduces the risk of costly repairs.

Summary

In brief, the 2006 Toyota Avalon uses a 5-speed automatic transmission (ECT) paired with the 3.5-liter V6 engine. This setup, combined with front-wheel drive and Toyota's shift logic, was designed for smooth performance and reliability throughout its production. Always consult the owner's manual for the exact fluid specification and service intervals for your specific vehicle.
