The 2005 Chevy Avalanche is available with different transmission and shift options, which can affect the number of transmission shift solenoids present.

However, generally, the 4-speed automatic transmission (4L60E) used in the 2005 Chevy Avalanche typically has a total of 7 transmission shift solenoids. These solenoids are used to control the activation and deactivation of the transmission's clutches and valves, allowing the vehicle to shift gears smoothly and seamlessly.

It's important to note that the number of transmission shift solenoids may vary depending on the year, model, and configuration of the Chevy Avalanche.

The solenoids are inside the transmission.
You may need a book and some special tools to make the repairs.

Have your transmission serviced which will include a filter change, fluid change and band adjustment.

the shift solenoids come as one assembly, they are located inside the transmission attached to the valve body, u must remove the pan from the transmission to access them, a very, very messy job on the gound..
