Transmission Control Switch Circuit [10/2017 - 09/2020]: Description

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2024 Lexus IS 350, 2023 Lexus IS 350, 2022 Lexus IS 350, 2021 Lexus IS 350, and 2020 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control switch detects when the shift lever is moved to M.

Using the transmission control switch, when the shift lever is in M, it is possible to select between 1st and 8th gears (M1 to M8).

Moving the shift lever to "+" once selects the next higher gear, and moving the shift lever to "-" once selects the next lower gear.
