About the Toyota Corolla Transmission Computer (TCM/TCU/TRANSMISSION-CONTROL-MODULE)
The Transmission Computer (TCM/TCU) controls automatic transmission shifting, torque converter lockup, and gear selection. A failing TCM causes harsh shifting, stuck gears, limp mode, and transmission warning lights. The Transmission Computer (also known as TCM, TCU, TRANSMISSION-CONTROL-MODULE) is a critical component for your Toyota Corolla.
