Lock-Up Function
WARNING: This page is about a different car, the 2003 Subaru Outback, 2003 Subaru Legacy, and 2003 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.
Check that rpm does not change sharply when the accelerator pedal is lightly depressed when driving on flat roads at normal speed in the lock-up range.
