Two problems related to automatic transmission control module have been reported for the 2000 Subaru Outback. The most recently reported issues are listed below.
"fuzzy logic" transmission controller is dangerously slow, inconsistent, and unpredictable. Scanning 19 inputs is excessive over-kill and removes much of driver's control and peace of mind.
Transmission computer failed, causing vehicle to lose control and jolt onto the oncoming lane, luckily there was no oncoming traffic and no accident.
