The problem: Affected Toyota cars may exhibit a brief, intermittent transmission shudder while driving under light loads between 25 and 50 mph. This is due to a combination of an engine control module software glitch and a faulty torque converter in the vehicle.
Corrective action: Toyota dealers will replace the torque converter and update the ECM software.
Warranty info: This repair is being done under the Toyota powertrain warranty of five years or 60,000 miles, whichever comes first.
