I took my 2012 Camry SE in for an oil change two weekends ago, and they told me about the recall and did the software update while they had the vehicle. I definitely notice less vibration. I'm really happy with the results. Short answer: yes, do it. It doesn't take very long, but the results in my car were significant.
Here's a description of the problem:
Some 2012 Camry vehicles may exhibit an intermittent shudder when lightly accelerating after an
upshift around the following speeds: 26 mph (42 km/h) (4th), 36 mph (58 km/h) (5th) and/or 44 mph
(71 km/h) (6th).
A torque converter shudder is a brief shake or shudder in the vehicle when internal clutches apply inside the torque converter. They refer to this application of clutches as "lock-up." Often this problem is mis-diagnosed and sometimes they needlessly rebuild transmissions as a result.
A quick test
On many vehicles, one way to identify a torque converter shudder is lightly touching the brake pedal. While carefully maintaining vehicle speed with one foot, delicately apply the brakes with the other. If the shudder immediately stops, with brake application, the problem is likely the torque converter clutch. When the operating system sees brake application, most vehicles release the torque converter clutches. A trained transmission-service technician can also test for torque converter lockup using a specific vehicle scan tool. These tests are important as a slight engine misfire very often causes the same sensation and is may be mistaken for a torque converter shudder.
