Some 2012-2014 Toyota Tacoma vehicles equipped with the A340 automatic transmission may exhibit a shudder condition on deceleration at about 20 mph.

The engine control module (ECM) logic has been modified to reduce the possibility of this condition. Reprogram the ECM, using Techstream 2.0, TIS Techstream or Techstream Lite and software version 9.10.037 or later.
