The purpose of this bulletin is to introduce new changes for the 2007 model year 4T65E automatic transmission.
On July 18, 2006 (Julian date 199), a revised wire harness with a new temperature sensor clip was introduced into production. This new temperature sensor clip requires corresponding changes to the spacer plate assembly and wire harness assembly. Refer to SI for the proper spacer plate and wire harness assembly procedures.
