  • Signs for push-out forces
  • After almost eleven years on the job
  • Laud, praise and thanks for Dewey
  • Search for a successor

( — Indianapolis, Indiana, December 21, 2016 — Larry Dewey, chief executive of Allison, leaves. His departure is made public at an early stage. As announced by Allison Transmission Holdings Inc. in a news release and in a regulatory filing published on Wednesday, December 21, 2016, Lawrence E. (Larry) Dewey, Chief Executive Officer, leaves the manufacturer of fully automatic transmissions for commercial vehicles after almost eleven years on the job, effective May 31, 2018.

It is the end of an era.

Allison will undertake a search for a successor.

Long goodbye

It is a long goodbye. The announcement of Dewey’s move comes 17 months prior to his planned departure.

In general, a top executive who announces the departure very early may be considered a lame duck.

Lengthy lead times give boards extra time to find replacements, and they also create uncertainty. Would-be successors may jockey for attention and workers may wonder who is actually in charge.

Generally speaking, lame-duck leaders can take a forceful role in selecting a successor and are not expected to launch major strategy shifts.

No reason given

In the announcement, Allison did not explicitly explain the reason for Dewey’s move, opening the door for speculation.


Allison said: “The board of directors for Allison Transmission Holdings Inc. … today announced that it has entered into a new employment agreement with Chairman and CEO Lawrence E. Dewey. The agreement runs through May 31, 2018 at which time Dewey, currently 60 years old, intends to retire.”

Precise information about the future plans of Dewey was not immediately available.

On the job as CEO since 2007

Dewey will be retiring after a career spanning 44 years, which includes serving as CEO since August 2007.

Dewey joined Allison in February 1989.

Dewey currently serves as the Chairman and Chief Executive Officer of Allison and has served in that capacity since January 2016.

Before joining Allison, Dewey held several positions of increasing responsibility in General Motors’ Diesel Equipment Division and Rochester Products Division.

He began his career in 1974 as a General Motors co-op student at General Motors Institute (now Kettering University).


As a general rule, when a top leader announces to step aside with no successor in place, it is a sign that the move was unexpected and too early.
