INDIANAPOLIS, Nov. 29, 2012 /PRNewswire/ --Allison Transmission Holdings Inc.
(NYSE: ALSN) announced that members of the International Union, United
Automobile, Aerospace and Agricultural Workers of America (UAW) Local 933
ratified a new five-year collective bargaining agreement (CBA) which becomes
effective December 3, 2012 and will expire on November 14, 2017.

Some of the key economic provisions from the new CBA include a $5,000
ratification bonus, maintenance of a multi-tier wage and benefit system, and
an annual incentive compensation program. Tier one and skilled tier two union
members will receive a lump sum payment equal to 3 percent of their base wage
in 2013 and again each year until 2016. Production tier two union members will
receive base wage increases ranging from 2 to 4 percent in 2013, 2015 and 2016
and a one-time 3 percent lump sum payment in 2014. Annual cost of living
allowances based on a variable consumer price index were eliminated and
replaced with a fixed annual lump sum payment of $1,000.

Pension rates under the CBA are unchanged and the company match for tier two
employee contributions to the 401(k) plan increased from 5 to 6 percent. The
parties also agreed to modify retiree healthcare, more closely aligning it
with the benefits offered in the Voluntary Employee Beneficiary Association
(VEBA) trust covering retired U.S. auto workers from Ford Motor Co., Chrysler
Group and General Motors Co.

The new CBA covers approximately 1,550 hourly employees who primarily work in
the Indianapolis area.
