Dear Mr. Trammell:

        We have limited our review of your filing to your contacts with

identified as state sponsors of terrorism, and we have the following comments.
Our review with
respect to this issue does not preclude further review by the Assistant
Director group with respect
to other issues. In our comments, we ask you to provide us with information so
we may better
understand your disclosure.

       Please respond to these comments within ten business days by providing
the requested
information or advise us as soon as possible when you will respond. If you do
not believe our
comments apply to your facts and circumstances, please tell us why in your
response.

       After reviewing your response to these comments, we may have additional
comments.


General

   1. You filed an October 1, 2018 Collateral Agreement as Exhibit 10.03 to a
Form 8-K dated
      October 1, 2018, and Schedule 3.06 to this agreement identifies Tenneco
trademarks in
      Syria and Sudan. Also, your April 10, 2018 membership interest purchase
agreement to
      acquire Federal-Mogul LLC appears to indicate that Federal-Mogul and/or
its
      subsidiaries may have engaged in dealings or transactions with Syria or
Sudan within the
      last five years. Syria and Sudan are designated by the State Department
as state sponsors
      of terrorism and are subject to U.S. sanctions and/or export controls.
You do not provide
      disclosure about those countries in your Form 10-K. Please describe to us
the nature and
      extent of any past, current, and anticipated contacts with Syria or
Sudan, including with
      their governments, whether through subsidiaries, customers, affiliates or
other direct or

         indirect arrangements.

      2. Recent news articles discuss Federal-Mogul's joint venture with
Russia's Kamaz. On
         page 15, you identify customers that represented more than 10% of
sales within the past
         three years. Please tell us whether the business from Kamaz as a
customer and joint
         venture partner would have represented 10% or more of sales of the
combined company
         following the acquisition of Federal-Mogul.

        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

        You may contact Jennifer Hardy, Special Counsel, at (202) 551-3767 or
me at (202) 551-
3470 if you have any questions about the comments or our review.
