                         TRANS-INDUSTRIES, INC. REPORTS
                           FIRST QUARTER 2004 RESULTS

ROCHESTER HILLS, MICHIGAN -- MAY 7, 2004 - TRANS-INDUSTRIES, INC. (NASDAQ:
TRNI), a leading manufacturer of interior bus lighting products, electronic
information systems and software, plus dust extraction systems and related
components for the mass transit and highway markets, today announced results for
the first quarter ended March 31, 2004.

Sales for the quarter totaled $7.5 million compared with $8.6 million for the
same period last year. Most of this decline was attributable to the information
systems and environmental systems businesses with modest shortfalls registered
by the lighting and mechanical signage units. On this reduced volume, a net loss
of $267,000, or $.09 per share, was incurred compared with a loss of $473,000,
or $0.15 per share, for the comparable quarter last year. For the 2004 first
quarter, the information systems and environmental products operations together
recorded a net loss of more than $500,000, which was only partially offset by
other operations.

Profit improvement efforts initiated during the middle of last year are
continuing with estimated annual reductions, on the basis of first quarter
expense levels, to be in excess of $2.5 million.

ABOUT THE COMPANY

The Company is a leading provider of lighting systems and related components to
the mass transit market as well as a supplier of information hardware and
software solutions on Intelligent Transportation Systems (ITS) and mass transit
