Our history
Our history in Whitehall, PA
1992: Founded on engine and transmission work

1994: Stephen Lang, Jr. joins
Stephen Lang, Jr. joined in 1994, bringing experience in diagnostics and general repair from his years at Lang’s Gulf. He bought the shop in 2011.
2011 to today: Derek J. Lang
His son, Derek J. Lang, joined the same year and took over management of the office in 2012. Derek bought the business in 2017. He has kept the shop’s commitment to engine and transmission repair and expanded its general maintenance and repair work. Today the shop runs seven bays with four full-time technicians.
How we work
A fair diagnosis and honest repair
We only repair what needs repairing
Our technicians use high-tech diagnostic tools to find where the problem is. Then we explain what we found, clearly, and you get fair, transparent service.
A maintenance schedule that fits you
Whether you drive many miles for work or take the car out on weekends, we build an individualized schedule around your needs, with the fewest visits possible.
Quality parts on every job
We use quality parts and materials on every repair, every maintenance visit and every engine replacement. That is how a vehicle stays on the road longer.
