Who is MDL?

Modern DriveLine has been servicing the Ford, GM, (and more) performance community since 1998.


Our Business Philosophy

At Modern DriveLine our goal is to provide top notch service. We do this by providing high quality products backed by top customer service. With these products comes loads of solid advice.

Our business is built on word of mouth. We hope you will tell a friend about us when you receive good service and advice. 

Our Company

Our business started out of need. Being a part of the Shelby Club of Northern California, it was apparent that there was a need for a company focused on the modern overdrive transmissions that understands the needs of high performance, and not so high performance owners. Working for Charlie's Mustangs in the 90's, Bruce began repairing T-5 transmissions. In 1996 Bruce purchased a 65 Mustang hardtop that needed restoring. It was equipped with a V8 automatic. After driving the car for a year, he decided the car needed a manual transmission. A T-5 five speed was chosen for it's size and drivability. While searching for conversion parts, he found there were very few companies offering five speed conversion parts or complete packages. It was this search that showed a need for better fitting parts that are easy to install and long lasting.

We have added to the lineup from the T5/Mustang beginnings and now offer many new applications and continue to work on new projects. We now address the six speed market, as well as, Falcon's, Cobra's, trucks, Hotrods  and Big block, small blocks, six cylinder, Y-blocks and flathead conversion parts and packages.  We continued broadening the product line in 2008 with GM and Mopar components, with more being added each month.   In 2009 we introduced the LF series hydraulics to meet the needs of the market.

Modern Driveline has been in business since 1998. Hundreds of transmissions have been rebuilt, and custom built. Our products are now installed in well over 10,000 vehicles, ranging from model A's to current production vehicles across the country and in foreign countries.  Modern Driveline is here to service you with your driveline conversion needs whether it is a stock 6 cylinder or a high performance V8 or anything in between.  Convert your classic to a modern Hotrod today.

The Man behind the Name

Hi, my name is Bruce Couture.  I believe that a business is only as good as the people behind it. I have been installing high performance parts on early and late model Mustangs since 1996. In 1996 I worked with Charlie's Mustangs in San Jose, CA. While there I installed superchargers, Baer brakes, EFI conversions, mass air system's in F series trucks, six speed conversions and more. If it was a V-8 or larger, Charlie's shop made it faster.

In my off hours I run a late model Mustang ('92 LX  "the Blue coupe") set up for open tracking. It sports a supercharged 327 stroker producing 486hp at the rear wheels.  All that power is handled with a T5z.  The latest addition to the stable is the tow rig, a '74 Ford Econoline Van with a fuel injected 410, with an automatic and Gear-vender overdrive (now retired as the tow rig having been replaced with a 2007 F350).  And the car which started it all, the poppy red '65 Mustang hardtop, is driven to, and has been shown at many events around the San Francisco Bay Area put on by the NorCal Shelby Club and other area clubs, as well as events in the Northwest states of Oregon, Idaho, Washington, Nevada and Utah. 

2015 saw the completion of a red '84 Mustang convertible which Charlie had dis-assembled in the early 90's.  After many years of sitting and moving from California to Idaho, time was found to work on putting the car back together as Charlie would have wanted it.  2015 was the year the paint was applied and the rubber hit the road  for the first time in 20-some years.

The most recent change for Modern Driveline is the relocation to Idaho which took place over 2006-2007.  We now reside in Caldwell, which is just west of Boise, Idaho. We are now fully moved into, and operating out of, a new shop continuing to bring innovative new products to market and giving our customers the best in products and services.

Keep an eye open at your next Mustang car show on the west coast. There is a chance you will see either the poppy red '65, the "Blue Coupe", or the red '86 convertible.  If you do, be sure to say hi. ~Bruce
