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 92 Mustang 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 with a single disk 10.5″ Kevlar clutch.  The car that really started Modern Driveline is my 65 Mustang Coupe. The car came to me as a unfinished project.  Shortly after restoring the car, I decided the automatic wasn’t choice for me.  I decided a T-5 five speed was a better choice.  After find almost nothing to install a five speed in a classic Mustang, start developing all the supporting parts to do so.  This lead to other with the NorCal Shelby Club to take notice and a business was born.  Many of the parts we develop are build on my own small collection of cars. Our clutch cable kit, crossmembers, hydraulics kits were all fitted to my personal cars before being released as product for MDL.  If its not good my car, its not good enough to sell.

2015 saw the completion of a red ’86 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.

In 2007 Modern setup shop in Caldwell Idaho to allow us do things that were not as easy in CA. In the last 13 years MDL has grown to business of over dozen staff members and over 10,000 square foot layout.  All of this has allowed up to future develop new products, build in house brand clutches and better service our customers.

MDL has been a Tremec Elite distributor since 2008 allow us to purchase directly from Tremec for both transmission assemblies and service parts.  Currently we have a service center repairing Borg Warner T-5, T-45, T-56 as well as Tremec 3550, and 3650.

Modern DriveLine is proud to celebrate over 21 years in business, making us one of the oldest 5 & 6-Speed Conversion Specialists today!  We have a warehousing full of the many items that customer need to complete their project fast.
