Welcome to RADesigns Products LLC, Owner-Rory DesJardin
We manufacture and sell manual shift controllers and accesssories for the Aisin-Warner 4spd automatic transmissions. These transmissions are commonly known as AW4, A340 and 30-40LE. These transmissions have been used in Jeep, Toyota, Lexus, Isuzu, Suzuki and Volvo vehicles.

How did we get started?
When swapping in a A340 in my '83 Toyota I found the need to have a controller to shift the transmission manually since I didn't have the TCM or any way to connect it to the carburated 22R.
Not being able to find what I needed I made my own.

 
Evolution of the shifter.
Originally using toggle switches and diodes to be able to shift the transmission I wanted something more convienent and practical. So the RSS programmable controller was born. Using a PLC and learning Ladder Logic programming I created a shifting program. Although this worked great I still was on a quest for something simpler, so was born the Rail Shifter. Then after a conversation with a Jeepspeed racer I took it upon myself to create the Baja Shifter, a larger more rugged design with the off-road racer in mind. 
After a weekend of snow wheelin' I realized the inconvience of going from 1st or 2nd to reverse, so evolved the Rock floor shifter.
 Where are we going?
Since there is always something the off-road community needs or wants we'll be there to help supply those niche products. 
Of course we'll do this with out losing focus on the shifting products that were the start of our business. The Photo and Idea page often has new product ideas that are under development, if you have an need please feel free to contact us.
