For over 40 years Transmission Specialties has been the trusted name in the performance automatic transmission industry. TSI has pioneered much of the technology that is now commonplace in the transmission marketplace. The inventors of the spragless converter and the aftermarket Powerglide planetary, TSI is known worldwide for manufacturing and assembling the highest quality transmissions and components.

Our “entry level” Turbo 400 transmission features many high-end items that other companies charge extra for. Assembled to the same exacting specifications as our top of the line transmissions, these units are without a doubt the best value for your money, while still providing you a transmission you can trust to put the power to the ground!

Unlike many production builders, our transmissions are handcrafted from beginning to end by one highly skilled and experienced technician. This process ensures that you the customer gets the highest quality product each and every time. This unit has undergone over 40 years of contiguous, rigorous R&D and on track testing.
