All DTT performance transmissions are built by a DTT trained technician with the highest quality parts, both internal and external and has redesigned and modified sections to accommodate the power that the Cummins engine produces. Here are some of the components that separate DTT diesel transmissions from the rest.

All DTT Transmissions come with the following:

• DTT custom performance valve body. All valve bodies are machine tested and tuned for each customer.
  
• DTT VB install kit – Includes voltage regulator and HD band strutt & anchor
  
• DTT TPS noise filter
  
• DTT 4.4 ratio lever
  
• Custom tailored clutch packs
  
• New band
  
• DTT Billet 3rd gear piston & custom pressure plate
  
• DTT Billet servo
  
• Custom servo spring
  
• DTT Billet accumulator piston
  
• All transmissions have new electronics
  
• DTT custom designed converter

Diesel Transmission Technology  believes that quality comes first and that is why special care is taken with parts design and precision assembly. DTT parts are designed by actual transmission builders that understand the function of the parts and how best to improve the system.

 Each transmission is first disassembled and meticulously cleaned by hand before being placed in our state of the art cleaning system to ensure all contaminants are removed before reassembly, critical components are inspected and checked with precision measuring tools to determine if machining or replacement is necessary.
Each transmission is reassembled using an array of speciatly equipment, some specially designed for the particular application so each component is correctly installed eliminating any guess work.
What this means for the customer is each transmission rebuild is given the extra attention required for a much higher quality unit.


Torque converters and valve bodies are also available as components, call us for lead times on these items.
