Welcome to PATC – Performance Automotive & Transmission Center
We offer many Performance and Heavy Duty Automatic Transmission Parts which may not be available elsewhere.
We work with different manufacturers in the development of stronger parts.
Using these parts we have developed Performance / Heavy Duty Transmissions in many different levels and types.
All PATC performance torque converters are manufactured in-house.
