Automatic Transmission Disassembly and Cleaning 

Our rigorous overhaul process does more than repair and recondition your transmission, it fully returns it to original factory specifications thanks to our knowledge, expertise, and procedures based on over 60 years’ experience as the sole UK and Ireland distributor for Allison Transmission. Our automatic transmission overhaul process includes a complete disassembly, including paint and rust removal from all parts and components.


Automatic Transmission Re-Assembly

The automatic transmission reassembly process includes using remanufactured/rebuilt parts and components and new wear parts (gaskets, seals, bolts, screws, etc.). All new parts used are always Allison Genuine Parts™. Our in-process inspection and tests adhere to inspection plans, Allison specifications, including documentation of key dimensions throughout the re-assembly process.
