Aftermarket & Remanufactured Parts for Allison Transmissions

To ensure that Trans Machine parts are the best aftermarket parts available for Allison transmissions and equal in every way to a genuine Allison part, our new aftermarket parts must meet the following criteria:

  • Virtually indistinguishable in appearance from an OE part
  • Produced from the same material or a tighter tolerance grade of the same material as the OE part
  • Dimensionally the same as the OE part with less dimensional variation than found in a sampling of the OE part
  • Manufactured under controlled processes to produce identical parts within each production run and over every production run

These are the hallmarks of the Trans Machine Quality Standard for our New Aftermarket Allison Hard Parts.
