New Parts

Converter Ground Sleeve Every company wants to produce a "quality" product.

How "quality" is defined and achieved varies from company to company.

Our new part manufacturing quality standard is clear and simple. We achieve this through commitment and discipline.

Our Quality Standard:

  • Every new part we manufacture must Fit, Perform, and Endure like an OEM part and be indistinguishable in appearance from an OEM part.
  • Every part must be consistently manufactured to be without variation from part to part or batch to batch.


From the re-engineering process, material analysis and selection, to final coatings we take every step necessary to ensure that each TMC part looks, fits, and performs like the OEM.

Through documented manufacturing processes, scheduled inspection points, and expert machinists, we ensure that each part is produced consistently the same.

Our discipline and commitment to a clear quality standard means Trans Machine parts can be installed with confidence.
