How the job goes

  1. Describe it

    What the truck does and when it does it tells us a lot.

  2. Diagnose

    We check fluid, linkage, clutch, air supply and fault codes.

  3. Repair

    Many shifting and clutch problems come down to parts we can replace on site.

  4. Plan

    If it needs a rebuild, you get a clear answer and a plan.

Good to know

Transmission removal and rebuilds are shop jobs. Diagnosis comes first so you are not paying for a rebuild you do not need.
