Transmission Service

Modern transmissions are computers as much as they are gearboxes. We service DSG/DCT, ZF 8HP, ZF 6HP, Mercedes 7G/9G, and manual transmissions with the correct fluids, filters, and adaptation procedures so the gearbox actually learns again after the service.

Signs you need transmission service service

  • Harsh, delayed, or slipping shifts
  • Shudder during light acceleration or at cruise
  • Transmission warning light or limp mode
  • Clutch pedal feels heavy, vague, or chatters
  • Burnt smell or red/brown fluid drips
  • Manufacturer service interval is due (every 40k–60k for most)

What we do

  • DSG/DCT service with OEM fluid and filter
  • ZF 8HP and 6HP automatic fluid and pan service
  • Mechatronic and TCM coding and adaptation reset
  • Manual transmission, clutch, and flywheel replacement
  • Differential and transfer case fluid service
  • Driveshaft, axle, and CV joint repair
Why Denver chooses us

We use the OEM fill procedure with the correct fluid temperature, then run a proper adaptation drive cycle — not a quick drain-and-fill that leaves the gearbox confused.
