Transmission

Slipping, harsh shifts and shudder rarely fix themselves. We diagnose whether it is fluid, a solenoid, a valve body or the unit itself before recommending anything.

What we look at first

Transmission problems get expensive fast when they are guessed at. A shudder can be a torque converter, worn fluid, a solenoid, an engine misfire being felt through the driveline, or a mount.

Diagnosis comes first: fluid condition, transmission codes, live data on line pressure and shift commands, then a road test to confirm what the data suggested.

Sometimes the honest answer is a service and a solenoid. Sometimes it is a rebuild. You will be told which, and why, before the transmission comes out.

What we actually do

  • Fluid condition and level checked properly, at temperature.
  • Transmission codes and live shift data read and interpreted.
  • Road test to confirm the fault matches the data.
  • Service, solenoid and valve body work where that is the real fix.
  • Rebuild or replacement coordinated when the unit is genuinely done.

Symptoms worth acting on early

  • Slipping or flaring between gears
  • Harsh, delayed or hunting shifts
  • Shudder at steady cruising speed
  • A whine or grinding that changes with gear
  • Burnt-smelling or dark fluid
  • A transmission warning light or limp mode
