Not Every Shifting Problem Means a Rebuild

A transmission that slips, flares between gears, thumps into drive or refuses to shift into overdrive is worrying. Sometimes it is serious. Often it is low or burnt fluid, a solenoid, a sensor or a software issue that costs a fraction of a rebuild.

Transmission work at Auto Repair Dumont starts with a scan, a fluid check and a road test that recreates the problem. Automatic, manual and four-wheel-drive units all get the same treatment. Only when testing shows internal damage does a rebuild or replacement come into the conversation. Steep grades and towing heat fluid quickly, so fluid condition is always one of the first things checked.

What Transmission Work Covers

Depending on the diagnosis, the repair can be any of these:

  • Transmission diagnosis

    Codes, fluid condition, pressure readings and a road test pin down whether the fault is electrical, hydraulic or mechanical.

  • Fluid and filter service

    Old, burnt fluid is replaced and the filter changed, which fixes more shifting complaints than people expect.

  • Solenoid and sensor repair

    Faulty shift solenoids and speed sensors are replaced without opening the transmission.

  • Leak repair

    Pan gaskets, cooler lines and seals are replaced to stop fluid loss before it starves the unit.

  • Clutch replacement

    Manual transmissions get clutch, pressure plate, release bearing and flywheel service.

  • 4x4 and transfer case work

    Transfer case faults, engagement problems and leaks on four-wheel-drive trucks and SUVs.

  • Transmission rebuild

    Worn clutches, bands and seals replaced inside the unit when internal wear is confirmed.

  • Transmission replacement

    A replacement unit installed when it is the better value than rebuilding the original.

How Transmission Repair Works

  1. Recreate the problem

    We drive the vehicle with a scanner connected to see exactly when and how the shift goes wrong.

  2. Narrow it down

    Fluid, electrical and pressure tests separate a simple fix from internal damage.

  3. Repair and verify

    After approval, the fix is completed and the transmission is road-tested through every gear.
