Transmission Repair & Service in Sandy, OR

Reliable Transmission Diagnostics, Maintenance & Repairs

Your transmission is one of the most important—and complex—systems in your vehicle. When it begins to slip, jerk, or make unusual noises, it’s critical to have it inspected right away. At Sandy Automotive & Exhaust, our technicians provide expert transmission diagnostics, fluid service, leak repair, and full transmission replacement for cars, trucks, SUVs, and 4x4s.

For over 20 years, drivers in Sandy, Gresham, Boring, Welches, and the Mt. Hood corridor have trusted us for honest assessments, high-quality repairs, and reliable service that keeps their vehicles running smoothly.

Whether your transmission is showing early warning signs or has failed completely, we’ll identify the issue and get you back on the road safely.


Signs You May Need Transmission Repair

If your transmission is having problems, you may notice:

Slipping gears

RPM increases without acceleration.

Delayed or harsh shifting

Rough gear changes are a top warning sign.

Transmission fluid leaks

Often bright red or pink fluid under the vehicle.

Burning smell

Overheated or degraded transmission fluid.

Shaking or grinding

Especially when shifting or accelerating.

Vehicle won’t move in drive or reverse

Indicates major internal failure.

Check Engine Light or transmission warning light

Often tied to solenoid or internal pressure issues.

If you notice any of these symptoms, don’t wait—transmission problems get worse quickly.


Complete Transmission Repair & Service

We service both automatic and manual transmissions, as well as CVT, AWD, and 4×4 drivetrain systems.


Transmission Diagnostics

We use industry-leading diagnostic tools to analyze:

  • Transmission control module codes
  • Fluid temperature & pressure
  • Shift solenoid behavior
  • Gear ratios & slip detection
  • Live data and performance readings

This allows us to pinpoint the exact issue—no guesswork.


Transmission Fluid Change & Flush

Clean fluid is essential to transmission health. We offer:

Transmission fluid change

Replaces old, burnt, or contaminated fluid.

Full transmission flush

Removes sludge, debris, and build-up from inside the system.

Filter replacement

Ensures proper fluid flow and protection.

Routine service dramatically extends the life of your transmission.


Transmission Leak Repair

Transmission leaks often come from:

  • Worn gaskets
  • Damaged seals
  • Pan gasket failure
  • Coolant line issues
  • Axle seals
  • Torque converter leaks

We find and fix leaks before they cause overheating or low-fluid damage.


Transmission Component Repair

We repair and replace:

  • Shift solenoids
  • Valve bodies
  • Sensors
  • Gaskets & seals
  • Bands
  • Mounts
  • Cooling lines

These components commonly fail and can often be repaired without replacing the entire transmission.

High-quality rebuilt transmissions

Factory-spec rebuilds with reliable performance.

Used (low-mile) transmissions

Budget-friendly options when appropriate.

New transmissions (when available)

OEM-level quality and longevity.

We work with you to find the best option for your vehicle and budget.
