Transmission Repair in Boise, Meridian and the Surrounding Area

When your transmission starts slipping, grinding, or leaking, you can feel it — and ignoring those signs only leads to more damage. At Garry’s Automotive, we provide expert transmission repair for every make and model. Whether you drive a car, SUV, or light-duty truck, our ASE-certified technicians diagnose and repair transmission issues with precision and transparency.

Your transmission directs the engine’s power to your wheels. When it fails, the entire vehicle suffers. We use advanced diagnostic tools, manufacturer-grade equipment, and decades of hands-on experience to restore smooth shifting and dependable performance.

Transmission Problems Don’t Fix Themselves

A transmission rarely fails without warning. The earliest symptoms usually start small — delayed shifting, fluid leaks, or unusual noises. If caught early, repairs cost less and preserve your transmission’s lifespan.

Common signs you need transmission service:



Fluid leaking under your vehicle (reddish or brown in color)



Delayed or harsh shifting between gears



Whining, clunking, or grinding sounds while driving



Slipping out of gear or losing acceleration



Burning smell or overheated transmission fluid



Dashboard warning lights related to transmission performance

If you notice any of these symptoms, schedule an inspection right away. Our diagnostic process pinpoints the exact cause before damage spreads.

Our Diagnostic Approach

We believe in data-driven accuracy — not guesswork. Our technicians start every appointment with a digital vehicle inspection and full transmission diagnostic scan.

Here’s what that includes:



Electronic Scan

Retrieves transmission-specific codes and live data.



Fluid Check

Evaluates level, color, and contamination.



Visual Inspection

Looks for leaks, damaged seals, or worn mounts.



Road Test

Evaluates shifting quality, noise, and performance under load.

We share all findings with you. You’ll see photos, notes, and recommendations from our technicians so you can make an informed decision before any repair begins.

Rebuilds vs. Replacement — What’s Right for You

When a transmission fails completely, you may have two options: rebuild or replace. Our job is to help you choose the most cost-effective, reliable path.

A rebuild involves disassembling the transmission, inspecting every component, and replacing worn or damaged parts before reassembly. It preserves the original housing and typically costs less than full replacement.

A replacement uses a remanufactured or new transmission. This option may be ideal for vehicles with extensive damage or high mileage.

We’ll walk you through each choice, provide transparent pricing, and never push unnecessary repairs. Our priority is keeping your vehicle dependable — not selling you parts you don’t need.
