OUR PROCESS

We troubleshoot before
you waste money on parts.

The cheapest repair is the one that fixes the actual problem the first time. Here’s how every Big Tee job starts.
01

Listen

You tell us what you’re hearing, feeling, and when it started. No guesswork, no upsell.

02

Inspect & Test

Hands on the vehicle. Code scans, road tests, visual checks, and component testing.

03

Identify the Problem

We isolate the actual failure — not the symptom — before any part gets touched.

04

Explain the Fix

Plain English. Real numbers from Identifix industry-standard estimating data.

05

Complete the Repair

Mobile at your driveway or in-shop for heavier work. You decide.

Mobile

Mobile when it makes sense.

Diagnostics, brake jobs, suspension work, AC service, starters, alternators, batteries, sensors — we bring the tools to your driveway, your job site, or wherever the vehicle is sitting.

  • Driveway or job-site service
  • No tow needed for most repairs
  • Same-day diagnostic appointments
  • Decatur and surrounding cities
Shop

Shop-based when the job needs it.

Engine swaps, transmission swaps, drivetrain rebuilds, and anything that needs a lift or specialty equipment moves into the shop. Same mechanic, just the right environment for the work.

  • Engine and transmission swaps
  • Drivetrain and major repairs
  • Heavy truck and semi work
  • Multi-day jobs with secure storage

Three shops told me I needed a new transmission. Terrence pulled up to my driveway, diagnosed a bad solenoid, fixed it the same week. Saved me thousands.

Truck wouldn’t crank at 6am before a haul. Big Tee was there inside an hour, found the starter, had me rolling. He’s my mechanic for life.
Renee H. Stone Mountain, GA

Straight talker. Tells you what needs to happen now, what can wait. No upsell, no parts cannon. Rare combination these days.

STRAIGHT ANSWERS

Frequently asked, honestly answered.

Where do you provide mobile service?
Decatur is the home base. We regularly run mobile service across Atlanta, Lithonia, Stone Mountain, Tucker, Clarkston, Avondale Estates, Panthersville, Belvedere Park, and East Atlanta. If you’re close to that footprint, call and ask.
What kinds of vehicles do you actually work on?
Cars, SUVs, pickups, box trucks, semis, work vans, and full fleets. All years, all makes. Most mobile mechanics cap at passenger cars — Big Tee doesn’t.
Do you really do engine and transmission swaps?
Yes. Engine swaps, transmission swaps, drivetrain rebuilds, and major repair work are part of what we do. Heavier jobs run in-shop. Lighter jobs can go mobile.
My vehicle won’t start at all. Can you come to me?
That’s most of our diagnostic calls. We come to the driveway, parking lot, or job site, scan the system, test components, and tell you exactly what’s wrong before we touch a part.
When does a job go mobile vs. in-shop?
Diagnostics, brakes, suspension, AC, starters, alternators, and most general repair — mobile is fine. Engine swaps, transmission swaps, and anything that needs a lift or specialty equipment — that’s shop work.
How do you build your estimates?
We pull labor times and parts from Identifix Direct-Hit, the same industry-standard estimating data professional shops use. You get a real quote, not a number off the top of someone’s head.
