🔥 GTO IS DONE! MORE ISSUES FOUND. ALL FIXED. 🔥
You may remember this 2006 Pontiac GTO from our previous post. It originally came in with an ATF leak and drivetrain noise/rattle, which led us to an incorrectly fitted aftermarket shifter that wasn't sealing properly and had no rubber isolation to keep normal transmission noise out of the cabin.
But this GTO had a few more things for us to find. 👀🔧
The customer requested a thorough inspection, and that's exactly what we gave it.
🔍 2 HOURS OF DIAGNOSTIC TIME INCLUDED:
✅ Road test & drivetrain/noise diagnosis
✅ Transmission & ATF leak inspection
✅ Steering, suspension & driveline
✅ Brakes, parking brake, hubs & bearings
✅ CV axles, differential & mounts
✅ Exhaust/header clearance
✅ Cooling system, hoses, belts & fluids
✅ Tires & undercarriage
✅ A/C system diagnosis
🛠️ REPAIRS & SERVICE COMPLETED:
✅ Correct shifter installed & properly sealed
✅ Rubber shift boot/isolation added to reduce cabin noise
✅ Front sway-bar links replaced
✅ Cracked/glazed parking-brake shoes replaced
✅ Coolant hoses replaced
✅ Complete heater-hose kit installed
✅ Customer-supplied alternator installed
✅ Leaking A/C Schrader valve replaced
✅ A/C evacuated & recharged — BLOWING COLD! ❄️
We also found several things that didn't need replacing. The service brakes, rotors, hubs/bearings, tires, belts, CV axles and differential all checked out. 👍
💡 And we don't double-charge overlapping labor. When disassembly performed during diagnostics carried over into an approved repair, that was accounted for in the repair labor.
That's why diagnostics matter: find the real problems, don't sell what the car doesn't need, and make the right repairs. 🎯
This GTO came in with a list.
It's leaving with a much shorter one. 😎🔥
