Gold River's Independent Transmission Experts
Your transmission is the most mechanically complex system in your vehicle. A slipping gear or burning smell is not something to defer — left unaddressed, a minor solenoid fault becomes a full internal failure that costs three times as much to repair. At 916 Auto Repair, we bring dealership-level diagnostic capability to an independent shop that actually explains what it finds and charges you fairly for it.
Comprehensive Transmission Diagnostics & Rebuilds
Most shops plug in a code reader and hand you a repair order. We go further. Our diagnostic process starts with a live scan using professional-grade OBD hardware that reads transmission control module (TCM) data in real time — shift timing, solenoid duty cycles, fluid temperature, and torque converter lock-up behavior. That data tells us whether your complaint is electronic, hydraulic, or mechanical before we ever pull the pan.
For vehicles presenting with delayed engagement, harsh shifts, or slipping between gears, we perform a road test under load to replicate the exact condition. This matters because transmission faults are often intermittent — they appear under specific throttle positions or temperatures and disappear when the car is cold. We document every anomaly and build a complete picture so there are no surprises once the teardown starts.
- Precision diagnosis of slipping gears, delayed engagement, and transmission fluid leaks.
- Specialized rebuild services for European (BMW, Mercedes, Audi) and Domestic transmissions.
- Complete fluid exchange services to extend the life of your drivetrain.
- Transparent reporting on whether a repair, rebuild, or replacement is the most cost-effective path.
What a Rebuild Includes
A transmission rebuild at 916 Auto Repair is not a partial refresh. When we open the unit, we replace every friction disc, steel plate, seal, and O-ring as a matter of course. Clutch packs are measured and replaced to OEM clearance specs. The valve body is cleaned, tested, and solenoids are replaced if worn. Torque converter condition is assessed — if end-play or lock-up clutch wear is detected, it is rebuilt or replaced rather than returned to service.
European Platform Expertise
BMW ZF 8HP, Mercedes 7G-Tronic Plus, and Audi DSG units require manufacturer-specific tooling and calibration procedures. Our technicians are trained on these platforms and stock the correct OEM-spec fluids — Pentosin, Shell M-1375.4, and Esso ATF LT 71141 — so you don't pay dealership labor rates for the same work.
Fluid Exchange vs. Flush
We perform drain-and-fill fluid exchanges, not high-pressure machine flushes. High-pressure flushing can dislodge debris and force it into small hydraulic passages, causing solenoid damage in already-worn units. Exchanges are safer, can be repeated in intervals on high-mileage vehicles, and extend service life without the risk.
The 916 Auto Repair Transmission Process
We follow a structured four-step process for every transmission job — from the first diagnostic visit through final delivery. This protocol ensures nothing is missed, every repair decision is documented, and you have a complete service record for your vehicle.
Initial computer scanning and road testing to pinpoint electronic vs mechanical failure.
Detailed inspection of the torque converter, planetary gears, and valve body.
Usage of OEM-spec fluids and high-durability replacement components.
Final calibration and multi-point safety check before vehicle release.
Rebuild Warranty
All transmission rebuilds at 916 Auto Repair are backed by a written parts-and-labor warranty. We use high-durability friction materials and OEM-spec components — not economy rebuild kit parts. If a warranty concern arises, bring the vehicle back and we make it right, no charge. Ask our service advisors for current warranty terms when you drop off your vehicle.
