High Quality Transmission Rebuilds

- Our work is backed by a solid warranty
Why Our Transmission Rebuilds Outperform Others
Our transmission rebuilds stand out because we take the extra steps most shops skip. We don’t just replace worn parts—we upgrade them with stronger components designed to outlast factory specifications. When we say “completely disassembled,” we mean it: every valve, solenoid, and clutch pack is individually inspected and either upgraded or replaced.
The common failure points we address include transmission valve bodies that develop internal leaks, solenoid packs that fail prematurely, and friction materials that wear unevenly. By reinforcing these vulnerable areas, we prevent the same problems from happening again.
Our testing process goes beyond basic road tests. We use advanced diagnostic equipment to verify proper shifting patterns, pressure readings, and temperature management before your vehicle leaves our shop. This thoroughness ensures you won’t experience unexpected problems after the repair.
The 2-year/24,000-mile warranty reflects our confidence in our work. Unlike remanufactured units that use the same parts that failed initially, our custom rebuilds are engineered to provide reliable service well beyond the warranty period.
For transmission repairs in Marietta that truly last, trust the specialists at Guardian Transmission. We don’t just fix your transmission—we improve it.
