Transmission replacement and repair for the way you drive.
Your transmission turns engine power into motion, and when it starts slipping, hesitating, or grinding, it rarely fixes itself. At American Auto in Sugar Land, every transmission job starts with a full diagnostic of your gears, fluid, seals, and electronics.
If we find a problem, you get a clear, honest assessment and the right path forward: repair, rebuild, or full replacement. We use high-quality parts and manufacturer-recommended procedures.

Warning Signs
Signs your transmission needs attention.

Grinding or Shaking
Grinding, whining, or shuddering under acceleration can signal internal wear or mount problems.
Burning Smell
A hot, burnt odor after driving may mean overheating or burnt transmission fluid.
Leaking Fluid
Red or brown fluid spots under where you park can come from seal or gasket failure.

FAQ
Frequently asked questions.
Answers to common transmission repair, rebuild and replacement questions.
Should I repair, rebuild, or replace my transmission?
It depends on the extent of the damage and the age and value of your vehicle. Minor issues like a solenoid or seal can often be repaired. Significant internal wear may call for a rebuild, while severe damage can make replacement the smarter long-term choice.
How do I know if my transmission is failing?
The most common signs are slipping gears, delayed or hard shifting, grinding or shaking, a burning smell, leaking fluid, or a warning light. Our diagnostic checks gears, fluid, seals and electronics so you know exactly what is going on.
How long does a transmission replacement take?
It depends on your vehicle and whether we are repairing, rebuilding or replacing. Some repairs are completed in a day, while a full replacement or rebuild may take longer. We give you a realistic estimate up front and keep you updated.
