Engine Rebuilds Backed
by a 3-Year Warranty

One of our core specialties is engine rebuilding. When your engine is showing signs of wear, poor performance, or catastrophic failure, replacing it with a new one can be incredibly costly. That’s where an engine rebuild from All in One Auto Repair comes in as a smart and cost-effective solution.


Our engine rebuild process is detailed, precise, and performed with the highest standards of workmanship. We carefully disassemble the engine, inspect each part, and replace or machine components as necessary to restore it to peak condition.

Engine Rebuild Process

Inspection
Complete engine disassembly and thorough inspection.
Cleaning
Cleaning of all parts using advanced techniques.
Replacement
Replacement of worn components (bearings, seals, pistons, gaskets, etc.).
Precision

Reassembly

Transmission Rebuilds

Your vehicle’s transmission is one of the most critical and complex systems, responsible for transferring power from the engine to the wheels. When it starts to fail, you may notice slipping gears, grinding noises, delayed shifting, or complete loss of drive. By choosing a rebuild instead of replacement, you save significantly on cost while restoring your transmission to like-new condition. Our technicians ensure that your rebuilt transmission performs reliably, giving your vehicle a new lease on life.
