Avoid the High Cost of Transmission Failure.
Your transmission is the heart of your vehicle’s drivetrain. When it starts slipping, overheating, or shifting hard, your entire operation is at risk. Ignoring a small transmission glitch today almost always leads to a catastrophic (and expensive) failure tomorrow.
OKC Fleet Services specializes in both automatic and manual transmissions for commercial trucks, RVs, and fleet vehicles. We use advanced diagnostic software to communicate with the Transmission Control Module (TCM), identifying whether your issue is a simple sensor failure, a fluid problem, or internal mechanical wear.

Full-Spectrum Transmission Service Solutions
We provide complete care for manual, automatic, and automated manual (AMT) transmissions, including diagnostics, maintenance, repairs, and full rebuild services. Our technicians ensure smooth shifting performance, improved reliability, and extended transmission lifespan for a wide range of heavy-duty and fleet vehicles.
Transmission Diagnostics
We use bi-directional scan tools to monitor gear commanded vs. gear attained, fluid temperature, and pressure sensor data to find the exact cause of the fault.
Fluid & Filter Exchange
Extend the life of your transmission with high-quality synthetic fluids and OEM filters. We remove contaminants that cause friction and overheating.
Clutch Repair & Replacement
For manual and AMT systems, we provide expert clutch adjustments, resurfacing, and full replacements to ensure smooth engagement.
TCM Programming & Repair
Many modern “transmission” problems are actually computer issues. We flash and program Transmission Control Modules to solve shifting glitches.
Driveline & U-Joint Service
We inspect and repair the entire power transfer system, including driveshafts, U-joints, and carrier bearings, to eliminate vibrations.
Seal & Gasket Replacement
Stopping leaks before they lead to low fluid levels and internal burnout. We handle main seals, pan gaskets, and output shaft seals.
Transmission Rebuilds
When repair isn’t enough, we offer complete rebuild services using heavy-duty components designed to outlast factory specs.
Complete Replacements
We source and install high-quality remanufactured or new transmissions to get your vehicle back in service with a full warranty.
The OKC Fleet
Transmission Process
Electronic Analysis
We scan for codes and monitor live data during a test drive to see how the transmission behaves under load.
Fluid Inspection
We check the color, smell, and debris levels in your fluid. This “liquid history” tells us exactly what’s happening inside the gears.
Mechanical Evaluation
We inspect external linkages, mounts, and cooling lines to rule out simple fixes before recommending internal work.
Transparent Estimate
You get a clear breakdown: Is it a solenoid, a sensor, or a mechanical failure? We show you the data so you can make the right call.
Precision Repair & Road Test
After the work is done, we perform a rigorous road test to ensure every shift point is perfect and temperatures are stable.
