Transmission & Drivetrain
Prevent Transmission & Clutch Failures Before They Take Your Truck Off the Road
Your transmission and drivetrain are critical to keeping your diesel truck moving. Low fluid, worn-out clutches, or failing flywheels can cause slipping gears, rough shifting, and costly breakdowns.
O & O provides on-site transmission and drivetrain services, helping Isuzu, Mitsubishi Fuso, Hino, UD (Nissan Diesel), and GMC truck owners avoid expensive failures and ensure smooth operation.






Transmission Problems
Don't fix themselves.
Neglecting transmission or clutch maintenance can lead to:
- Slipping gears and poor power transfer
- Overheating and internal component wear
- Expensive transmission rebuilds or replacements
- Breakdowns that leave your truck stranded
Routine maintenance saves thousands in costly repairs.
