Commercial Fleet Services
Commercial fleet vehicles often face heavy use, frequent driving, towing, and demanding operating conditions. Over time, this can lead to transmission, clutch, differential, gear, and drivetrain problems. Identifying warning signs early can help reduce unexpected breakdowns and costly downtime.
Common Issues Include:
Transmission Problems – Slipping, hard shifting, delayed engagement, and unusual noises can indicate transmission wear or damage.
Clutch Wear – Frequent stop-and-go driving and heavy loads can accelerate clutch wear, causing slipping or difficulty shifting.
Differential Problems – Whining, grinding, vibration, or leaks may indicate worn differential gears, bearings, or other components.
Gear Damage – Worn or damaged gears can cause grinding, noise, difficulty shifting, and reduced drivetrain performance.
Drivetrain Vibration – Excessive vibration may be caused by worn or damaged drivetrain components.
Fluid Leaks – Transmission or differential fluid leaks can contribute to premature component wear and serious mechanical problems.
Excessive Noise – Humming, whining, grinding, or clunking sounds can be early indicators of drivetrain problems.
Unexpected Downtime – Mechanical failures can take commercial vehicles out of service and interfere with daily fleet operations.
Regular commercial fleet maintenance and drivetrain inspections can help identify developing problems before they result in more extensive repairs.

Signs of Transmission & Clutch Issues
Knowing the signs of transmission and clutch failure can save you from costly repairs and downtime.
- Experiencing slipping gears
- Delayed engagement
- Grinding or shaking while shifting gears
- Strange noises
- A burning smell
It’s essential you get these symptoms addressed, a broken transmission will cause you a whole world of problems that you don’t want to deal with.
Scheduled Maintenance Services:
It is a service designed to replace virtually all of the old, degraded transmission fluid with fresh fluid to help prolong the life of your transmission. It is much more than just a simple fluid drain from the transmission pan; we will check and then exchange virtually all of the old fluid from your transmission system with new fluid.
Fluid Level Check & Fluid Replacement :
We will check your fluid levels. Low fluid levels can lead to little lubrication of transmission parts, which speeds up wear and tear and leads to problems.
Fluid replacement should be done every 30,000 miles to promote proper vehicle operation. We’ll change your filter and replace the old fluid with fresh, new fluid. We’ll also clean your pan and replace the old pan gasket.
Tranny Flush:
Approximately every 30,000 miles, fluid begins to break down and loses its effectiveness. That leads to build-up and deposits, which can hasten the erosion of your transmission’s internal parts. Regular performing a tranny flush removes that debris and keeps your transmission clean. That will increase the life and performance of your transmission.
Differential Services
Fluid Replacement:
Regular fluid changes are essential for maintaining optimal differential performance. Our team handles fluid replacements, ensuring proper lubrication and preventing premature wear.
Ring and Pinion Gear Inspection:
The ring and pinion gears are critical components of the differential. We conduct thorough inspections, addressing wear and misalignment and ensuring proper meshing for efficient power transfer.
Seal Replacements:
Leaking seals can lead to fluid loss and potential damage. We specialize in seal replacements, preventing contamination, and maintaining a sealed, lubricated environment within the differential.
Complete Overhauls:
For extensive issues, our comprehensive differential overhauls cover bearing replacements, gear adjustments, and ensuring all components meet manufacturer specifications.
