Truck Gearbox Repair & Replacement

When your truck's transmission starts giving you trouble, every mile becomes a struggle. At West Coast Truck Repair, we've seen it all - from grinding gears to complete transmission failures that leave drivers stranded on I-5. Our team specializes in getting commercial trucks back on the road with expert gearbox repair and replacement services.

Signs Your Truck Transmission Needs Attention

Your truck talks to you - you just need to listen. Here's what it's saying when the transmission's in trouble:

• Grinding or shaking when shifting gears
• Delayed engagement when putting the truck in drive or reverse
• Burning smell coming from under the truck
• Transmission fluid leaks (that red puddle isn't good news)
• Strange noises when in neutral
• Dashboard warning lights

One driver came to us after ignoring a small leak for weeks. By the time he pulled into our Auburn shop, his transmission was severely damaged. What could have been a simple repair turned into a complete replacement - and a much bigger hit to his wallet.

Our Gearbox Repair Process

We don't just fix transmissions; we solve problems. Our approach includes:

1. Comprehensive Diagnostics: Using advanced computer diagnostics and good old-fashioned expertise to identify the exact issue
2. Transparent Assessment: We'll show you what's wrong and explain your options in plain English
3. Quality Repairs: Whether it's replacing worn synchronizers, repairing the clutch system, or addressing hydraulic problems
4. Thorough Testing: Every repair is road-tested before we consider the job done

When Replacement Makes More Sense

Sometimes fixing isn't the best option. We'll recommend replacement when:

• Repair costs exceed 50% of replacement value
• The transmission has extensive internal damage
• Your truck has high mileage and multiple transmission issues
• You need the most reliable solution to minimize future downtime

We stock remanufactured transmissions for most major truck brands and can source factory-new units when needed.

Transmission Maintenance Tips

The best repair is the one you never need. Here's how to extend your transmission's life:

• Check transmission fluid regularly (when the engine's warm)
• Don't ignore small leaks - they become big problems
• Allow your truck to warm up properly before driving
• Use the correct grade of transmission fluid
• Don't overload your truck beyond its rated capacity
