Our Allison transmission experts handle clutch replacements, transmission rebuilds, and shifter linkage repairs. We offer SCR/DPF diagnostics, DEF injector replacements, and limp mode fixes to restore power.

Freightliner Brake & Air System Repairs
We specialize in ABS valve block replacements, air brake diagnostics, and compressor rebuilds. Our hydraulic brake service includes rotor and pad replacements, plus leak detection from heat-stressed systems.
Cooling & Fuel System Repairs
Arizona’s heat is tough on trucks, so we provide radiator flushes, cooling system repairs, and desert-grade coolant replacements. Our fuel injector cleaning service ensures better mileage and engine efficiency.
Suspension & Steering Repairs
For Freightliner suspension systems, we replace leaf springs, airbags, and shocks to improve ride quality. We also handle power steering gearbox rebuilds and tie rod replacements for precise handling.

We perform complete HVAC system overhauls. Need frame welding? We fix corrosion, collision damage, and crossmember reinforcements.

Frequently Asked Questions
What If My Peterbilt Over Heats in Tucson’s Heat?
Overheating is common in Tucson’s heat. We offer radiator upgrades, coolant flushes and desert grade lubrication to keep your engine cool in 110°F+ temps.
Do You Do Peterbilt Transmission and Clutch Repairs On-Site?
Yes, we repair Eaton Fuller and automated transmissions, replace clutches and do full system diagnostics. Shifting problems, fluid leaks, gear repairs? We do it all without towing.
How Often Should I Service My Freightliner Truck?
Regular maintenance is key to avoiding breakdowns. Oil changes, fluid checks and brake inspections every 10,000-15,000 miles and a full inspection every 50,000 miles.
Why Is My Freightliner Losing Power?
Loss of power could mean clogged fuel filters, turbocharger issues or a failing EGR system. We can diagnose the issue on site and get you back to full power.
How Do I Schedule a Freightliner Repair in Tucson?
Call our 24/7 service line. We do same day mobile repairs so you don’t have to tow your truck to a shop, our techs come to you!
What Do I Do if My Freightliner’s Check Engine Light Comes On?
If the check engine light comes on, stop and have a scan done. Ignoring it can cause major engine damage especially if it’s related to emissions, fuel injection or turbocharger performance.
How Do I Prevent Freightliner DPF and DEF System Failures?
Regular maintenance is key. DPF filters need to be cleaned every 200,000 miles and DEF fluid levels need to be checked regularly. We offer on site DPF cleaning, regen services and aftertreatment system diagnostics to prevent downtime.
What Are Signs of Brake Issues in A Freightliner Truck?
If you experience soft brake pedals, delayed stopping or air leaks in the brake system, service is needed ASAP. Freightliner air brakes need regular maintenance to ensure safe stopping power especially in Arizona’s extreme conditions.
