Who we are

Maximizing Driveline Power Output and Fuel Efficiency

Operating commercial trucks with misfiring engines, slipping transmissions, or severe oil leaks causes sudden highway strandings, costly cargo delays, and total powertrain destruction. Servicing engine sensors, turbochargers, and clutch linkages immediately restores horsepower, protects transmission gears, and keeps your heavy transport fleet operating reliably across long-haul freight routes.

Why You Need This Service

Stop Powertrain Oil Spills From Degrading Drive Rubber

Engine oil or transmission fluid leaking from cracked lines drips directly onto rear drive tires and brake assemblies, degrading rubber compounds and contaminating brake shoes. Oil-soaked tire rubber weakens rapidly, leading to belt separation, while contaminated brakes grab unevenly, causing sudden wheel lockups that grind flat spots into expensive tires and strain hub seals. Our mobile powertrain technicians respond quickly to fix leaking oil lines, replace failed transmission seals, and clean fluid residue on site. Stopping drivetrain fluid leaks preserves drive tire integrity, protects brake drums, and prevents severe drive axle mechanical damage on active shipping routes.

Neutralize Drivetrain Shock and Sudden Wheel Lockups

Transmission slippage or engine surging under heavy payload stress sends violent shockwaves through the driveline, causing drive tires to lose and regain traction repeatedly at highway speeds. This rapid slipping friction generates intense surface rubber heat, leading to sudden tread separation and explosive blowouts that can tear off aluminum quarter fenders and brake lines. Calling our mobile engine and transmission team at the first sign of power loss or harsh shifting ensures fast computer diagnostics, sensor replacement, and clutch adjustments. We restore smooth powertrain delivery, preventing violent drivetrain shocks that damage drive tires, destroy U-joints, or compromise vehicle control.

Advanced Diagnostic Scans, Sensor Fixes, and Clutch Tuning

Maintaining commercial powertrain performance requires combining expert engine diagnostics with complete driveline maintenance. Our mobile mechanics perform sensor replacements, fuel line repairs, and clutch adjustments directly at truck stops, fleet yards, or highway shoulders. Equipped with advanced diagnostic computers and heavy-duty mechanical tools, our service trucks resolve severe engine and transmission issues on location, eliminating costly towing fees and keeping your commercial haulers on schedule.

 Trustindex verifies that the original source of the review is Google. An absolute nightmare of a company to deal with !!! All I can say is stay clear and don’t take their word when they tell you they will show up. We literally sat on the side of interstate waiting for 6 hours for this company to show up and were told numerous times they were on the way.  We were completely lied to ! Excuse after excuse as to why they didn’t show. No communication whatsoever. Do yourself a favor and don’t waste your time with this crooked fly by night place. We were even told after the fact that Robert conducts this kind of business all the time and is not a trustworthy person.

 Trustindex verifies that the original source of the review is Google. Today, I had the privilege of meeting Robert and Angela Maclin from Emergency Response LLC. Although their base is in Williams, AZ, they were somewhat nearby. I had previously read their reviews and was quite impressed. Since they had traveled to Phoenix to deliver a load, Robert, a highly skilled mechanic, kindly offered his assistance. Robert exemplifies the true meaning of a Jack of All Trades, and along with his wife, they diligently worked until all the issues with my RV were fully resolved. Their work was carried out with great efficiency and professionalism. I would highly recommend this company to anyone in need of repairs, heavy equipment hauling, or semi-mechanic services. Thank you, Robert and Angela, for your invaluable help.

Common Questions

Most Popular Questions.

What causes an automated semi truck transmission to get stuck in neutral while driving?

Low air pressure to shift actuators, failed XY shifter motors, broken clutch actuators, or faulty gear position sensors cause shift lockouts.

Can a commercial truck clutch be adjusted on the roadside?

Yes, manual pull-type commercial clutches can be adjusted through the inspection cover using specialized tools to restore proper free-play.

Why is my diesel engine losing boost pressure under heavy acceleration?

Cracked silicone charge air hoses, loose T-bolt clamps, leaking intercoolers, or failing turbo VGT actuators cause boost loss.

How long does it take to replace a failed transmission shift actuator on location?

Our mobile technicians can typically diagnose the fault, swap the shift actuator motor, and perform a software clutch calibration in 1 to 2 hours.

Do you service both manual and automated transmissions like Eaton Fuller and Detroit DT12?

Yes, we carry diagnostic equipment and service parts for Eaton Fuller, Detroit DT12, Volvo I-Shift, and Mack mDRIVE transmissions.
