Dodge RAM Cummins Diesel Repair North Texas
Is your Cummins diesel truck blowing black smoke, losing turbo boost, or throwing emissions codes? We’ve mastered the legendary Cummins engine – from the bulletproof 5.9L to the high-tech 6.7L.
North Texas’s Cummins Diesel Authority
When Dodge partnered with Cummins in 1989, they created a diesel legend that still dominates North Texas highways today. At Paradise-Performance, we understand the unique engineering that makes your RAM Cummins diesel different from every other truck on the road. Unlike generic repair shops that treat all diesels the same, we specialize in the specific needs of Cummins-powered trucks.
Our Cummins repair specialists in Paradise, TX have diagnosed and repaired hundreds of Cummins diesels across all generations. From the rock-solid 12-valve 5.9L that can run forever with proper maintenance to the sophisticated 6.7L with its advanced emissions systems, we speak fluent Cummins. That expertise has earned us a 5.037-star Google rating from satisfied customers throughout the Dallas-Fort Worth area.
Complete Cummins Generation Expertise
12-Valve 5.9L Cummins (1994-1998)
The mechanical legend that needs no computer to run. We handle injection pump rebuilds, valve adjustments, and the legendary reliability maintenance these engines deserve.
24-Valve 5.9L Cummins (1998.5-2007)
Electronic fuel management with legendary durability. Our specialists excel at VP44 and CP3 injection pump repairs, lift pump failures, and performance modifications.
6.7L Cummins (2007.5-Present)
Modern emissions with classic Cummins strength. We handle DPF regeneration issues, DEF system repairs, turbocharger maintenance, and complex ECM diagnostics.
Just last week, we saved a construction company owner from a $8,000 dealer estimate on his 2019 RAM 3500. The truck was in limp mode with multiple emissions codes. Our diagnostic revealed a faulty NOx sensor and clogged DPF – a $1,200 repair that had the truck back to full power the same day. Experience matters when your livelihood depends on your truck.

Why Paradise-Performance Dominates Cummins Repair
When choosing a Cummins repair shop in North Texas, the differences become obvious quickly. Dealerships often lack the deep Cummins knowledge that comes from years of specialized experience, and they charge premium prices for routine services. Chain shops focus on quick turnaround rather than quality repairs, leading to comebacks and frustrated customers.
At Paradise-Performance, we’ve built our reputation on understanding what makes Cummins engines special. Our technicians regularly attend Cummins training, we maintain relationships with specialty parts suppliers, and we invest in Cummins-specific diagnostic equipment. This translates to faster diagnosis, more accurate repairs, and better value for our customers.
We also understand that Cummins owners are different. You chose your truck because you need reliability, durability, and capability. That’s why we offer transparent pricing, detailed explanations of repairs, and maintenance plans designed to keep your Cummins running for 300,000 miles or more. Our fleet truck service accommodates commercial customers with priority scheduling and volume pricing.

Common Cummins Problems We Solve Daily
Every Cummins generation has its unique challenges. Our decades of experience mean we can quickly identify and resolve these common issues before they become expensive failures:
Lift Pump Failures
Especially common on 1998.5-2007 trucks. We diagnose fuel starvation issues and install quality lift pump upgrades that prevent VP44 and CP3 damage.
VP44 Injection Pump Issues
The Achilles heel of 1998.5-2002 24-valve engines. We handle rebuilds, replacements, and the fuel system upgrades that prevent premature failure.
Grid Heater Problems
Failed grid heaters can damage intake manifolds. We repair and upgrade to aftermarket solutions that eliminate this common failure point.
Death Wobble & Steering Issues
Heavy diesel trucks stress steering components. We diagnose and repair track bars, ball joints, and steering dampers with quality parts.
Transmission Overheating
68RFE and Aisin transmissions need proper cooling. We install auxiliary coolers and perform transmission services that extend life.
Exhaust Brake Malfunctions
Essential for safe towing. We repair and maintain exhaust brake systems to keep your heavy loads under control.
