Their expertise is highly sought after by diesel enthusiasts and truck owners seeking reliable and accurate solutions for complex issues.
---While the provided reviews do not offer a direct visual description of the physical shop environment, the testimonials strongly convey an environment rooted in deep technical expertise and efficient, professional communication. The fact that customers "contacted them via email and they answered all my questions fast and accurate" suggests a well-organized administrative and technical support system, indicative of a professional operation. The personalized advice and detailed explanations given to customers, even remotely, imply a focus on education and empowerment, creating an environment of trust and transparency.

---Kennedy Diesel, as its name suggests, is a specialized "Auto Repair Station" with a primary focus on diesel engines. Their services extend beyond basic repairs to include highly technical aspects of diesel performance and longevity:
- Advanced Diesel Diagnostics and Repair: They specialize in identifying and resolving complex diesel engine issues. This includes addressing problems like "EGR issues," "shifting issues," and "low fuel rail pressure codes." Their ability to accurately diagnose and recommend precise solutions, such as a "new TCM" or specific types of injectors, is a core offering.
- Engine Tuning and Performance Optimization: A significant service is their expertise in "tuning to my rig to help achieve the Duramax's full power without abusing my rig." This involves optimizing engine parameters for performance and efficiency while ensuring the longevity of the vehicle, contrasting with less reputable "expensive plugins." This high-level service requires deep understanding of diesel engine mechanics and software.
- Parts Sales and Recommendations: Kennedy Diesel provides and recommends high-quality diesel parts. This includes components like Transmission Control Modules (TCMs), injectors (with a strong preference for brands like Bosch over aftermarket alternatives), and CP3 fuel pumps. They are a trusted source for genuine and reliable parts, which is crucial for diesel longevity.
- Expert Technical Advice and Consulting: Customers frequently "emailed John for advice" on complex issues, indicating that Kennedy Diesel offers a valuable consulting service. This involves providing accurate information and guidance on troubleshooting, repair strategies, and even advice on avoiding common pitfalls (e.g., problematic aftermarket injectors). This advisory role extends their service beyond just physical repairs.
- Remote Support: Their ability to effectively assist customers via email, even those far away ("trip back to Florida"), highlights a strong remote support capability, making their expertise accessible to a wider geographic area.
This range of specialized services positions Kennedy Diesel as a comprehensive and expert resource for diesel vehicle owners, particularly those with Duramax models, offering everything from diagnostics to parts and performance tuning.

- Deep Diesel Specialization: Their singular focus on diesel engines, particularly Duramax, allows for unparalleled expertise in diagnosing and resolving complex issues specific to these powertrains. This depth of knowledge is a significant competitive advantage over general auto repair shops.
- Highly Accurate Diagnostics and Solutions: Customers praise their ability to provide "accurate" answers and effective solutions for persistent problems, such as recommending a TCM that immediately fixed a shifting issue or correctly identifying injector problems.
- Commitment to Quality Parts: Their strong stance against problematic "aftermarket injectors" and preference for reliable components like "Bosch injectors" underscores their commitment to using and recommending only high-quality parts that ensure lasting repairs and optimal performance. They are not just selling parts but ensuring the right parts are used for the job.
- Expert Performance Tuning with Integrity: Unlike companies that sell "expensive plugins that cause issues," Kennedy Diesel offers tuning solutions that "help achieve the Duramax's full power without abusing my rig." This ethical approach to performance enhancement prioritizes engine health and longevity, a critical differentiator.
- Exceptional Customer Education and Support: The willingness to "answer all my questions fast and accurate" and provide detailed "advice" via email demonstrates a strong commitment to customer education and support, empowering vehicle owners to make informed decisions.
- Reliability and Trust: Consistent positive experiences and strong recommendations ("I will keep using Kennedy diesel and recommend them to anyone wanting quality advice with excellent service") highlight the high level of trust customers place in their expertise and integrity, even for significant issues like engine components.
The promotional message for Kennedy Diesel within the "Auto Repair Stations" category is exceptionally strong, driven by detailed and highly positive customer testimonials. These reviews serve as powerful endorsements for their specialized services:
- Evidence of Problem-Solving Expertise: The first review details their success in resolving challenging "EGR issues" and "shifting issues," directly showcasing their diagnostic and repair capabilities. This is particularly appealing to customers facing persistent or complex problems.
- Value of Expert Advice and Remote Support: The fact that they provide "fast and accurate" answers via email, even leading to successful self-repairs (like the TCM replacement), highlights their valuable advisory role and ability to support customers remotely. This expands their service reach far beyond their physical location.
- Commitment to Ethical Performance Tuning: Their approach to "tuning to my rig to help achieve the Duramax's full power without abusing my rig" is a key promotional point. It positions them as a responsible and knowledgeable provider of performance upgrades, appealing to customers who want power without compromising vehicle integrity.
- Authority on Parts Quality: The second review's extensive discussion about problematic aftermarket injectors versus reliable Bosch parts, directly correlating with "John Kennedy's" advice, establishes Kennedy Diesel as an authority on quality diesel components. This builds confidence in their recommendations and parts sales.
- Building Long-Term Relationships: The statements "I will keep using Kennedy diesel" and "if I didn’t have a quality diesel shop close to me I would have ordered my injectors and cp3 from Kennedy Diesel" underscore their ability to foster loyalty and earn consistent business, even when customers have other local options.
In conclusion, Kennedy Diesel's promotional strength lies in its demonstrated expertise, ethical approach to performance, commitment to quality parts, and exceptional customer education and support.

Kennedy Diesel Customer Reviews
I was having EGR issues with my 2006 Duramax and they helped me achieve the the outcome I was needing. I now have a 2010 Duramax and was having shifting issues and I contacted them via email and they answered all my questions fast and accurate. They recommended a new TCM and once received I threw it in and took care of my issue. They are helping with some tuning to my rig to help achieve the Duramax's full power without abusing my rig like all the company's that sell expensive plugins that cause issues over addressing power needs the correct way. I will keep using Kennedy diesel and recommend them to anyone wanting quality advice with excellent service.

I have an 08 duramax, was have trouble with low fuel rail pressure code, listen to what he has to say about after market injectors, I was out of town when I put in first bank of injectors, didn’t know of any local diesel shops or of Kennedy diesel at that time, purchased them from nationwide parts store. Got home went to same parts store change and purchased the other bank of injectors, still had trouble with code, so I opted to replace CP3 purchased that from a local diesel shop in my area, which is a great quality shop also, had them check my old one they confirmed it was bad, but after installing I still had same issue, pulled all injectors out and took them to the diesel shop, they checked them for me, 3 where over fueling, 2 where leaking, 1 was under fueling, replaced them with Bosch injectors, problem solved, this diesel shop says the same thing as John Kennedy does about aftermarket injectors. I have personally emailed John for advice and have ordered tools and parts from them, everything has been spot on with them, if I didn’t have a quality diesel shop close to me I would have ordered my injectors and cp3 from Kennedy Diesel.

Beware of this company. I bought an extreme duty fan clutch for my Duramax and after installing it I drove 8 miles and wasn’t watching my temps because I hadn’t even got out of town or hit any hills yet and my engine overheating warning flashed in front of my eyes. Truck says idle engine to cool down so I pulled over immediately and truck got up to 270 degrees. I installed my stock fan clutch on the side of the road and the truck was running at normal temperatures again as it always did. 18 hours into my drive my piston broke in half and I strongly believe it is due to the engine over heating so badly from this faulty item. Kennedy refuses to give me a refund, they want to send me another clutch. My engine only had 23000 miles on it and now I’m spending $13000 for another engine Andy business cannot be without a truck for the month it’s taking to fix the truck so I had to buy another truck. I was stuck in another state with a broken truck and 40ft trailer. Took me 3 days to drive home get another truck and trailer and pull the broken stuff back. It’s been a nightmare and this company is more concerned with the $139 then anything... unbelievable junk and horrible customer service.

I have a 2006 Duramax LBZ. Had trouble with it going into limp mode while towing anything with the dreaded 0087 low fuel rail pressure code. I stumbled across Kennedy diesel on forums and this guy was a life saver. He explained everything to me and I bought a new computer for my truck. Not even 10 minutes to change the part. That was 4 years ago and still no issues. If you have a low fuel rail pressure code do yourself a favor and just contact him right away before you try to throw a lot of time and money at it. He knows what he is talking about.

Had one of their twin lift pumps installed on my truck, followed directions to a t and within 3000 miles and 8 months the wiring harness corroded and fell apart when I unplugged it. I live in and extremely dry environment with no road salt. I called them and they said it's on me to replace the harness. I'm very upset with their customer service on a $600 part. This will be the last time I purchase anything or recommend them for any service.
