A look at the front of Delta Transmission’s Antioch facility

Delta Transmission has been servicing, repairing, replacing and rebuilding transmissions at its Antioch facility since 1958. In addition to general transmission work, the company handles brake repairs and replacements for most vehicle makes and models. It also offers free diagnoses on transmissions and differentials, and it can take care of insurance paperwork for clients.

Owner Chester Kniss is a veteran of the automotive industry whose fascination with cars began when he was a child. Mr. Kniss says he prides himself on honoring his quotes. “Once I conduct a thorough transmission diagnosis, the price I quote is the price the customer pays. Even if I discover problems later that add to the scope of the work, I won’t adjust my quote upward.”

Delta Transmission has remained small and family- owned throughout its history, and it continually contributes to its community through student athlete sponsorship programs. Mr. Kniss says the company’s core values have always remained the same: to provide honest, professional service at a fair price. “We’re never too busy to answer questions or explain procedures. We enjoy sharing our knowledge and educating our clients about their transmissions.”

“As lifelong residents of this area, we’ve developed deep connections with our customers and community. We consider our clients parts of our extended family and treat them accordingly. We’re devoted to providing a welcoming environment where people can receive expert, reliable transmission work.”

Choose a transmission repair shop willing to stand behind its estimates.
Many shops offer low estimates to win your business. But once they actually have your vehicle in the shop, the price suddenly rises and you have little recourse—at least not when your transmission is lying in pieces on the shop floor.

Of course, you can’t always know in advance which shops are honest and trustworthy, but you can do some homework. Start with friends and family members. Even better, drop into a few local auto parts stores and ask about the reputation of local repair shops. Since the employees of auto parts stores are often automobile aficionados, their opinions can be extremely valuable.

The most reliable transmission shops are the ones willing to stand solidly behind their work. Never shop by price alone. With an expensive transmission repair, the warranty is a much more important consideration than the price. You don’t want to save money at a cut-rate transmission shop only to discover you need to repair the transmission again down the road. It’s better to pay more for a rock-solid warranty and the peace of mind that goes with it.

Consider using shops that have good ratings from the Better Business Bureau, with no unresolved complaints or serious problems with past customers. Ratings services like Diamond Certified can also steer you toward reputable shops with a strong track record of reliable service.

If you look, you can probably find a transmission shop that’s been around since before you were born. Take that as a sign. These shops typically owe their longevity to a hard-won reputation for good work, fair dealings and reasonable prices.

In business for more than half a century, Delta Transmission and Engine specializes in transmission service, repair and custom rebuilds. It offers a full range of services, from transmission servicing to complete replacement. The company also handles brake work on most vehicle makes and models.

Owner Chester Kniss considers his customers family and treats them as such–"with honest, professional service at a fair price," he says.

For one, that means honoring his quotes. Once Mr. Kniss conducts his thorough diagnosis of your engine or transmission, the price he quotes is the price you pay. Even if he later discovers problems that add to the scope of the work, he won't adjust his quote upward, which is a common practice in the industry. He'll sooner take a loss on the job. Similarly, Delta honors its warranties without question or complaint.

The company never takes its customers for granted, says Mr. Kniss. He's happy to explain the work being performed on your car, lay out your options and give you an honest and objective opinion. He never recommends work that isn't necessary and willingly advises you on ways to save money and extend the life of your car.

As a small and family-owned business, Delta is proud of its ties to the community. It sponsors student athletes through two area high schools, as well as a local race track.

Chester Kniss: A Mechanical Mind

By James Florence, Diamond Certified Resource Reporter

ANTIOCH — When asked how he got involved in the auto repair field, Chester Kniss simply replies that he’s always been mechanically minded. “I’ve been interested in cars since I was a little boy, so I picked things up pretty naturally,” he says. “At 10 years old, I was able to accurately diagnose car problems, and by age 15, I’d built my first transmission.” After high school, Chester went directly into the automotive industry, where he s...

First off, I would tell people that they can trust this shop. I know that there is a lot of speculation now days with shops, as some are dependable and others are not. It is hard to tell. I think that this shop is very honest in the way they conduct their services. If they cant fix it, they won't, or if they think that it is not beneficial for you in any way, they will tell you.

I felt like I could trust them.

I tell them that first of all, they have been in business for a long time and you don't stay in business that long by doing stuff wrong, which is why I chose to do business with them. They were like family, very informative and very nice and I couldn't have gone to a better place.

The information that they gave me about my transmission as it was making noise and they told me that there were metal shavings in it and he couldn't tell me how long it would last, which is information that I greatly appreciated.

I think Chester is a pretty good mechanic. He was able to figure out why the transmission kept slipping and literally only needed a few hundred dollars to repair it. I thought it was going to cost a few thousand, so I was very satisfied with them.

I needed some rings replaced in the transmission. Chester was able to offer us a really reasonable price. The estimated time it would take was good, and they seemed professional and knowledgeable about what they were talking about.

I didn't feel like they were trying to upsell me on anything. I went to another shop, and they quoted me $3,000 dollars, saying that I needed a whole new transmission put in. I took it to Delta, and they resolved the problem for less than $500.
