Q. Is flushing your transmission good for it?


A. Yes, if done properly.  Flushing your transmission removes harmful material from the system and replaces broken down fluid; however, doing only a flush can leave harmful material in the sump, which can be pulled into the filter restricting vital lube causing extreme damage to your transmission.  We will completely flush the system with the proper fluid, remove the fluid pan, replace the filter (if applicable), clean fluid pan, replace fluid pan gasket, and make all applicable adjustments.  We recommend that you flush your transmission every third time your transmission is serviced.  


Q. When should I service my transmission?


A. Highway driven vehicle:  24 months or 24,000 miles

Stop and go traffic:  12 months or 12,000 miles

This is the life of your transmission!


Q. Do you have to take my transmission apart to see what’s wrong with it?


A. In most cases NO!  Most transmission related problems can be repaired while the transmission is still in the vehicle.  Automatic transmissions with internal problems can be diagnosed in the vehicle and we can give you a fair, honest, firm price for repairs before any work begins.  Most of the time, standard shift transmissions and transfer case problems require disassembly of the unit before a price can be given.  An estimate is provided before any work begins and we come extremely close to the estimated price




A. We ask that customers leave their vehicles with us as early in the day as possible so that we have time to properly diagnose the problem and get back to you by noon with a firm price to fix your vehicle. This is a FREE service.


Q. How long will it take to check my transmission?


I brought my car to Cobra Transmissions after a national chain repair shop in Lexington, KY failed twice to repair the transmission on my automobile.  Randy and his technicians were professional, friendly and performed quality work.  Four years later, I have not had a single transmission problem.  I would recommend Cobra Transmissions to anyone that needs a transmission repair.

I was referred to Cobra transmission by an auto mechanic in my church who had them fix his tranny while he was sick. The first time we visited them was for a second opinion. We'd been given a $600 estimate by another repair shop that was in Richmond. Within a day we had our estimate from Cobra--about $75. That repair lasted us for six years. We put a lot of miles on our car. My husband used to drive from Irvine to Richmond and now drives from Winchester to Richmond daily for work. In addition to that we make trips between 500 and 800 miles a few times each year, and weekly trips to Lexington. Any six year repair job thrills us, let me tell you.My mother had to buy a rebuilt transmission from them four years ago. Cobra again had the best price of anyplace in the region, and although it only came with a thirty day warranty, it's still going strong and she puts as many miles on her car as we do ours. We recently had them fix our van, and once again we were impressed with their professionalism, their ability to come in on or under estimate, and their speed of work.

Dependable, trustworthy service

Randy, Thanks. The rear differential on my 2004 Explorer was leaking and had a grinding noise. After you fixed it, you said it would be like a new car, and you were Correct. It was a huge difference. Thanks for the good work. Always heard you were dependable and honest, and I believe it….


Thanks again.

I would like to take a moment to say Thanks to Randy Charles and his crew. Great place to take your vehicle for repair. I am a person who travels all around the country. I went in with a concern for my transmission which I overheated. They inspected it flushed it and adjusted the bands. It works great didn’t over charge me , very honest, and good to do business with. Thanks again for your help.

I brought my van to Cobra for a transmission issue. The part they originally put in my car to fix the issue didn't work properly after a few weeks. As a result they went above and beyond to fix it without question. The staff- especially the owner of Cobra is very honest and reliable. I completely trust what they do and I was very impressed with how they were committed to my satisfaction- no matter what. I have had no issues with my van since the work they did on it and I am very thankful for them taking the initiative and going above and beyond to fix my car. I have already recommended Cobra Transmission to several people I know. Thank you! KN.
