Very few automotive mechanics earn my trust. These guys are top notch and honest. No charge for today's work because it wasn't a transmission problem. Anyone else would have at least charged me an inspection fee of some kind. Jeremy comes from Hill Automotive which is the only other mechanic I trust.

I purchased a used GMC Jimmy with 4WD in 2008. I never used the 4WD until I found myself in a foot and a half deep mud on the side of the highway while making a u-turn in 2013. The 4WD worked and got me out, but I started noticing a grinding sound coming from under my seat even though I ran it only a short distance. Clay County Transmission was recommended for the diagnostic and any work I might need done. They diagnosed that the gears in the transfer case were sheered and investigated further to determine why it was destroyed. As it turned out the previous owner swapped out the gearing in the rear of the vehicle without matching the gearing for the front end. In other words the front and back were spinning at two different speeds causing the weaker point to break... The gears in the transfer case. They rebuilt the transfer case matching the gearing for the rear axel so it wouldn't tear up again. They also removed my transmission and performed a complete service on it by disassembling and inspecting every part for wear and cracks and replacing the seals. It's now 2016 and I still have had no issues with it, despite hauling trailers and towing a boat on occasion. I would strongly recommend using Clay County Transmission because of the way they conduct their business. They actually do a FULL inspection and diagnostic to determine, not only the part that needs repair, but the cause of the failure. They don't "PAD" the bill charging for time not spent on the job merely because the MAC chart says they can. I can't express enough how professional they were, when conducting their services... They make recommendations based on facts, not assumptions or guesses like other shops I've used in the past.

Extremely efficient and great service! Rick was great and my car was ready in less than a day from dropping it off! Highly recommend.
