After getting quotes from the Hyundai dealers for $349 and $159 just to change the transmission fluids before a road trip, I remembered this little shop. I called and they said bring it by the next morning and, by the way, it would cost $62.00. After dropping it off about 8:30, they called soon after noon and it was done. They were close to my house, they were fast and they were extremely affordable and very nice. Just look real hard going west past Denton Hwy and they are tucked in off to the right. You'll be glad you did.
Pros: Fast & Reasonable
Cons: Hard to find, but worth the search
