Testimonials

On 12/6/2025 Nick Cali had this to say:
If you’re looking for real people like you and I to diagnose a transmission problem, Dr Steve’s is the place to go. Met with Russ today and he explained his findings in live time as he drove my truck. He had the power to just book me for a new transmission, but his honesty directed me to get something extremely minor fixed first. After an hour of driving and chatting about the issue at hand, he didn’t charge a dime. Couldn’t recommend them enough.
