Hy-Tech Transmissions 803 U.S. 40, Greenville, IL 62246

"Great place. This is my second transmission on two different Chevy trucks that they have repaired. I didn't want to do just an OEM repair. Hytech upgraded my transmission, and it is running great. Wish they would open another office in St Louis."

"It is a relief to know genuine, knowledgable, helpful mechanics still exist...after a road-side transmission failure ruined our trip to Florida, Ryan and everyone at Hy-Tech did everything possible to get us back on the road safely and swiftly. Now we are back driving south and my transmission is running better than when I bought the car! Im looking forward to saving a ton on gas and truckin’ with ease now thanks to this great shop. Highly recommend to anyone with transmission issues, or otherwise."

"Recommended to me by my brother and his friends. 4L80 in my Yukon bit the Dust.They are proud of what they. Price was where it should've been for the quality of work. They did not disappoint. Was done in a timely fashion. Rides like a dream! Would definitely recommend if you need your Chevy/GMC worked on."

"I had dropped off my transmission at a shop about 5 minutes from my house. They had it for 6 weeks and all it did was sit on the shelf. That’s when I asked a mechanic on recommendations for transmission shops in the area. He told my go to Hy-Tech in Greenville. Fast professional at a great price. Anyone thinking about getting transmission work done, this is your place."

"Had a pretty bad experience with this place. My fiancee and I brought both of our cars up to fix the transmissions. The guy said he diagnosed my car but all he did was drive it around and waste my gas. I got no diagnosis but I got charged $50. Then we paid $3400 to fix my finances transmission. 2 months later one of the lines started leaking and I had to fix it myself because when I called nobody returned my phone call. Very unsatisfied"
