YOU HAVE TO GO THIS PLACE FOR YOUR TRANSMISSION AND YOU ARE CRAZY IF YOU DON'T!!!!! Our car felt like the gears were slipping. My husband called the shop to set up a time and Tim stated to bring the car to the shop any time and it would take about 15 minutes, but the busy times are early morning and around noon time. My husband brought the car to Tim's shop the very next day, after their lunch break. My husband was greeted immediately and Tim was very courteous and friendly. Within 10 minutes, we were told immediately it was not the transmission. We were told it was probably spark plugs or coils which causes an engine misfire and vibration. Tim was HONEST, FRIENDLY, COURTEOUS and he did all this for us at no charge. We left the shop and replaced the coil pack in the car and now the car runs super smooth. The coil pack was $90.00. Tim SAVED US FROM THOUSANDS OF DOLLARS! If you want HONEST, friendly, courteous service, THIS IS THE PLACE TO GO!!!!! THEY CARE ABOUT YOU AND THEY KNOW WHAT THEY ARE DOING!
