We had an older 1994 Dodge Ram Diesel 3/4t with transmission troubles. The “price was right” for repairs. The experts knew to troubleshoot if underlying problems were present. The repairs were fast. Warranty work for a new faulty transmission was done ASAP. After a year, the underlying problem was the throttle positioning sensor and the transmission speed sensor. Both were replaced and the transmission operates like new. It was well worth the time and money to have Pro-Tech experts involved where others would have told us to buy a new vehicle!!! Thanks to Rob and his team, all the highest praise and respect.
