Rated 4.9 by local drivers
"Dealer quoted me $5,400 for a new transmission. G3 rebuilt mine for less than half and it shifts like new. Straight answers, no upsell."
"My truck was slipping on the highway. They diagnosed it the same morning and had me back on the road in two days. Honest shop."
"Called at 8am, towed in by 10, full estimate with photos by noon. Best communication I've had from any repair shop."
