A customer’s testimonial:

Kris C. Boardman, OR - 10/19/2011

These guys are just awesome; if I buy a used car I can bet it's going to have transmission issues. 4 cars later I still recommend these guys. If something goes wrong I would bet money that it's a bad part and not their fault. Prices are reasonable and service is great.
