Very experienced in transmissions. I took my car to multiple shops and finally to Qualifast and that's where it was finally repaired correctly. I highly recommend them.

Sometimes we are "fortunate" enough to put our trust in a mechanic who is honest and trust-worthy. I waited about a month or so to write this review, as I wanted to make sure that my car was working well, after my visit to Qualifast Transmission. I put my faith in GiGi, as I commute and my car's transmission was not running smooth, as it should. GiGi was direct and suggested trying new fluid before trying anything else (to rule out more serious issues). I also was grateful he applied the Diagnostic Fee towards the total bill; many places do not do this anymore. The car has been running 100% better for a month now and I feel confident driving far distances. I did not need a new transmission after all and I cannot say enough "Thank You's" to GiGi and this shop! I have already recommended several people to see him. Thank you for being honest and showing that some mechanics still do the right thing and act with Integrity. I will be coming back to Qualifast Transmission.
