They were very responsive to questions…
They were very responsive to questions before the purchase. All communication was very clear amd punctual. Shipping was quick. Trans actually shipped the day it was ordered. It was packaged very well. It included everything but the tools. Install was straight forward. Had instructions on how to program the shift module all without needing any computers of any sort. Gm 6L80 trans in a 2017 suburban. Put around 3000 miles on it so far and it drives better then it ever has for me. Would not hesitate to do business with them again

Thank you, Timothy! We're so glad the communication, quick shipping, and packaging all hit the mark — and that your 6L80 in the Suburban is driving better than ever at 3,000 miles. That means a lot to us. We'd be glad to work with you again anytime!
