The transmission matched my VIN perfectly and shifts cleanly. Took an extra day to get the tracking info, otherwise this would have been a full five stars.

Really impressed with how knowledgeable the support team was about my hybrid setup. They sourced the exact low-mile engine I needed and even included install tips.

Engine performs fine once installed, but the freight carrier rescheduled twice and the harness clips needed cleanup. Worth it for the price if you can tolerate a little extra prep.
