Amazing experience from start to finish! The transmission is working perfectly and the price was unbeatable. Highly recommend!
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.
