extreme nv5600
I have only had the transmission in my truck for a few weeks but I am VERY pleased with it's performance

Great replacment for the Higher HP guys
On a spirited drive I stripped 5th gear and snapped the input shaft on my stock NV5600. After looking at my options to rebuild or buy a reman I came across CPP's option. I regularly hook up to the Sled in the summer time and after talking to Jamie I was convinced that the warranty and price of a new transmission was well worth it. Swapping the old transmission for the new was a chore at almost 400lbs per transmission. It took CPP about 3 weeks to get the transmission from time of purchase to pick up, but with a snow storm in between I saw no issue with that. The new CPP Extreme NV5600 shifts smooth and quiet through all the gears. I have only put 3,000 miles on it but like what I see so far.
