Impressed overall
When my 4R100 started to go out on me. I found they're popular and hard to find. Even wore out units with as many miles as the one in my truck were over $2K. So I decided to look into rebuilding it myself. I looked up monster transmission since I see there ads on vilocity. The whole kit was under $800 and there customer service personnel were very helpful. When they say complete they mean it to. It had nearly everything but the oil. Out of the whole kit I only found one bushing was the wrong size. Considering there are I think 3 different sizes it could have been and they put the kit together for the transmission sight unseen. I can't hold that against them. They even include an upgrade kit for the valve body. So far I've been very happy with the performance of the parts. I think I'll be calling them again the next time I need transmission parts.
