Who and what is the cheapest performance 4l60e out there. What kind of build time are we talking about.

 

http://www.converter.cc/contact.htm The "Pro Yank" transmission can withstand up to 700 lb. ft. of torque! (compared to 450 lb. ft. stock)

The Yank "Sportsman Pro" transmission can handle up to 600 lb. ft. of torque

All 4L60E transmissions have extra clutches and exotic materials for maximum holding power while using "power adders".

The "Pro Yank" transmissions will shorten shift cycle time in half. This will decrease ET by at least 1 tenth!

Trans-brake applications are available, however an appropriately beefy rear end is recommended!
