The Curious Case of the LH6 6L80 vs LS2 4L70
Thank you for your support and interest in this year long project, ladies and gents. 

We have successfully completed the conversion of our latest project vehicle, a Trailblazer V8 4WD; converting it from a 4L70E four speed automatic transmission to a 6L80E six speed automatic transmssion. Making it the world's FIRST successful 4WD conversion of a 6 speed automatic into a vehicle that was not designed for it WITH FACTORY CRUISE CONTROL, Tap Up/Tap Down shifting, and all original interior features fully functioning!

Primary focus has been for I6 ('08-09) and V8 ('07-09) GMT360 platform trucks (Ascender, Rainier, Envoy, Trailblazer, 9-7x). The '05-06 24x reluctor ring versions of these vehicles, including GTO and SSR) has also been addressed.

Other LS based vehicles are being evaluated, so please provided us with your feedback. 
We are now accepting orders.

6L80E MISSION ACCOMPLISHED!
