Are you planning on using a modern GM 4L60E, 4L65E, and 4L70E (1997 and earlier only) or GM 4L80E and 4L85E transmission with this kit? By adding a US Shift Quick 4 stand-alone transmission controller you will save $100 dollars off of the cost of your Speed Gems adapter kit. This kit will not work with “LS” based transmissions.
