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.

Customers are responsible for throttle position signal provisions. Check out US Shifts options for TPS Kits. Please give us a call if you're not seeing what you need!
