Does this item come with its own preasure control solinoids/shift solinoids? Is it a stand alone unit or does it require parts from the old trans? Will a tune be enough to run this Trans?


  • The Performance Automatic C4 Street Smart Transmission Kit is a full mechanical/hydraulic transmission with no electronic transmission control. This is a complete kit and comes with everything needed to install, except fluid and a tune.

what will I need to get my speedometer to work I have a manual trans 2008 gt. Will be streeted very little. But would like to have speedometer. Also. Is this a manual valve body. Will I need a retune?


  • The Performance Automatic C4 Street Smart Transmission Kit (96-14 4.6L, 5.0L, 5.4L) is specifically designed for automatic transmissions, so this will not work if you have a manual.
