Transmission:    4R70W - 700

This is our most popular 4R build.  This transmission utilizes a 300M input shaft and is built to dish out as much power as Ford factory parts can handle reliably.  It is fully rebuilt using F7 or newer cores we have available.  Each unit is fully inspected for wear, all gaskets and seals are replaced with quality new pieces, and final clearances are adjusted for performance use.  This transmission retains the use of lockup control, however it is not suggested for use past 700 ft/lbs of torque (with the exception of cruising in 4th gear).  Please contact me for details.
