Summit Racing™ Transmission Mount Adapters

If you need to adapt old-style factory RWD transmission mounts to 8L90E, 10L80E and 10L90E transmission cases, Summit Racing™ transmission mount adapters are the way to do it! These adapters will allow the use of your original 2WD crossmember by retaining its transmission mount. They are designed to convert the unique trans mount pattern on the 8L90E and 10L90E transmission to a standard GM transmission mount. They are required when using 8L90 or 10L90E transmission and Summit Racing™ G Force crossmembers. The kit includes one adapter plate and two bolts.
