Made right here in the USA from high quality 6061 billet aluminum, the ATF Toyota J3/A340E Bellhousing to GM PG Adapter allows you to use your Toyota J3/A340E Bellhousing. This allows you to mount your Toyota J3 or any A340E Bellhousing to a Powerglide Transmission. Our Toyota Bellhousing Adapter is precision CNC machined and ready to install. Perfect for applications with tight clearance such as small transmission tunnels and firewalls. The Bellhousing is not included in this adapter kit, what is included is all the hardware that is necessary to bolt the adapter to the face of the GM transmission.Note: When using the J3/A340E Bellhousing it requires a custom 9" torque converter with the Factory Toyota Flexplate. When using this Adapter Kit you will need to have a Custom Hybrid Torque Converter to be able to fit inside the smaller Toyota Bellhousing versus the Chevrolet/GM Bellhousing. The Torque Converter Bolt Pattern is the Factory Toyota Pattern which allows you to use your factory flexplate.ATF does offer a SFI Aproved Steel Flexplate (Part#:220426) for customers making in upwards of 700 WHP that can be used in conjunction with an ATF custom built Torque Converter. Making it a perfect marriage of performance and strength.
