Perfect Tuning is excited to present our Dodge 8HP70 Transmission Adapter Kit, the ultimate solution for mating your Toyota 1JZ or 2JZ engine with the robust Dodge 8HP70 transmission. This kit is not only a testament to superior engineering but also to our commitment to quality and performance, and we're incredibly proud.

Custom-Fit Design 

Designed in Québec, Canada, our adapter kit provides a perfect fit for your Toyota, ensuring a seamless integration with the Dodge 8HP70 transmission. We have also designed the kit in mind for easy serviceability, unlike other kits which require dropping the transmission to replace the starter motor.

Wide Compatibility 

Our kit is compatible with a range of Dodge models from 2015 and newer, including the Challenger, Charger, and Chrysler 300 (which have the 5.7L HEMI).

Model Specific Kits

Additionally, we are constantly developing new complete kits for the various Japanese models, such as the A70 and A80 Supra, MKIII Chaser, and Lexus SC300. Our goal with these kits is to remove all the guess work out of completing your first 8HP swap. 

As you well know, the transmission adapter is only one of the many components you'll need to get your car on the road, and we strive to offer them all.
