These kits are designed to convert vehicles with original 331, 365 and 390 engines to THM 400 transmissions. In many instances, these kits will bolt on directly to the original parts but some may need some minor modifications. Professional installation is recommended for proper use of these parts. You are responsible to ensure parts are installed correctly to prevent unnecessary damage or wear to your parts. 

Changing the transmission will require changing the mount and driveline. Please see additional products that we offer in the related products below if you would like to use these. Please compare all measurements and information before purchasing to ensure proper fit.
