Adapt any Engine to any Transmission with this DIY Adapter Plate Toyota C60 to Mitsubishi 3a92
Published at : 23 Dec 2025
In this vid I'm making a simple diy adapter plate to mate a Mitsubishi 3a92 to a Toyota c60 transmission. This transmission adapter plate is made from 3/4" 6061 aluminum. I'm using both 8mm and 10mm threaded inserts and the original starter location for the mirage. This is just a basic tutorial of my process, the results were great and did not require any special tools except a few taps. This is the adapter plate that I'm using for the new 6 speed celica gtx c60 that has worked out flawlessly so far.
