Problem is that 2019 and up cars have auto rev matching which is done with a hardware change to the transmission, involving a hall effect sensor and harness that tells the computer what gear the car is in, which is information it HAS to have. So the only way to defeat this is if the Mach1 has the same plug and same sensor in the Tremec. But even then it will likely prove problematic since the Tremec will certainly have different gear ratios.A Ford GT350 TR3160 or another Tremec XL model, the second involves substantially more work. I believe that the GT and GT350 use the same reverse and temp sensor and it plugs right in. No custom driveshaft, mount, or shifter, direct Ford for Ford parts swap.
