The Tremec isn't God's gift; it's got problems of its own. There's nothing wrong with this transmission, as designed. It has a good record in other applications and is up for the power level and weight of the Mustang application. Ford cheaped out on some outsourcing for components inside and now they and their customers are facing the back-blade of that decision. It sucks but, I will make this car work, one way or another.
I completely disagree.... you can buy "tremecs" of varying quality... Crappy ones like they put in the Base Camaro/Vettes, all the way up the line to a fully blueprinted viper spec...... Show me where there are any upgradeable components for a MT82(I searched for hours)..... Oh, and most of the other vehicles that utilize an MT82 are diesels(and they are made in an award winning European facility), with a redline of 4K+ rpms below that of the coyote.... It's no wonder the input shaft bearing is disintegrating prematurely
