I have a 98 379 with a 12.7 Detroit and super 10 trans. I want to put an 18 speed in but not sure all in entails. How do make sure I get the correct trans? Is there a place I can put my old trans number and it will let me know what I can use?? Ratios and length
Super 10 to 18 spd

That is a pretty direct swap if the replacement has the same shift tower location. Yoke is the same size or will swap. Halo or no Halo, not a concern if it comes with a bell housing. -
Super ten is the same length as a 13 or 18 direct swap except the shifter tower on the super ten is different

Pretty straightforward install from my experience. New clutch and clutch brake and a yoke to match your driveline. You will likely need to go to a driveline shop to have it shortened or lengthened depending on the conversion. New trans should come with shifter and color coded airlines.
