| Quite a few variations of that transmission. Find the spec sticker and see if it has a transmission model number. Or slide underneath and get the model off the transmission tag. Unfortunately, semis aren’t like passenger vehicles. So many options that a vin number is way more valuable then year, make and model. Once you have the model #, make sure the new transmission has an adequate torque rating and the gear ratios are correct for your application. If you’re serious about this swap, shortening the driveline is a drop in the bucket. New clutch, fluids, resealing the isx rear plate, it all adds up quicker than a guy thinks. | |
