<snicker> Looks like Jasper has a better rep than BD on these transmissions. My son has 2 of them in their fleet, 2014 and 2017, with a Jasper and unknown mileage but they still work. He adds a PPE pan and reusable gasket, cuz they always seem to have pan leaks, as preventative to start. If they show ANY signs of weird fill indexes or codes they get a Revmax Zero Flex VB immediately. Rebuilds get all the good parts to the tune of $4500. So far it is totally hit or miss on mileage, some go 280-300k before a rebuild is necessary. Several have not made 80k and they toasted the trans. Trucks are used hard by multiple drivers that really can be dumber than a box of rocks at times. Some units are just pointedly weird in how they react to rebuilds, the only consistent thing he has found is a Revmax Zero flex VB fixes all of the weird codes and OD issues.
