2007 Volvo VN daycab with the d12 and a 9spd rt13709h. Just bought this truck and the transmission feels pretty sloppy, even after a new isolator.
I’ve got a Super 10 sitting around, thinking about swapping it in. The overdrive would be nice. Other than having the driveshaft cut to length, is there anything else I need to be aware of before swapping?
