Just so you all know, at my Freightliner dealer I asked what a factory rebuilt Series 60 costs with a 3yr/300,000mi warranty- thats $16,000-and you have to have the old engine to switch the parts from. A brand new in the crate Series 60 is $65,000 ready to install! So $24,000 might be a bit high, but if it has all the electronics, trans shifter, gas pedal and wiring with it, it isn't such a bad deal. Good Luck, TomC
PS- got a general price from Pedco to change out my 13spd transmission (in my truck-and its' a cabover which is the easiest to work on) to an Allison HT740- $10,000. If I use the Allison HD4060 (like the B500)- $20,000 installed.
