I am interested in any information on the 2010 Peterbilt 387. I am particularly concerned with the Automatic Transmission on these. Any additional Information would be appreciated. This Truck has a Cummins ISX Engine.
i put 189k on a 2007 peterbilt 335 and it ran like a champ,it was started up at 4:30 every morning and made 15 to 20 stops everyday and covered about 300 to 400 miles a day. it had a 300 cummins with an automatic allison tranny.all in all it was a great truck.
